Drag & drop...
... isn't implemented yet ! The interface to play is a click & click one.
Go to "My messages", choose a game (click Game # or the rook)... the board appears.. click on the piece to move, wait the page loading, click the destination square, then submit.
Feel free to give me your impressions about the interface. Thank you in advance.

Games appearing in short list
Thanx for obeying my wish - now the "My games" list is much easier to read. But why can't I just click on one of the games in this list when I want to make a move? If you prefer, you could put a symbol (such as the white or black rook) next to the games where it is my move, to make it easier to see where it is my move. Then there is really no need to list the games (where it is my move) under "My messages" as well.

Minor notational bug...
In game 8, I had Rooks on f8 and b8. I played 18...Ra8 on the screen, but when I list the game, the move is recorded as Rba8. The "b" is superfluous, the f8 Rook can't move to a8.
In game 13, I had Rooks on d6 and d1 and played 18.Rxd8. This came out as R6xd8. The "6" is superfluous.
These are not serious errors, but it is a bit irritating....
Stefano Ghisi (2006-05-01 11:41:45)
Possible bug?
In the game 58 my last move was Rad1. I typed only Rd1 (with no specification of what Rook was to move) and the program has accepted my move as Rfd1.
Be aware! Every move typed and no moved on the board must me verifyed...

Start positions
It seems to me that changing the start position from classical chess is "sufficient"... The purpose was, according to Fischer, to avoid databases and to favour creativity.. The same positions in the whole tournament allows to compare & analyze a bit deeper, maybe understand better the position. The start position will be different for the next tournament (working on). There are "only" 960 positions, there will be repetitions anyway... And what do you think about the Fischer rules ? Seems strange to me. I wonder if everyone knows how to castle in other start positions (king or rooks at different places)
Thibault de Vassal (2006-05-03 14:15:54)
Chess 4000 ?
About Fischer Random Chess / Chess 960, the king' start position must be between the rooks to allow this strange castling. Why ?! Wasn't it ok to forbid this unusual (non-sense) move in these other cases... The number of positions should increase a lot. Does anyone knows the number of positions resulting ?

Big chess
The middlegame could be a challenge, particularly if you have no board to test the consequences of your move. And what do you think about an endgame with 12 pawns and 3 rook or 5 knights on each side? What are the values of the pieces? There is much to investigate there. Perhaps I should write a computer program ... (just a joke)
David Grosdemange (2006-05-30 00:28:03)
particularities of big chess ^^
we must take care about the possible endings ^^
for instance , knight+bishop can't win in big chess ^^ whereas 2 bishops (opposite coloured) still can win ^^
about a value , i think something like :
pawn : 1
knight : 2,5
bishop : 4
rook : 6
queen : 11

g11
Is it my impression or Kramnik wimped out of a rook exchange by 60...Ra5 and missed a good position with a passed pawn?
Most of the people should know my low degree of skill by now, so I'm just asking for help here to understand this. Why was so important for him to keep his Rook on the board over real winning chances?
Thibault de Vassal (2006-10-10 18:49:31)
Re: g11
With bishops on opposite colors, it's advised to keep a rook on each side to avoid a draw... Anyway, it seems to be a clear draw in all cases here.
If Kramnik doesn't win game 12, another battle will begin...
Rodrigo Jaroszewski (2006-10-10 19:18:09)
Hmmm
Even with a pawn up, Thibault? I mean, after 60...Bb6 61.Rxe5 fxe5, White being uncapable of threatening both Black pawns or moving his King towards either Black's passed pawn or his own pawn... Of course, it might come to a lock later on, but it does seem more promising than allowing the Rooks to stay.
However, you did give me the answer to my question. Thanks!
Thibault de Vassal (2006-10-10 19:49:12)
Opposite color bishops
These endgames are much easier than same color bishops or rooks endings.. The bishop & king can block the opponent's pawns (1, 2, 3 or more) in most cases, and the bishop can be exchanged against one or two pawns... In most cases the bishop has only to make aleatory moves and it's a draw.
There's a famous position with 8 pawns up... It's a draw too.
With rooks, it all depends... Sometimes it's harder to get a draw with opposite color bishops than same color ones.
See the 'endgames' Wikipedia article...

Gino Figlio (2006-10-20 07:56:02)
too many pawn captures for white
4 white pawns are still in their original post. There are however 3 doubled pawns. The minimum number of pawn captures to achieve this would be 7, but black has only lost 4 pieces(2 rooks and 2 bishops); therefore the position is illegal.
Wolfgang Utesch (2006-11-15 16:33:53)
Nice endgame
It is another endgame, but I didn't find any clear win with Rook+Knight+2 Pawns vs. Queen. But in the other endgame 3 Pawn vs. Bishop there is a clear winning way - complicate, but clear!

Fighting against Tablebases
Needing over a terabyte of disk space, I doubt if anyone actually has the 6 piece tablebase installed on their computer, though a position can be queried at:
http://www.shredderchess.com/online-chess/online-databases/endgame-database.html
BTW, I've played endgames here where I had to play the game out to checkmate where my opponent had just a king and a few locked pawns, while I had an advantage of a queen, rook, and several extra pawns.

Indeed after 14.-fg4 15.Qg4 f5 black is clearly better. But my Fritz-10 went 14.- e4/Bb2 and that is bad. However white can go 12.c3 Bd5 13/ed5 Ne7 14. g4!? hg4 15.Qg4 Rg8 16.Qf3 Ng6 and then 17.0-0-0 to save tempi for 0-0/Kh1 and connect rooks.I'll be back early next week for lines.

Big chess theory : "Queens opening"
The first rated Big Chess tournament started a few days ago... I like this game more and more, no theory, no databases, no chess engines, many strategies & many queens captured already ;)
Every opening seems ok, we still don't know if taking pawns with the queen during the first moves is worth something or not, the value of the pieces is quite unpredictable... Many players now play 1.Nh4 to threaten 2.Qo7 then 3.Qc7 if needed, winning a pawn. What is the best response if you want to keep the same material ? .. Anyway that's very interesting to see a side with 1 or 2 pawns more, giving some rooks activity to the opponent.. Still looks like a draw theorically.
My main line is : 1.Nh4 Nh13 2.Qo7 No14 3.Qc7 Ql13
Any other suggestion ?

Bobby Fischer's IQ
"In previous writings I have cited Fischer's I.Q. as in the range of 180, a very high genius. My source of information is impeccable: a highly regarded political scientist who coincidentally happened to be working in the grade adviser's office at Erasmus Hall - Bobby Fischer's high school in Brooklyn - at the time Fischer was a student there. He had the opportunity to study Fischer's personal records and there is no reason to believe his figure is inaccurate. Some critics have claimed that other teachers at Erasmus Hall at that time remember the figure to be much lower; but who the teachers are and what figures they remember have never been made clear."

Tablebases on R+B vs. N+N
Good to know this endgame (Rook + Bishop wins against 2 Knights in 150 to 220 moves in the longest cases - tablebases 6 pieces), as there's no draw granted after 50 moves without any capture according to FICGS rules.

re:
FEN used in encoding the starting position does not include castling information. You can add manually "KQkq" in the FEN line at the end, in the PGN file.
Fritz uses a non-standard encoding of the castling rights for Chess 960, with starting positions of Rooks not on A and H files.
Fritz should recognize castling rights, but the information is not included in the file. This is most likely an accidental omission, or it might have been done to avoid messing with X-FEN and the non-standard Fritz solution.
At this rate I'm becoming a helpdesk. :?

Game 17894
Hi Wolfgang I looked at this game last week - a nice game but I am not sure how complicated it is now ....rooks are generally better than bishops and it does help to have a king near the action!! Its like having an extra piece.

Poker
Poker is not really poker without a monetary wager, similar to backgammon.
Unlike chess or snooker, where a brilliantly played game can be satisfaction enough, the entire point of poker is to win money (cash game) or accumulate chips (tournament) by hook or by crook. Achieving this in practice has much more to do with exploiting mistakes and emotional weaknesses in your opponents than doing anything "brilliant".
As for "Play money" poker, it's for bored housewives and people who have too much free time on their hands. These are the same people who kill time by playing solitaire.
Andrew Stephenson (2008-08-19 02:16:39)
Its a win !!!!
You must be joking!! Thibault its a definite win it will be over in a few moves!!
If anyone thinks black can survive please suggest some moves. The key to the win is that the best black can do is reach the position in a) below with Bishop and 2 pawns v R and 1 pawn. White wins becuse his king has access to e4, the Bishop is restricted by his pawns on a7 and e5 and most importantly his passed a pawn is not advanced.
It has been completely lost since move 63 ...Kxf4 Janos should have taken with the pawn 63..exf4 would have allowed him to reach a table base draw. On 66 Kd3 I had the win completely worked out and have been replying instantly since then. Adjudicating this is a draw is just plain wrong. Anyone who spends time on this position will see the win I have outlined and that there is no defence. The winning method is to force an exchange of rooks by Rc4-g4 with mating threats against the Black king - black cannot allow this and must play Rd4 allowing exchange of a pair rooks when the resulting R+P v B+P+P is won. Before playing Rc4 white checks with the other rook to cut off the f file. The only way to avoid the rook exchange is to allow the white King access to e4 - at the moment the black rook cuts off d3 and the bishop if it goes to b6 will cut off e3. If the king gets to e4 either the e5 pawn drops or the king gets to d5 and e6 either result is fatal
Here are the main lines:
a) 72..Bb6 73 Rg8+ Kf5 (73..Kh5 74 Rc1 Rd4 75 Rh1+ wins the rook) 74 Rf8+ Kg5 75 Rc4! Rd4 (see below a1 for 75..Bd4)76 Rxd4! exd4 77 Kd3 (This ending is completely won the white king penetrates through e4, the black bishop is useless - remove pawn at d4 and its a table base win) Here are the main lines 77... Bc5 78 Rc8 Bb6 79 Ke4 Kf6 80 f4 Kf7 81 f5 Kf6 82 Rc2 Kf7 83 Ke5 a5 84 Rc6 Bd8 85 Bc7+ Kxd4 Table base win Or 77 ...Kg6 78 Ke4 Kg7 79 Rc8 Kf6 80 f4 (if the pawn on d4 falls eg 80 ..Ba5 81 Kxd4 its a table base win) Ke7 81 f5 Kf6 82 Rc2 Ke7 (82 ..d3 83 Rc6+ Kg5 84 Rg6+ and Kxd3 = TB win) 83 Ke5 Kf7 84 Rb2 d3 85 f6 with a simple win
a1)..75..Bd4 (instead of Rd4) 76 Kd3 Ba1+ 77 Ke4 Ra5 78 Rg8+ Kf6 79 Rc6+ Kf7 80 Rgc8 Ra4+ 81 Rc4 Rxc4+ (black cannot avoid exchanging) 82 Rxc4+ and this ending like the one above is completely won. eg 82... Ke6 (82...a5 83 Rc5 a4 84 Ra5 x a4 = TB win) 83 Rc6+ Kd7 84 Kd5 Bd4 85 Rh6 a5 (any Bishop moves loses a pawn = TB win) 86 Rh7+ Kd8 87 f4 x e5 = TB win
b) If the Bishop does not go to b6 the white king gets via e3 to e4 and then penetrates through the white squares d5 and e6 and its over. Sample lines:
b1) 72 ..Kf4/f5 73 Rf8+ Kg6 74 Ke3 Rd1 75 Ke4 Re1+ 76 Kd5 Be7 77 Re8 Bf6 78 Ke6 e4 79 Rc5+ and the bishop is lost
b2) 72..Ba5 73 Ke3 Rb5 74 Rg8+ Kf5 75 Rf8+ Kg5 76 Ke4 Rb4+ 77 Kxe5 with a simple win
b3)72 ..Rd7 73 Rxe5+ (take a pair of rooks off = TB win) Kf4 74 Rcc5 Rg7 75 Re4+ Kg3 76 Rc1 Bb6 77 Rh1 a5 78 Rhh4 - Reg4+ exchanges rooks = TB win

Strategy and tactics
Salut Thibault -- Military strategy and tactics are similar to chess. For example, the US opening in Iraq was flawed -- too few troops, overconfidence, etc., a bad strategy exposed by the insurgents' successful counterattack. On the other hand, this year's "surge" in Iraq was a tactical move, like moving a rook into an attacking position.
Actually, it was more like adding another rook in the late middle game ;-)
Normajean Yates (2008-10-31 03:38:44)
similarly,smallest natural *extension*-
similarly, what is the *smallest* natural *extension* of chess? [Again I am reposting this idea - i did it a few months ago]
Think about it this way, as far as way of moving is concerned, [keeping aside pawns for the moment] you have R, B, N moving in essentially different ways. Q = R + B as far as movement is concerned - i.e. a queen can move like a rook or like a bishop, as the player chooses. The movement of the Q is nothing more and nothing less.
So, to extend chess minimally and naturally [therefore extending the symmetry also] IMO the natural choice of new pice would be a piece which I call the superqueen, lets call it U [because S is knight in chess problems and in many non-english roman-script languages..]. The superqueen U moves like a R, a B, or a N, according to mover's choice. In other words, it moves like a Q or a N.
movewise, U = R + B + N = Q + N.
Now keeping symmetry and minimality in mind we get 10x10 chess with the following starting position:
rnbqukqbnr/pppppppppp/10/10/10/10/10/10/PPPPPPPPPP/RNBQUKQBNR.
In 10x10 castling O-O and O-O-O, it may be more natural for the king to move *three* squares [and the R crosses the king and goes adjacent to the new position of the king, just like in 8x8 chess.]
Actually long ago (1981-82) we tried this 10x10 a few times with some friends - we used to call *this* 10x10 thing 'big chess' :(
[we used a one-pound coin heads-up and tails-up for white and black superqueen resp.]
But the name bigchess is taken [and bigchess is nice :) ] , so I am just calling it 10x10 chess now..

34.Bf3 f5 35.gxf5 Rxf5 36.Bb7 *
The endgame 2 bishops vs 1 Rook + Pawn looks good for white. Black did not have any attacking changes in this game and white quite a comfortable game. However I am not quite sure if white can win it.
Hannes Rada (2008-12-25 21:12:07)
Game 1
looked very promising for White.
Without deeper looking into the position I thought that white is going to win here. But than I found that black has perpetual check due to his pair of rooks. With only 1 rook on booth side, i think white should win.
Wolfang, have you analysed a possible exchange of rooks at move no. 51
51. Rb7 instead of 51. a4 ?
I did not analyse this position, but at first sight this seems to be a good chance for winning this game.
Can you comment this ?
Wolfgang Utesch (2008-12-26 08:56:58)

Hi Hannes, I think position is after 51.Rb7 Rxb7 52.Bxb7 f4 = (i.e. 53.c5 Rf1 54.Ba6 Re1 55.a4 f3 56.a5 f2 57.Bb5 f1Q 58.Bxf1 Rxf1 59.b4 = key position!). Four pawns are not enough against the rook about the bad king position - surprising!
Also 53.a4 Rd7 or 53.b4 Rd3 are not better!
Hannes Rada (2008-12-26 11:19:40)

Yes you are right Wolfang.
In the key position 4 extra pawns are not enough against the rook in the key position.

Big chess pieces values
Hello,
I have just how terrible the board in Big chess are for the pieces, so, I would presume the pieces values are much differant than in normal chess.
I wonder, If a pawn worth 1, how much the knight, bishop, rook and queen would worth ? Forget the king as hs is alone and too slow to participate in the action.

thoughts on Big Chess... and tips...
I find bigchess more and more fascinating.. I Think it is a wonderful creation of Thibault's (I presume it is Thib. who created it: any way he offers it seriously on this site...) - the starting position is very well-concieved..
I think Bigchess needs more publicity. This is about the only place one can play it - and here there are 2-3 top-class players; less than 20 middle-standard players (including me); others try it once or twice and for some reason get scared or overwhelmed and give up - I see no reason why..
Bigchess gives no advantage on account of huge memorisation of theory, or of better engines: there are *no* theory books; and there are no known engines in existence (probably there isnt one - too little demand, and writing a *good* engine is somewhat laborious, coming up with a *good* static-eval function is tricky, fast board-implementation issues...), so it is all wits...
In fact last week I spend part of two days writing down whatever theory I could discover [with help from top games], it comes to half a page..
Tips for people who want to try bigchess:
1. Bishops are much more powerful than Knights. (because of much longer range compared to 8x8 chess).
The consensus on the values of bigchess pieces is David Grosdemange's valuation:
pawn=1
knight=2.5 (written 2,5 in the continent, of course)
bishop=4
rook=6
queen=11
2. In the opening position, the c,f,L and o-pawns are unprotected.
So, if white's opening move is with the j2-Knight ( freeing the queen), then on move 2 white can move the Queen and threaten to pick up a pawn by forks.. Similarly for black.
*However*, such pawn gambits are quite playable because the Queen can be forced to make many moves to capture a pawn, while the gambitting side develops their pieces.
3. Most Important For Many People: board for offline analysis.
Best of course, is to take time to draw a 16x16 board on paper and stick it on cardboard. And get hold of four sets of chess pieces.
Another way: print a position, and after a move is made - just update the position using correction fluid (typewriter/printer-ink erasing fluid) or something. That way you don't have to keep printng a lot of positions.
Normajean Yates (2009-05-12 00:47:43)
more bigchess thoughts..
compared to 8x8 chess, bigchess has twice the number of men but four-times the number of squares. Hence, initial and average board-population density is half that of 8x8chess. So, games are more commonly 'open' - games as closed as an 8x8-chess closed game will be comparatively rare.
Hence, also, (because of low population-density) long-range pieces Rook, Bishop and Queen are *in general* -- Thib., agreed: only 'in general' :) --- much more powerful than their 8x8-chess counterparts.
However, the queen can still get trapped early - see my game number 31191 - opp resigned on my [black's] 7th move because of trapped Queen..

Normajean Yates (2009-05-11 03:52:01)
Daniel, I think you underestimate Rs...
you give B=4, R=4.5 but in the endgame specially, the Rooks pull their weight..15th ('7th' file), escorting Ps to promotion, ...
About people playing on to mate after being a Q down or so without counterchances, well a bigger player-pool is needed ... plus I understand some newbie players not being so sure that mate is easy in a given pos (though much lengthier than in chess) - so, we need *more* non-newbie players!
And a non-newbie begins as a newbie: however, I agree that's not the whole story -- some people *will* play on to mate...one sees that in chess (8x8) too -
lets see: my bigchess record: 17/17 - wow! (with 1 pending: it is still in the gambit-opening stage)
Normajean Yates (2009-05-12 01:15:30)
bigchess thoughts+tips, #3: R v B
[re Daniel Parmet's valuation in his post] - both are longrange pieces but:
1. a Bishop can reach only 128 squares, a Rook can reach all 256. (and all the other standard reasons why the R is [in general] much more powerful than the B, they carry over to bigchess eg a R can confine the opp's K to an edge; K+R v K is standard easy mate, etc.)
2. In 8x8 chess, once you have a semi-open file, one tries to 'boost' a rook up that file (even if one cannot reach the 7th file). This is much more common, and much more commonly advantageous, in bigchess, because one easily creates a 'quasi-semi-open' file by pushing a pawn 4-5 squares ahead, and boosts a Rook up this 'quasi-semi-open' file.
Hence, I feel that just as in 8x8 chess, the Rook is nearly twice as powerful as the Bishop in bigchess.
Hannes Rada (2009-06-04 21:56:51)
Dead Endgames
Thibault, you are talking about endgames in this connection.
Do you mean for instance the famous rook endgames, which are always a draw according to Tarrasch :-)
And it is true, there are so many rook endings which cannot be won, with extra material. Even with 2 extra pawns ....
I had 2 times a position with K + R + f+h Pawn, against K + R which is a theoretical draw. Sometimes chess can be really unfair. You are playing much better than your opponent, you manage to to achieve material advantage of 1 or 2 pawns, but the rook endgame is still a draw ...
Here is a proposal against the broad draw corridor

"reformed chess", "improved chess"
Speaking of rook endings, of course some -maybe most- are dead or at least understood positions, some are very complex for the human brain... I don't think chess is so unfair even with 2 pawns more, every good player has to know the endgames theory, that's the most important part of the game IMO (at least when learning), such draws only show that one didn't manage to complexify the game enough.
Nice ideas in these links Hannes, and there are many others even without changing the way the pieces move (e.g. time handicap..) but it is harder in correspondence chess. Actually we may regret that chess is chess in this current version. As chess rules are everything but "natural", it could have been different, maybe it should have been. It is too late to change anything now because most people want to play the same game than Fischer and Spassky :) .. History prevails, even very intelligent recent games like Blokus will never be the king of the game.
By the way does anyone know about the drawish problem in Xiangqi and Shogi ?

Crazyhouse
You would need some special rules to prevent long boring clock time out waits, such as when one side is mated on the move. He will sit out and wait for the events on the other game. Typically what happens is that it will be mate on the move in the reverse direction. So either have adjudicated a win for the side with more time on their running clock or force them to move at least every 10 days say.
By the way if you try crazy house, you might want to also introduce shogi where pieces become the property of the opponent and can be dropped in. You won't need special char set since you can use the chess set with mods such as inverting them like the rook for the lance, golds can be queen, silvers inverted queens, etc and promoted pieces, the piece with a circle surrounding it.

Viktor Korchnoi and castling
Just noticed this funny story in a Wikipedia article :)
"Viktor Korchnoi, in his 1974 Candidates final match with Anatoly Karpov, famously asked the arbiter if castling was legal when the castling rook was under attack. The answer was in the affirmative, and Korchnoi ended up winning the game."
Most probably a psychological attack, like often at this time and particularly during the matches Karpov vs. Korchnoi ;) Everybody knows the yoghourt story...

yogurt story
http://www.mark-weeks.com/chess/78kk$$01.htm
I realised recently that i was unsure if castling was prohibited after moving a rook, then returning it to it's original square?
I believe castling is then prohibited - can someone verify this ;-)
William Taylor (2009-11-29 22:08:59)
Thanks
Thanks for the link, Nick.
You're right - can't castle after moving the rook, even if it's been returned to its starting square.

Value
Value is higher, my guess.
N - all fields, but horde moves for displacement, very slow piece.
B - only 128 fields, but only 2 moves for displacement (if clear board)
R - all fields, only 2 moves for displacement
Q - only 2 moves for displacement, but over one move, than Rook.
Guess
N - 3 (2-4) (From two pawns other sides any chance, but if pawns nearly, anyway 8x8 chess. Board 8x8 Notin, needed max. 4 moves, here?) Other tip? Mutually support afore own pawns.
B - 6(!) Very higher movement, than Notin. Other tip? Between own pawns, menace opponent piece.
R - 11 (10-12) Anyway 8x8 chess, pieces for middle game and endings. Interplay here is heavy work.
Q - 23 (20-30!) If interplay Rooks is heavy work, then Queen probably better, than two Rooks. Anyway 8x8, attention, traps and time for raven.
Sorry, my english language is weak.
Lazaro Munoz (2010-01-29 06:05:09)
Piece Values in Big Chess
I am amazed at the number of opponents that are still applying piece value from regular chess in big chess.
I made some regression analysis based on what we value in regular chess in terms of mobility and applied to big chess. Using the pawn and knight as the standard since in both games 3 pawns will probably beat a knight (if they are separated far enough). I assigned the pawn the value of 1 and and knight a value of 3 and extrapolated variables that we seem to use in valuing the other pieces such as number of squares it can reach, and penalty for being stuck on the same color.
I got the following values:
Pawn=1
Knight=3
Bishop=7 **
Rook=9
Queen=16
** The bishop value changes by pairs available, for example 4 white square bishops don't even come close to value 2 white squares and 2 black squares bishops so this is best value but it can go down to 6 or even 5 as pairs are lost.
Interesting, just like in chess a rook+bishop almost equals a queen and two rooks beat a queen. And a queen equals the value of the pawns (ok similar).
I still find opponents who exchange bishops for knights with impunity, not knowing the true values of the pieces.
I notice that nobody has ever mentioned this. I hope I did not give out some deep secret.
Of course you mileage may vary.

Ratings calculation
I don't quite understand the way that ratings are calculated (for initial ratings).
I entered my first chess tournament with an initial rating of 1785 (my ICCF rating at the time). I won 5 games and drew 1 and got a rating of 1837.
My fellow tournament entry Chris Brooks entered also for the first tournament with an initial rating of 1800. He won 4 games and lost 2 and got a rating of 1906?! No complains to him, only to the rating system.
Is there some draw penalty built in? We played the same set of players(so the tournament average rating is exactly the same) and played the same number of games (and no more, I checked this has so far been our only tournament for both of us), yet with my extra point and half I wound up with a much lower rating.
What's up with that?
Arno Bezemer (2010-05-20 14:57:17)
Late resignation
Normally I don't mind to play out a winning position, but my opponent in game 32535 keeps on playing for ever, with just a pawn vs my rook and 2 pawns. On the lowest level i can maybe understand this but not in a class M 2200+ tournament. Is there anything i can do about it?

whole database transfers made simple
Is this what your talking about ?
How to import my Chess games in a chess database ?
There are several ways to import your chess games played at FICGS in a chess database like Chessbase or SCID. 1) You may download the complete FICGS correspondence chess database: Click "Search games" in the menu, right click & save "All games (PGN)". Import the file in your database, then you may filter the games by using your name. 2) You may create a PGN file by going to "My games" (please use the chess filter, click the rook icon if you also play Go or Poker, you may also select pending, running or all games) then clicking the printer icon. You just have to copy/paste the content of the new page into a new text file, then importing it in your chess database. 3) You may download the PGN file of a particular game or tournament, right click and save the "download" link at the bottom of
Do you mean "left mouse click" if I right click I get Link copy options, none of which seem to do what I want.
I do not see a way to save "all games pgn" in any case which is what has stopped me for days. Left mouse click copies all database to where i want to open, Ie scid (which I cannot figure out either), notebad, but i see no filtering capability in notepad.
So I do not know how/able to do "Import the file in my database" as your instructions say,
sorry Thib, I am a pain in the butt. can you clear these things up for me ? especially your step 1.

Chess positions too complex for engines
This topic may last a while but it could be interesting after all.
Why not trying to gather (and discuss) as many chess positions as possible that computers are still unable to solve with the best engines even working during days... It may help us to detect more weak points in the most recent engines.
Okay, I start with these ones:
Schuster-de Vassal : 1-0
http://www.ficgs.com/user_page.php?page=viewer&game=36895&move=96
Peter played very well in this one but as far as I can remember this position was an easy draw... The plan was to keep the rook on the e column and White cannot progress. I knew that but at this moment, I had to play this move quickly and I made a stupid mistake: I trusted the engine... Rb8+?? 1-0 .. my comp was really a prehistoric one there but I wouldn't be surprised if the recent ones were still not able to avoid to play this Rb8+
The next position is less interesting but quite funny, and it looks like that the newest engines STILL do not understand it... Actually it shows +5.00 or even more while it is an EASY draw for any human player...
Utesch-de Vassal : 1/2-1/2
http://www.ficgs.com/user_page.php?page=viewer&game=11345
Amazing, what do you think? :)

Rybka banned from ICGA
Clone or not clone, I'm not sure if this question is worth something in computer chess but ICGA did it: Rybka was banned and stripped of titles...
I just partly read RybkaInvestigation document, a few points are particularly ridiculous (like 2.2 "Sudden Strength Increase"), I have no idea on the other ones and I'm not sure if this is really important in the real world.
Finally, the punishment:
- to strip Rajlich of all ICGA Tournament Titles and,
- force the return of trophies and prize funds to the ICGA and,
- ban his programs from future competitions until he can satisfy the ICGA that they are no longer derivatives and that he has satisfied the conditions of any other penalties the ICGA imposes.
- encourage other tournaments (Leiden, Paderborn, CCT, TACCL, etc.) to disallow the entry of Rybka until it is proven “clean”.

Thematic tournaments?
Good point. Thematic tournaments would help to find out whether some radical ideas like Brooklyn defense ( 1.e4 Nf6 2.e5 Ng8 ) can be defended against engine play.
George Jempty (2016-09-09 17:56:01)
Player of the Year
The game I am the most proud of the past 12 months is http://www.ficgs.com/user_page.php?page=viewer&game=89124 a draw against Ortiz in the first tournament mentioned above. I got a poor position with a poor opening and around move 30 was down around 0.6 to 0.7.
I took all 45 days of my vacation before December 31st and devoted almost all my analysis to this one game, with a new 8-core, 32 GB RAM machine, as well as buying Komodo 9.3 (I'm now up to 10.1). Ortiz did not play so accurately and by move 45 the engine evaluated me as completely even in a few lines but they were complicated and I was much lower on time than my opponent.
However I found a forcing line of about a dozen moves that the engine thought was inferior, but I knew was a dead drawn ending: R+2P vs. R+3P all on the same side of the board, with me also having a sufficiently active rook. So I went for this simpler solution which also let me gain time on the clock as I'd analyzed everything out beforehand. Finally after about a dozen moves in the ending Ortiz offered the draw.

7 pieces tablebases
By the way, do I read/understand correctly that Queen+Rook+Bishop can win against Queen+Queen in any endgame ??
How's that possible?!

New FICGS app: beta test
3 new FICGS applications based on the "Chess Trainer" app :
- Blindfold chess : same, but on en empty board... for experts, IM & GM.
- Chess 960 : the famous Fischer random chess version... much fun!
- Random : even more random, up to 7 knights, bishops, rooks or queens.
As for me, I quite like the "Random chess" app :)

FICGS chess cup : proposal
Hello Herbert,
I think you may misunderstand what Garvin said there: "The simple explanation is that I had the white rook on h3 instead of h2" ... probably meaning that the analysis was based on the wrong position at one time or another / since one or several moves.
Let's wait the end of the tournament. Of course, losses on time are always bad in such tournaments, but it can happen for many reasons.

Poll: renaming the Queen as Dragon
And renaming Bishop as Elf and Rook as Dwarf?
William Taylor (2018-04-01 22:11:41)
Poll: renaming the Queen as Dragon
Then you would have to give the Rooks/Dwarves the power to tunnel under other pieces, and the Bishops/Elves the power to shoot other pieces with their bows & arrows.

Poll: renaming the Queen as Dragon
During french Revolution, there was some propositions to rename pieces:
King = Flag
Queen = Adjutant
Rook = Cannon
Knight = Rider
Pawn = Trooper
only male terms

Big chess castling
Thibault,
Have you ever considered allowing players to castle twice in big chess, giving a mechanism to allow similar castled positions to normal chess? For example, from the starting position the king could castle once to kingside, ending up on l1 with the rook on m1, and then again, ending up on p1, with the rook on o1. He could also go the other way, finishing on c1 after castling twice.

Grand Dice Chess
Hello,
I am the author and inventor of chess variants. My chess variants are published on chessvariants.com and some of them can be played on Game Courier.
I would like to present to you a variant of chess with dice that I invented relatively recently and which can already be played on two sites on the Internet.
Grand Dice Chess
The Rules
The game uses a 12x12 board.
Each player has:
4 Kings
24 Pawns
8 Knights
8 Bishops
8 Rooks
4 Queens
White and black occupy the 1st-6th and 7th-12th ranks, respectively, as shown in the diagram.
Unfortunately I can't post an image here, but you can always find it here:
https://granddicechess.blogspot.com/2022/01/grand-dice-chess.html
https://www.chess.com/blog/Pokshtya/grand-dice-chess-battle
https://www.chess.com/forum/view/chess-variants/grand-dice-chess
White starts the game first.
The game uses four dice.
Opponents make moves alternately, throwing 4 dice. The piece to move is determined by a die:
1 = pawn, 2 = knight, 3 = bishop, 4 = rook, 5 = queen and 6 = king.
The player makes four moves at the same time based on the indications of the dice and has the right to refuse (pass) any move that does not suit him, unless it is a pawn move. Unlike in regular dice chess it's allowable to pass moves. And this rule was already applied about a thousand years ago in old variant of Shatranj (Shatranj al-Mustatîla or Oblong Chess), the Arabic pre-decessor of modern chess. However it's not allowed to pass on pawn-moves, except when they are blocked.
Chess pieces move across the board as they do in ordinary chess - according to the standard rules of move and capture.
The only minor exception is for a pawn that is not allowed to move forward two squares from its starting position.
Upon reaching the last rank, the pawn can be promoted to any piece except the king and itself.
There is no castling, check and checkmate in the game.
The goal of the game is to capture four enemy kings.
The first test tournament was held on the site http://abstractgames.ru/index.php
The tournament is attended by 10 people and I received the most positive feedback from them.
The game has proven itself so well that regular tournaments have already been launched.
Yesterday the game was added to Dagaz server https://games.dtco.ru/map
And it's a great place to test the game in person, as registering on the site is very easy and doesn't require any personal information.
The game turned out to be extremely interesting and exciting, replete with puzzling combinations. Surprisingly, with this size of the board and the number of pieces, the average game lasts no more than 30 turns.
Thibault de Vassal (2021-07-08 18:10:09)
Big Chess theory?
IMHO the queen is more worthy than 2 rooks... at least for human players ^^
Herbert Kruse (2021-07-08 19:26:19)
Big Chess theory?
for now i think:
pawn 1
knight 4
bishop 8
rook 12
queen 30
Ulises Pineda (2026-05-28 09:30:16)
Berlin Defense
OTB I like the Schliemann Defense against the Spanish, after 3...f5 black is completely fine and there's no winning line for white, but there are two other things. First, you can feel it in the air, Ruy Lopez players have spent a great deal of time studying it and they want to prove their superior knowledge aiming for lines where they win if black plays a small inaccuracy, which happens often and that's why they like playing it.
You take that away which is a psychological victory.
Second, they have two options, either they play fast and will most likely abandon the advantage because white needs accurate play to keep her edge, or they will sit to think on the best continuation, but after the position settles down it's equal and you come up with a huge advantage on the clock.
My favorite line is when you have your queen on d4 and they play Nxg6 because they're used to positions where capturing back allows white's queen to capture the rook on h8, only to find out they can't do that because it's protected by the queen! So they have to play Qxg6+ but after covering or moving the king black is already better!
It's as if I saw the Spanish die before my eyes like that, even if my wins are mostly on the clock, it has forced players to avoid playing it against me, because it's easier to go into some g3 and Bb2 stuff and beat me from there than figuring out how to play against 3...f5.
My only lament is its name, it would be so cool if it was the Schliemann Gambit, or Schliemann Counter-Attack or something that gives it justice.

d4 Nf6 c4
The most common move, played by 3 players out of 4, even more at a master level. The idea behind is quite the same as in Queen's gambit, giving space to white and controlling center. The c-file could be opened for rooks early in some variants, and the knight Nb1 now could jump to his most designated square c3.
According to Chessbase, white chances are about 58%

e4 e5 Qh5
This is called the Parham Attack. It's used commonly in lower scholastic tournaments. If used against a player who has the ability to see multiple moves ahead, however, the early over-development of the Queen will result in either the loss of the white Queen, or the loss of a tempo. The move is deceiving, because white is actually putting the e5 pawn under attack. If black counters by attacking the queen with 2. ... g6?, they lose a rook a rook to 3.Qxe5+. The most effective way to counter against this attack is to protect the e5 pawn. After the King pawn is protected, white's queen is left overdeveloped and subject to attack. Overall, the Parham Attack is only effective against beginning chess players.

e4 e5 Nf3 Nc6 Bb5 a6 Bxc6 dxc6 d4
An old move, played before Fischer's 0-0. After the pawn exchange, White creates a favourable endgame pawn structure, given his 4-3 pawn majority on the Kingside. Black is unable to exploit his Queenside majority because of the doubled pawn. However in practise, Black is able to to create sufficient counterplay with his bishop pair to hold the balance.
============
Actually, I think this is a bad move. After 0-0 black will have to defend the pawn on e5. 6. Nxe5, Qd4. 7. Nf3, Qxe4 does not work anymore for black, because white can play his rook to e1 and win the queen (the queen is pinned).
Therefore, black usually defends the pawn with f6. f6 is not very useful however, and black would rather have made another move, if he could have done so. Qd6 and Qf6 are also good moves that defend the pawn on e5. However, after 6. d4, exd4 7. Qxd4, Qxd4 black will have lost a tempo in comparison to this variant.

Black has more space on the queenside, and will fianchetto his queen bishop to bear down on White's kingside and deter a pawn thrust to d5.
Black's rook will contest the c-file.
With the centre almost blocked, Black may decide to put his King on e7 or f7, creating the opportunity for a kingside pawn storm, which might catch out a White who is unfamiliar with the defence.

Nf3 Nf6 b4
Santasiere's folly
A move so named because, when it was first played by Anthony Santasiere, he commented "oh dear, I meant to play it to b3!" Like the Sokolsky though, it is seen by many as more than a Basmanesque joke. White will aim to play a further b5, Bb2 and a4, gaining much queenside space and restricting the development of black's queenside rook and knight. Black will aim to prevent this queenside space with quick counter attacks on the queenside.

The most aggressive and risky move. Few draws emerge from this position. Black's aim is to get white's queen into the corner and out of the way so he can launch a mating attack on the white king, something he's willing to sacrifice the rook for. Taking the rook is sound though, as all of black's attacks can be easily seen off.

Slightly mysterious, but does create the option of putting the knight on f4, which might put useful pressure on g6 if the White queen comes out to h5+.
One reason why we are advised not to develop knights onto rook-3 is in case they are captured by an enemy bishop and you have to re-capture with the pawn. But in this opening, there are currently three of the opponent's own pawns preventing this capture.

A critical position. In order to understand why a single tempo will be decisive for the evaluation of the position, it's advisable to remember that Siegbert Tarrasch postulated that "two bishops plus a rook are better than two rooks plus a knight". According my oddly uneven experience of near forty years of tournament play, during which I lost to many patzers but beat many masters -and a few grandmasters- as well, I think Tarrasch's axiom is correct most of the time. Indeed, *as most players seem to not know about Tarrasch's axiom*, one of my dirty tricks has been to look for these positions, when my adversary think he -one exchange up- is better, but I -one exchange down- usually know better.
In this position, both Black bishops seem to have excellent prospects and, should my dark bishop be already at g7, I'd be sure that Black has winning prospects.
But it's White turn to move, and...
