Chessbase 10 with Xfcc is released!!
http://www.chessbase.com/newsdetail.asp?newsid=3749
PS...and I am GM Elmar Magerramov..

Part 3 is out ..(yawn)...
Okey, Okey, guys, that's not bad for an introduction of e-mail(?!) CC techniques for beginners..
But to be honest you shouldn't be wasting your time in this series and start doing more useful things like implementing the XfccBasic client protocol for correspondence chess servers. Even the IECG server has not ruled out its adoption later (hope you neither, Thibault ;).
But this must be done tout de suite, and the tooter the sweeter, as said. ;-)

Droppers: New rule
Unjustified resignations are equally disturbing (but not that common) so they deserve equal treatment in my opinion.
Silent withdrawers could be punished faster (quicker than 60 days) if time is doubled after 10, 20,..etc days.

Chess and politics
Look no further. Here it is.
The (Chess)Recipe for Success in Bussines and/or Politics
--------------------------------------
--(fortunately it had already been discovered)--
--------------------------------------
* Politics is a fairy tale of 1001 bad decisions.
* Bad decisions are all there, waiting to be made.
* Some part of a bad decision is always correct.
* The winner is the one who has made the next-to-last bad decision.
* Losses only prove that someone has erred in his decision.
* Moral victories do not count.
* To avoid losing a man, many a general has lost the war.
* It is always better to sacrifice your opponent's men.
* A threat is more powerful than its execution [the most violated rule]
* There is really only one big mistake - underestimating your opponent [The next-most violated rule]

Chess and politics
So Bush's national ELO is even lower ;-)
I assumed they may have won some ELO points by kicking Talibans' ass, but lost a lot more for playing dubious lines elsewhere in an otherwise easily won game --and now the opponent is playing the infamous Dead Man defense in the literal sense :((
Very sad and bad.
Elmer Valderrama (2007-03-27 17:48:51)
the second article...
..At least we got an inmediate response after the criticism ;-)
Once I am relieved from the headache of reading the first part of this very involved article, I'll post my comments..
BTW at first glance it seems the author has the bad habit of NOT giving an assessment to his annotated lines, ..or are we supposed to look at the engine's evaluation :-) --which are illegal to use, remember?!
Elmer Valderrama (2007-03-26 20:12:01)
The perfect title
As the title couldn't be more awefull, let's try to improve it:
"Decision Making: Invaluable Lessons Taken from Chess"
by G Kasparov
Instant best-seller.
Although the decisions of splitting from FIDE, creating a ghost GM association, not defending the WC in a proper Cycle, and....etc,etc..premature retirement, ..etc ..etc, don't speak too well about the lessons, let's try and improve it:
"Decision Making: Invaluable Lessons Taken from Chess, With Emphasis in What Not to Do"
by G Kasparov
A killer.
Elmer Valderrama (2007-03-26 19:18:28)
imitate = model
..nice description of the candidates' campaign strategy, Thibault :-)
How Science model Reality, and How Chess model Life, does it make sense to you? Hope so, since the object to be imitated is Reality or Life, and the imitator must be smaller/lesser by definition. (other synonyms are: imitate = try to be similar to = tend to look like = model)
Elmer Valderrama (2007-03-26 18:15:28)
How Life Imitates Chess
Has it been already published?
To start with, something tells me that the title should have been: How Chess Imitates Life, as it is written by a chess player not a philosopher or politician.
Not just because there is nothing bigger than life, but because we would be in real trouble if we had to make use of chess methodology to find out how to make the right decisions in life.
It can help, true, but no more than it did for Napoleon, for example ;)
(--Wellington would be turning in his grove trying to claim a Master Norm for Waterloo ;)
I have real difficulties trying to grasp the link between chess and politics.
Was Churchill a chess Master? if that is so, then Bush and Blair must be ELO 1200 ;-), and Garry must be declared Russian President ipso facto
Which French presidential candidate from your list plays chess?
Which one is considering learning some chess strategy?
Would they get more votes if they declare this intention? -sort of getting into their rights minds and improving their decision making? Hey, Garry is missing some prospective customers here..8-)
Elmer Valderrama (2007-03-26 11:47:37)
Oh dear
I've got nothing against chessbase, but as you can see, they go so low quality that is impossible to ignore them ;)
The main thing from this article (ie shot in the foot) is that actually nobody learns anything about how to use ChessBase in Correspondence Chess :)
All we got is a careful description of what is legal or illegal !?
It would be good if the second part is written by someone a bit more experienced but as it seems there is no-one available there, at least the author could benefit from reading some other CC forums (although judging by the "hope my opponents are using engine(Fritz) assistance" which looks familiar to me ;), they could be reading this one 8-)
Elmer Valderrama (2007-03-26 11:29:35)
How Life imitates Go
..any takers?
From what you guys write it looks more promising than Life imitating Chess.. --for if Chess can be programmed, can Life ever be ? ;-)

"Slow" Money
+1, Nick
(Count with me on that too)
Elmer Valderrama (2007-03-13 18:43:31)
Why isn't there a Chessbase forum?!
..any ideas?
The best I can think of is...they would definitely benefit from one..or maybe not -and that's why there isn't any ;)
Example, we could learn about CB freestyle tournaments impressions there, or about performance of programs, or about recommended books, DVDs, etc, oh well thanks God there are other forums ;)

Quotes from the forum...
I picked up a few ones from the forum ! .. I have great ones by Elmer Valderrama, Ilmars Cirulis, Don Groves and Heinz-Georg Lehnhoff. I keep it secret and I'll add it very soon, I think the authors will appreciate :)
Feel free to suggest me other ones...
Phil, about your quote it also happen at chess ;)

Anand virtually ranked #1
Maybe he's just started to overcome his I-can't-do-it-at-this-level syndrome :)

Elmer Valderrama (2007-03-11 10:41:50)
It's a draw on perfect play.
I agree, in CC 1.e4 is worse by test.

Playchess Freestyle Tournaments
I'm not that concerned about just bringing a bit of human brain into the game, I'm most concerned about bringing a bit of human brain into the game *successfully* :) i.e. for a start, real chances to beat operated Rybka at this time control. Hope you are right, I am just rather being optimist on your proposed time control.
--The 'money' prizes are now listed as Epoints not Euros, but what's the equivalence between them?
Elmer Valderrama (2007-03-10 16:17:33)
Playchess Freestyle Tournaments
1hour+15sec per player makes 2hours and 20 min for 40 moves overall which is significantly worse than 4hours for 40 moves overall, so I guess yes you are right (there is enough time to beat Rybka)
Elmer Valderrama (2007-03-10 15:56:59)
Playchess Freestyle Tournaments
..Well, I would play only Black there, so I guess I know who could be my opponent in the first Gold thematic -isn't there a Platinum with 1000 EUR at stake?! ;)
Elmer Valderrama (2007-03-10 15:27:33)
Playchess Freestyle Tournaments
Interesting and true observation, Thibault.
What about the format 2h/40moves displayed under Money Tournaments in Waiting Lists? Maybe this is equally harder (in order to beat Rybka) that at 1h+15sec (!?)
And second question is why do you think Black needs so many moves to have winning chances in the proposed Silver/Gold Thematic game, or a better question could be: Do you think White can get a draw after that sequence: 1.Nf3 Nf6 2.Ng1 d5 3.Nf3 c5 4.Ng1 Black to move. -->assuming the idea is that if the game is drawn White would win the 1-game match--.
Elmer Valderrama (2007-02-23 22:02:35)
Oh my..
*in the same vein* I'd say Kasparov would score 4.5 given that he's younger than Fischer but equally out-of-form and with a bad record of blunders in his last couple of years..:P -somehow Kasparov's die-hards think that he retired in the 80's, lol, ...and that this year is 1987 :)
Elmer Valderrama (2007-02-23 21:24:07)
Karpov
In terms of who kicked more, excuse my french, ar*ses?! Probably Anatoly Karpov.
Elmer Valderrama (2007-02-23 18:25:51)
Fischer
In the same vein if Fischer comes out and plays in Linares/Morelia he'd score 13.5/14, blowing all his opponents despite playing the same lines he always played and revealing novelties no-one thought about even with the help of computers...
(must be Friday, :P)
Elmer Valderrama (2007-02-17 10:59:30)
like a no-smoking zone?
I believe what Aldag want is a place with a sign "computer-free chess" just like those pubs, restaurants, trains, etc use a "no-smoking zone" sign. It will be visible so that it will deter smokers/engine-users to enter that zone.
To make it less attractive to engine assistance, these games should be unrated, with player automatically losing their current ELO (that ELO rating could have been "won" using engines previously anyway) so just their names will suffice, and there should not be no tournaments --so that there is no "winners" as this will trigger the use of engines-- The players will only challenge each other and the winner will not be known to anybody except the players, and the games will not be recorded in the general database and they will not be shown live: all this will for certain deter any need to use an engine i.e. 'winning' means nothing literally and it will look as if it never happened
This way chess without engines will be as if doing something clever when actually it is a loss of time -can't remember who said this about chess 8-)
Elmer Valderrama (2007-02-11 19:56:12)
Topalov suspected
Following the article's gestures argument ("touches his nose, touches his toes, touches the ground, and turn around") I think this must make him his 'teddy' by definition
8-}
Elmer Valderrama (2007-02-10 13:55:59)
teddy-bear-free chess
That teddy bear is worth 350 ELO, my guess.
Actually everyone has his 'teddy bear': it might be a blue shirt, the black shoes, or taking even his own mother/wife to the games (no punk intended to concerned players ;) ..All of these get scanned so I do not see any good reason why the teddy bear should not be scanned both before and after the game. If game is lost by the child there is no need to scan it of course. If game is won, then the teddy bear must be confiscated temporarily for further examination. Measures should be taken to shift the child's preference to any other object or person, as this teddy bear is starting to look rather suspicious to me/many, and annoying to his opponents who would then bring on dummies, milk bottles even nappies making this scenario rather...childish, unacceptable for a intellectual game as chess. Moreover, there would appear chess variants named after this toy, as 'the Teddy Bear Attack', or 'the deadly Teddy Bear Gambit' which could be played while singing 'teddy bear, teddy bear touch your nose, teddy bear, teddy bear touch your toes, teddy bear, teddy bear touch the ground, teddy bear teddy bear turn around', any of which would kill the game. In fact if nothing is done against this teddy bear, hereby I announce that I would quit chess, rapid chess, blitz chess, postal chess, email chess, server chess and correspondence chess (where admittedly is difficult to guess if there is any teddy bear around) I will then switch to a table game where teddy bears aren't going to be seen for a while, like Poker, or Roulette, all 18+ games
Yours in Teddy-bear-free Chess,

practical play
I believe this can happen at all levels: at +2700 level for example, A Morozevich illustrates the case, +2951 Perf in Pamplona, not too awesome in big events, Linares or WCs :/
-I think he might be easily the Most Practical Player of All Time --if that award exists--

Wikichess, javascript with comments?
(thanks Kieran for your support in the thread "WikiEndings"! hope you'll like this one too :)
Just looked up some lines in Wikichess but I had to go though every move with the browser, not with the javascript cleverly provided to view the line/game so far, to see the contributions from players. However if the comments in the line could be attached to the moves in the javascript it would be great as it would be seen as a "commented game", just a thought.
Elmer Valderrama (2007-01-13 11:23:38)
WikiEndings?
..is it feasible? (I'm sure it is, it's just a rhetorical question ;)
I believe endgame theory (and players) would benefit from a endgame section in Wikichess contributed by members taken from their practice, especially if general "rules of thumb" and guidelines are outlined together with analysis. Specially interesting I think would be many-pawn endings and other practical endings which are given poor coverage in the books and are less investigated (and, as it seems, there are always holes in the analysis even from very strong players, there would be a lot of room for improvement of the articles until a general consensus is reached)
Subsections could be created in the lines of the ECO classification for endgames, it would then be easy to find/correct/contribute in a given position.
Any thoughts?
Elmer Valderrama (2007-01-03 11:00:42)
Blitz correspondence chess
Well, as long as it's an unrated chess game, you can call it Silver Thematic and virtually any variation would qualify as a real chess game..
The way the winner is chosen in a 1-game (or 2-game for that matter) match is what is debatable, it's a little advantage to have White that's why having Black would be good if the color decides.
I think that players would agree to enter a tournament under some conditions (e.g. as playing on Satuday 3pm & Sunday 3pm), people were/are happy to enter the Chessbase "marathon" (freestyle with 3 rounds per day) and most here hang around making several moves per day in their CC games every day, so it's a matter of agreement about the appropiate time (easier to achieve with just two players (2-game match) than a tournament of course)
Maybe a poll would help although the players who would enter these events may not be even registered to FICGS yet, lol
Elmer Valderrama (2007-01-02 20:43:37)
Blitz correspondence chess
Programming problems you mean?
In a 1-game match I would gladly play Black all the time :) -provided that if draw Black "wins" of course-
It's tricky to make a fair 1-game match; the old proposal of giving odds to White (first two consecutive moves in a MUST WIN -other result loses- situation) would give White -I reckon- 60-to-70% chance to win, which is about the same odds as playing Black for a draw. But it's something new, which could be tested. Here I could play Black just to try to prove me wrong, lol.
Elmer Valderrama (2007-01-02 18:41:01)
Blitz correspondence chess
Do the games have to be played at the same time?
I mean if the time format is 4-6 hours per game, a 2-game match will be over in two days (weekend?), and a tournament of 6 rounds -in a week (or two weekends)..
Elmer Valderrama (2007-01-02 18:19:12)
my try
Miguel was quicker, here is my shot at it anyway (I thought it was a requirement for a referee in international CC to have a good command of English..]

Elmer Valderrama (2006-12-31 11:01:04)
Blitz CC
It looks like half-way between chessbase freestyle and rapid CC time control, personally would prefer the old OTB control of 2h + 30min for 40 moves + 1h for 20 with adjourn; or similar TC.
Another time control variation on the 10moves/1h format would be to add an adjourn (suspend for a later specified time), this could be done after 4 hours of playing (or 6 hours) Then, players meet the next day after some home analysis for continuation with the same format (+ second adj after 4h or 6h)
I presume Thibault will enlighten us soon on this subject.
However I think it would be nice to let the player choose a time control for a chess challenge (duel) so all flavours and individual tastes are met.
Elmer Valderrama (2006-12-30 12:11:08)
Quad_Silver?
Would it be a money 4-game tournament? if so, what's the money prize?
Elmer Valderrama (2006-12-30 12:10:13)
correct
I can confirm that Marc's translation is correct
Elmer Valderrama (2006-12-06 14:21:49)
Deep (serious) dissappointment
..I think Kramnik website motto
"time is precious when you don't have enough of it"
couldn't be more true here: give him a CC time control and it would have been 0-1. ;)
Elmer Valderrama (2006-12-04 14:32:04)
Deepy, the drawing monster
Now it's clear why CB was willing to pay 1 million if defeated: with Deep Jok..uh.. Fritz, they have created a drawing monster!!
At least it comes with a 1/2-point Life Guarantee

Elmer Valderrama (2006-12-04 14:18:02)
intuition
I disagree, chess knowledge can't be equated to intuition, here is my long post about it (why am I writing about the same things all over and over and at the same time of year, I dunno ;)
1. Players without any intuition whatsoever but great working capabilitites (as Botvinnik, Fischer, Kasparov, ..engines..)
-they never relie on intuition (they dont have any at all after all) so everything must be subject to calculation, they have the "hardware" (perfect body and mental conditions, rigorous training, perfect visual/realistic representation of positions and a great chess knowledge which must be kept fresh in mind -if not, they wouldn't have reference points to judge/evaluate resulting positions.
When on top form they can beat anybody and I mean ANY body: human, extraterrestial, ultragalactic, trans-natural, hyper-divine,etc, and for an overwhelming score, like 6-0 ;)..well you know what I mean.
The drawback well you already know it, it last a mig, except for the engines, no-one can keep up with this regime (GK could for a long time, but resorting to short breaks (not playing for WC, choosing carefully where to play etc,) But most important it's impossible to implement for long if the "hardware" -see above- starts to "leak oil" then it's all over..
This can be brought up to an art, like Kasparov or Fischer, it is more powerful than understanding chess as a natural tongue (as intuitive players) because the "top-form" competitive element is always present and the "hardware" works in pristine conditions.
From the above it follows of course that engines are the ultimate chess warrior over the board at least (and only there, not in CC)
2. Those who have strategical intuition. (Capablanca, Petrosian, Karpov maybe Anand..)The general impression is that they are simply lazy people: not need to work out any thing as they just "know" where pieces should go and what the point is of their moves, usually there is no need for deep calculations, just two or three moves (4 to 6 plies) to corroborate the "feeling" and the game is won.
The "feeling" is hard to express in words, and usually is lost if expressed in words ;). It goes beyond a simply pattern recognition, or a full database of chess knowledge, it is about predicting the future possibilities (not having real positions in mind, just the "possibilities" or general lines of play in future positions which may or may not happen to appear for real in the game. They can play for long long time and win a lot of tournaments (Karpov I believe have the record of won tournaments)
3. Those who have special understanding in unbalanced positions (Alekhine, Tal, Korchnoi..) They are dynamic players who love to calculate but not for the sake of finding the best of the best of the best of the moves (as those in group 1 would do), they calculate SOME variations, those who have meaning to them I see them as players of group 2 with a more or less working "hardware" i.e they are not going to trust 2 or 3 moves variations neither they are going to speculate on the future possibilities without any ground/basic calculation under it. Their "feeling" is again hard to express in words, but I believe it is something like calculating a 10-12 plies variation with every position in-between being subconciously excrutinated for crushing unexpected turning moves (this is not done by players of group 1, they would calculate "normal replies" in that 10-12 plies variation and would have to go deeper (like 20-30 plies to see the point ;)
So that "feeling" is what enable us to compose music, create art etc but also it is something that enable us to err like fools :( Whether it can be mimicked by software or not it's an open question but as I said a calculation 40-50 plies deep it's practically equal to using intuition... Obviously the above classification of G Kasparov it's a bit rough in the sense that there are very few "pure intuitive" players (of either group 2 or 3) as mentioned by Don in his post most of the players is a mix of talent I believe, if I had to choose a pure intuitive player from those groups I would point Capablanca and Korchnoi, and of course Kasparov of group 1
Elmer Valderrama (2006-12-02 15:31:47)
On the subject of intuition
Just received an e-mail from a known online book dealer inviting me to order the fifth Volume of G Kasparov's My Great Predecessors(about Korchnoi and Karpov).
I had a look at the online pages of the book (first three or so) and there is a paragraph about a proposed (by G K) division of players according to -guess what- intuition:
1) those players without any intuition but hard work (Botvinnik, Fischer..)
2) those with strategical intuition (Capablanca, Petrosian, Karpov..)
3) those with non-balanced positional intuition (Alekhine, Tal, Korchnoi, Kasparov..)
Very interesting reading. I guess we have to place engines in group one ;)
However, I would place Kasparov in the same group one of those without intuition but hard work as the criteria shows that players from that group tend to quit chess earlier (Botvinnik was on/off through his reigning) than the intuitive players who last longer (with Korchnoi the Terrible heading by far the lot)
Elmer Valderrama (2006-12-02 13:56:38)
Deep Joke
You have to agree that it's hard to be serious when a new program is more like a joke, a Deep Joke that is :p
OTOH I expect CB to get serious and release a really strong version of the program.
Elmer Valderrama (2006-12-01 22:13:19)
good news and bad news
Some good news and bad news for "deep" Fritz 10 (& CB..)
The good news is that game 4 was drawn with the computer playing a respectable good ending as White which forced Kramnik to display all his arsenal of strategic knowledge in endgames and his World class mastery to calmly withhold a difficult position...
The bad news is that "shallow" Toga would have played the same good moves made by Kramnik :-}
Elmer Valderrama (2006-12-01 21:07:50)
intuition
I haven't got even Fritz 9, so can't answer the question..but regarding engine development, I believe they lack any chess intuition, it would be a major breakthrough to implement one
...although apparently brute force at 40-50 plies = intuition :(
Elmer Valderrama (2006-11-30 18:22:46)
buy it!
..the more I look at the games the more I wish CB could sell out "deep" Fritz 10 especially to my fellow CC opponents..
:^)
Elmer Valderrama (2006-11-27 20:40:39)
one move deeper..
..well, "Deep" Fritz 10 is at least one move deeper than Kramnik
Kramnik blundered mate in 1 in game 2 :(
Elmer Valderrama (2006-11-27 19:40:07)
not that Deep?
..CB shooting themselves in the foot as this reveals "Deep" Fritz 10 is reeling in the endings :/
Not so "the others" which wouldn't play that endgame like that.
Elmer Valderrama (2006-11-24 19:12:58)
!!
..They could have agreed on just one rule: the take-back rule for Kramnik only
8-)
Elmer Valderrama (2006-11-23 22:40:29)
draw
I think everybody "knows" that it's going to be a draw 3:3
(I wish Kramnik won, of course ;)
Elmer Valderrama (2006-11-07 19:34:10)
Motivation
It appears to me Fischer's approach to chess it's a simple case of (lack of) motivation, if you haven't got any everything seems dull and grey. On the opposite side is V Korchnoi, older than him, but with a lot a will and of course motivation.
Of course having been at the very top preclude any further motivation, perhaps that's a curse to every WC (they can't just go on playing chess for fun as other GM (wanna-be WCs) would do -and be happy at the same time-, exception could be M Tal)
Elmer Valderrama (2006-10-20 21:55:18)
retrograde analysis
from math.harvard.edu
"Legal position (n.): a position that can be reached from the initial array by game consisting entirely of legal moves, however bizarre. Conventionally every chess problem should have a legal position. Naturally then, an illegal position is a position that cannot be reached by a legal game. For instance, a position in which one side has more than 8 pawns, or has both White and Black Kings in check, is illegal (why?). So is any position with a White Bishop on h1 and White pawn on g2 (why?), such as the following mutual Zugzwang (q.v.), which Lewis Stiller discovered in the course of an exhaustive computer search: White Kg6, Bh1, Pg2; Black Kg4, Pg3. The Kniest position White Kc8,Pb6; Black Ka8,Pa7 (seen above under Helpmate) is legal BTM, but not WTM since Black is in ``retro-stalemate'': Black could not have made a legal move to reach this position. [Thus this position can be set as a Helpmate in Two but not a Mate in One (or ``helpmate in 0.5'').] There are positions that can be recognized as illegal only after extensive retrograde analysis. To prove that a position is legal, one need only exhibit a single legal game reaching the position; such a game is called a proof game. Some retrograde analysis may still be needed to construct a proof game."
I bet nowadays there exist a problem solving chess engine which can give such a 'proof game' in 0.0001milisec (as the moves maybe bizarre, no need to evaluate positions, just to check them for legality)
Elmer Valderrama (2006-10-20 21:24:52)
quite a lot!
Thanks for your comment Thibault
Out of curiosity, just searched the Chess Problem Database Server and found a lot (+200!)of chess problems that have been found illegal one way or the other (not sure yours is listed there but I presume it is)

like toilet going?
..I think this tactics looks like the CC analog of going to the toilet 50 times per game..

other surreal mating positions
..I mean mating as in mate in 2,3..;)
There are far more surreal positions even with fancy names for each of them however no-one calls them "illegal" why is it? ..just wondering..

Toga
Since everyone is being honest in this thread here is my confession..
Usually I use latest Toga, I bought Rybka 1.2 series, but I've found it is not better than Toga, especially if run in a slow computer (I still use a AMD +1600, with Windows 98: I know I should buy a better computer but this one is already a recent "upgrade" from a Pentium 700Mhz running Fritz 8 ;) and I dont want to fall in the endless (and costly) chain of keeping -up-to-date just to get a few more ELO points ;)
Sometimes I test the positions with other engines (Fritz 8, Schredder 8, free Fruit) just to prove how right was Toga in the initial evaluation. In those rare but happy occasions when I make my own input is simply to give an idea of where should the engine "think". When things go well, after some point, it is just a matter of setting the engines on my opponents, they would finish the job.
Elmer Valderrama (2006-10-04 22:31:46)
engine use
I believe a player should be stronger than an engine (in terms of positional understanding) to get a feeling of where the centre of gravity (of the analysis) should go to have a "win".
If left alone/by themselves, the engines would make very stupid things, that's why they are in severe need to be told what opening to choose, eventually what line, and in the line, what series of moves -so called "plan". The difference in strength -given that engines are now public/free and very strong- lies in the difference in playing skill between players, if not in the computer power owned by them, in my opinion.

Danailov accuses Kramnik of using Fritz9
In my view, the best proof of computer use is the number of missed oportunities rather than the number of coincidences, which can be manipulated as pointed by Thibault. Thus, an average player misses 80 to 90% (99% in the worst cases ) a Master - 30-40%, a GM 10 to 20%. With the extreme -no missed oportunities we have those reported cases of cheating in Tournaments by average players So the suspictions would be worth something if they are accompanied by the report of (not)missed oportunities, otherwise the moves are in the usual coincidence range.

..f5?? > ...f5!!
..100% agreed.. they are (especially Topalov) playing variations which make sense to enter only in engine-assisted chess (CC)... (as a result they are tired after calculating the first set of 8 variations with 18 non-forced plies each ;)
Regarding the match, fingers crossed Topo will pull a Phoenix as in other tournaments when he was -2 after the first round...

FICGS correspondence chess database
That's a great improvement on the former listing of un/finished games (somehow it took ages to load those pages on my PC).
Now why is it that it will be updated 'at least' every 2 months, not daily as the former pages? (assuming fetching all the PGN scores into a single PGN file is done automatically by a script) Thanks

5 moves in fact
..just checked the thematic tournament 0007 on this sequence, and in fact White has 5(!) extra moves at the starting position (as it's his turn after 4.Ng8). No surprise most of the games are 1-0 (there are a couple of 0-1 too)
So 5 moves are too much; same would be for 4, or 3,..to me 2 moves it's a reasonable deal for Black (i.e. if draw Black "wins")
Elmer Valderrama (2006-09-16 13:49:35)
better extra moves
..I'd like to have a choice of those 4 extras moves: Nf3,d4,e4,Nc3 are not the best, IMHO ;)
Elmer Valderrama (2006-09-16 10:54:22)
2-games matches
The test ground could be 2-games matches between weak v weak, weak v strong, and strong v strong players(*in the ELO sense) : in the first game, the player has odds of two moves, in the second, he must defend the side with two moves down..
This could shed more light into this scheme..
Elmer Valderrama (2006-09-16 10:20:16)
color won't matter
yes, color or turn to move at start has little importance: Black to move, he would play 0.d5 1...Nf6 now is White to make second move 2.Nf3 for example..then Black would have 66% chances to win... (or at least significantly more chances than in the usual starting position)
I mean 66% to win, 33% to draw and 1% to lose ;) (that's 34% to draw and lose)
I think the more moves are given to White(Black) the more advantage he will have, i.e. statistics would be higher to win (like 80%, 19.5% to draw and 0.5% to lose) However all this could be tested in practice, it certainly could add more picant (spice?!) to the game ;)
Elmer Valderrama (2006-09-15 19:59:46)
two moves from the start
Interesting idea, Thibault, for having a winner in just one-game match. (I mean of course giving clear advantage to White from the start in a must-win game (any other result would be failure).
In this same line of thought, I would suggest to give White two consecutive starting moves (no captures allowed), W player chooses which are those two moves ( 0.e4 1.d4 or 0.e4 1.Nf3 or 0.e4 1.Bc4 or why not 0.e4 1.Qh5!? or whatever )
However, in all cases where White is giving a significant advantage at start, I believe, White has a 2/3 (66%) chance to win, and 1/3 (34%) to draw, so that in a match a strong player with White should go the next round. (assuming he has played the best two consecutive moves and then mantained the advantage all the way --although with the current wonderful defending capabilities of the engines it could add some serendipity to the game ;)
Elmer Valderrama (2006-08-27 11:17:48)
opening idea
..aparently everyone was/is impressed by the game Spielmann-Cohn, Carslbad 1907... --> White get such a big advantage in development that it's hard to think Black will get away with anything best than a draw here..

bug: en-passant captures
In the ongoing games of players Herr, Jeff v Sarihan, Sefa FICGS_CHESS_RAPID_C_000004 and FIGCS_CHESS_CLASS_G_000003 there is an "en-passant" capture (move 10.dxc6) which is not allowed by the chess rules (as I know them, maybe FIDE Congress has already changed them ;) The pawn c was first moved to c6 (3...c6) and then to c5 (9...c5) Somehow, the player Herr managed to capture the pawn by playing 10.dxc6 after 9...c5, which was accepted by both the player Sarihan and the interface ..(!?!) And the same happened in the game Ducreux, Regis v Sarihan, Sefa FIGCS_CHESS_CLASS_F_000007, this time pawn c was moved twice again (2...c6 and 10...c5) and captured ("of course") by 11. dxc6.. 8()

!!!
!That's wonderful news! Kind regards Elmer

not PGN
Maybe bringing the text-entry move facility closer to the board might be a quick fix (for the player checking the validity of intended move).
Regarding the format of the on-going games, it appears the player's move is copied "as is" directly to the game score (I have just entered "e7-e5", accepted by the interface as "e5", but it was copied as "1...e7-e5" into the PGN score of the on-going game), regards

bug?
Dear Thibault On-going game 49 has "6.Nb5" although both knights (from c3 and d4) could move to b5 (correct is either 6.Ncb5 or 6.Ndb5)
Anyway, the interface (or the player Ghisi) moved the knight from c3 (more obvious was to move the knight from d4, according to theory at least) and, as a result, the move 7...e5 won a piece..(can't see a post from the concerned players so it could have been played as intended, but the "Nb5" needs correction for sure)
Elmer Valderrama (2006-04-20 15:38:29)
o.k.
OK, thank you!

search by ECO code
Wonderful feature to have all on-going games available just one click away (an old request to Reimund @chessfriend). Even more interesting to be able to search games by player name. Now would it be too much to ask for a search by ECO? --similar games would be identified in a second, a good thing; and information for choosing different variations would be available..
Elmer Valderrama (2006-04-18 23:15:46)
30 d max
I agree with Glen, 'resign' is the hardest word, and some prefer the server (or the time control rules) _gradually_ pronounce it.. 30 days max, with time doubled at move 10th + optional leave of 30 days would be more than reasonable to me.
