Conditional chess moves (again)

Messages to the opponent.

On a technical note, I would envision a JavaScript too that would allow:
1. The move
2. Conditional Move Line 1 and response Moves ...
Maybe more than one conditional lines

The whole web transaction, Move + Conditionals + messages are validated client side via the JS.
Then the transaction is re-validated on the server (to stop hacking).
The whole transaction is accepted or not.

Wch Match Tie Break Rules

Here is most examples of my ficgs practice (corr and Advanced chess). This represent a low percentage of my games. These games are food for thought from my own assisted experience against that rule that I call "+1 decisive advantage chess". I believe you could already burn a lot of chapters in ending's book. Most of my games show balanced games until the end, sometime, the "punished guy" could have played another drawing defense, sometimes not, unfairly to me. The game would be more safe, with less sacrifices of piece vs 2 or 3 pawns and things like that because of fearing an ending with king vs king + piece or king vs king + pawn even if the sacrifice was sound and well played. Game 22895 and 84758 I would probably have been punished by the rule in the ending of game 22895 (and my opponent in the other game), and that type of ending in general (piece + pawn up vs piece when the king cannot block the pawn). Game 37122 Shame on me, my advantage in that ending was not sufficient to force my opponent to sacrifice his bishop for my last pawn. This is why I only deserve 0,5!
Game 37920 That king of pawns vs piece + pawn would become lost for the player without the piece, what a way of punish some balanced sacrifices for pawns!
Game 54907 and 20704 That kind of opposite bishop ending would be "lost" for the guy pawnless even if the transition into an inferior but drawn ending was the intention of the "inferior guy".
Game 74870 The ending is perfectly balanced but my opponent couldn't finish the game the way he did because of the rule.
Game 74875 I would have been half-losing in the pawn ending after a nice defense in an interesting unbalanced material line.
Game 74880 the ending knight + h pawn would have been "half losing" for me even if we can't say that I was clearly worse overall.
Game 76734 and 76764 Technichally this game is not directly concerned by the rule but it is very close. I was on the verge of defeat but I have managed to defend stubornely. If he have played well to get a winning position and then the win disapear because of bad play but still finish with a draw, he would get a bonus because he played better overall? The way I managed to defend would not be rewarded?
Game 77809 In this game the whole deep opening line would probably be "half losing" for Black in the ending because of the new rule.
Game 80954 Suddenly it seems that I would have been punished for my defense in the final position.
Game 85106 I did not play specially badly but... I would have been punished for my way of finishing the game!

Deep analysis - can it be improved?

The idea behind deep analysis is to store engine evaluations of chess positions in a permanent way and build an analysis tree out of them. Deep analysis is an improvement over simple engine analysis in two ways:

1) Permanent storage of analysis results makes them reusable. You don't have to analyse the same position from scratch over and over again (which is a waste of valuable CPU resources) rather you can build and improve upon your earlier results.

2) The search is configurable. You have control over which positions are examined and in what way. This gives you freedom to tailor the analyis to your own needs not having to rely on the defaults provided by your engine.

This idea is presented in a revolutionary way in the Deep Rybka Aquarium GUI. However using this framework I have encountered some problems. The lesser one and non lethal one is that draws by repetition are not handled correctly. This is for a reason: moves in the transposition table should be valued in an absolute way (regardless of the line which lead to them) in order to preserve the integrity of the tree. Since Aquarium has no means to incorporate lines, it simply ignores them

My other problem is that though the search is configurable I'm not absolutely certain about what is going on. It is not entirely clear to me exactly which nodes are selected for analysis.

These problems made me to try to come up with a deep analyis program of my own. After several failed attempts finally I have on my hand a solution which is not only capable of performing deep analysis but overcomes some of the difficulties of Interactive Deep Analyis (IDeA) provided by the Aquarium framework.

First I introduced a mechanism that can handle repetitions. In order to achieve this I attribute not one but two scores to each move and re-define the concept of root position already present in IdeA. The first score which I call 'idea' score is the same as presented in IdeA. The second is what I call 'alpha' score is calculated by minimaxing the tree from the root position taking into account repetitions.

Consider the following game:

1. Nf3 Nf6 2. Ng1 Nf8

The value of move 2. ... Nf8 at depth 18 by Houdini 3.0 is -19 centipawns. So the idea score of this move at depth 0 should be -19. Yet 2. ... Nf8 repeats the starting position. Therefore its alpha score with respect to a root equaling the starting position should be 0 centipawn which is exactly what my program calculates for it. ( For the sake of simplicity I don't require threefold repetition, since you would never allow your opponent to repeat a position if you have better ideas. )

So when my programs lists the tree it will present both scores for every move (which in most of the cases are equal of course - therefore this is mostly an aesthetic improvement rather than being a substantial one).

The improvement which I'm most interested in is that having full control of node selection now I have freedom to shape the tree search.

In order to keeps things simple I have only three parameters characterising the search:

1) engine depth
2) move distance (centipawns)
3) search depth

Engine depth means a fixed depth at which each move is analyzed. After long experimenting I have arrived at depth 18 as a good default for Houdini 3.0.

Move distance is a tolerance up to which moves are allowed into the analyis. For each position first the best move is determined. The search for alternative moves is continued until a move is found that has a valuation less than the valuation of the best move by 'move distance' centipawns (it is this 'distance' away from being the best move). The tree is then expanded for moves within 'move distance'.

To compensate for exponential growth of analyzed nodes I use a simple technique: at each ply after ply 1 the move distance is halved. So if the move distance at ply 0 and ply 1 is 20 centipawns, it will be 10 centipawns for ply 2, 5 centipawns for ply 3 and so on. This means that at greater depth less and less moves are allowed per position. So the analysis with greater depth slowly evolves into 'autoplay' rather than 'tree search'.

The other method to reduce exponential growth is the well known beta cut provided by alphabeta search. In order that all candidate moves in the root position and all candidate responses to them get proper values, I only allow beta cuts with ply 2 and deeper.

Once an alphabeta search of certain depth is carried out, the whole tree is mimimaxed out for the root. Now the initial evaluations of the root moves may change. This may make moves which initially fall out of the 'move distance' to become viable. So the search has to be repeated for those moves as well. This has to be done at every ply level.

My iterative search at a certain depth only ends when no new nodes are added by the alphabeta search (the tree is 'settled' for this depth). Only then the program is allowed to deepen the search (this I call 'refined' search).

With engine depth of 18 and move distance of 10 centipawns an average position can be analyzed to depth 10 within a matter of hours. This means a couple of hundred (possibly a couple of thousand) positions are analyzed to depth 18. Depth 10 deep analyis means an ultimate depth of 28 if you take into account that the engine depth is 18.

Whether this method has added ELO value over simple engine search is yet to be tested.

This is Russia :(

EURO: I would like to move from chess to politics. What do you think about the proclamations of Garry Kasparov, do you see the Russian political reality in a similar light?

KRAMNIK: I disagree with him. It seems to me that his political opinions are empty. Garry is too destructive for my liking. According to him, everything in Russia is wrong, Putin did everything wrong. But that is simply not true. I am convinced that if Kasparov wants to be in politics he needs to offer something positive too, something constructive. Even in the field of human rights protection in Russia there are a number of people doing a lot. Apart from criticising, they create something positive too, by helping some people. Garry’s approach to everything is just demagogic and destructive. I disagree with his opinion that the situation in Russia is as critical as he sees it. I go there often, my brother and my parents live there, so I think I have a pretty good insight. If you want to judge the current situation in Russia you must not take single aspects of it out of the general picture. It is the same as judging a position during a chess game – you need to bear in mind an entire chessboard.

Of course Russia is not a democracy on the same level as countries such as Germany or France, but you cannot judge today’s situation without taking in the historical context. Russia had never been a democratic country in the past, so that is why the transition is not easy. Nevertheless, nowadays eighty percent of the Russian population is not forced to fight for their existence, as they had to, some ten, fifteen years ago.

Anand vs. Topalov, world championship

I hope that the whole mess will stop after this WCC match and things will come back to the normal cycle, even if the whole logic behind the cycle seems fuzzy...
I think Vishy will win, but I'm afraid of attempts to repeat the "toiletgate" in any variant. It started already with the transportation issue...

rare files and torrent...

Well it is like looking for some particular rare thing in 2nd hand shops / fleamarket.. -- you keep trying every 2-3 months, you get some 'quite' rare files over time if you are lucky...

The frustrating thing is when you find a torrent but it is inactive - no one is seeding --- then you can post requests in newsgroups for someone to seed, and hope for the best..

For example, I have 25% of audio of a Chomsky-Foucault debate [I have the transcript - it is very interesting!] - 12 other people have the same 25% and waiting for someone to seed! [for the last 2 years]

Engine Use - My Take

The switch from postcard to server chess has been a wonderfully positive experience.

The transition from human chess to silicon chess on the otherhand has left me bored and wondering if there's still a purpose to the game.

Every tournament is the same. The tournament starts with 6 to 10 players. The moves transition out of the opening at lightning speed, then "Fritz and Rybka time" begins. Turn on your favorite engine and there's a >95% probablitity that your opponents' moves mimic the top engines. There are no surprises, nothing interesting, just boring repetition.

Only a few percent of the chess world can outplay the top engines on fast hardware. Human intervention is like adding a drop of water to a bucket of water and thinking you've made a difference. Most matches are one computer versus another computer and the results are predictable: 1-2 wins, 1-2 losses, most of the games drawn.

I don't oppose engine use. There's no way to enforce it, so there's hardly a reason to forbid it. I do question, however, its purpose. It's just as easy and entertaining for me to play against my computer as it is to play your computer ... and I can do it on my timeline not yours.

I played a friendly young man earlier this year in the ICCF. He was vocal and proud of his high rating and good reults. He'd been playing for less than a year. He eventually admitted through our friendly chat that he hardly knew the moves and rules. He had no idea what "en passant" was or the basic theory of the openings. It took everything I had to save my position and earn a draw from him. That game was "my epithany." I made up my mind to take a break and reconsider what CC is all about. Engine use has been a great technical accomplishment, but has it made CC more enjoyable? Not for me. I hope most of you feel differently.

Good luck and good chess to all :-)

Delay / Slow down the games ?

An interesting idea had been submitted here a few months ago to "decrease the pressure" for all players and to slow down the games... (correspondence chess & Go are quite addictive :))

It would consist in delaying the transmission of moves or at least avoiding one can respond to a move immediately after being played.

The server works very well, but I feel there could be irregular peaks of charge in future... More and more tournaments start, faster and faster and that's probably only the beginning.

So what do you think about the "delay" idea ? .. 1 hour would be probably enough to spread out charge over time, but players may expect more or no delay at all !?

transpositions ...

i think manual modifications aren't really efficient to correct the bug of transpositions .... and for instance , in the transposition f4 e5 e4 to e4 e5 f4 , the move 2)e4 can't be annoted , and will receive the annotation of 2)f4 . and another problem , when i search games on a position , for instance on e4 c5 d4 , i can't find my game who begins with d4 c5 e4 ...

e4 e6 d4 f5

The 'Kingston Defence' is characterised by the opening moves:

1.e4 e6
2.d4 f5

It can also be reached after the transposition of moves 1.d4 f5 2.e4 e6 — a form of Staunton Gambit Declined.

The first record of the defence being played is Schiffers-Chigorin, 1880. The first record of a win by Black is the 1892 victory of Elson over Emanuel Lasker. It remains obscure, but has considerable surprise value.

The Kingston Defence shares a weakness with the French Defence — in the form of the constrained queen's bishop -- and a strength with the Dutch Defence — namely the early thrust of the f-pawn, which often supports a knight on e4. (These French and Dutch similarities led to the first, uncomfortable name for the defence: Frutch.) White's decision at move three tends to define the nature of the game that follows.
