Sep-23-09		Artar1: <ajile: Chess has been solved by Rybka. I predict all future games we play against top rated opponents will end in draws.> I'm in the process of putting together an opening repertoire for both White and Black. What I have discovered is that with best play the game leads to a balanced position. That's not to say chess has been solved, for I think the shear number of opening combinations and resulting branches of play make it nearly impossible for us to know all outcomes in advance.

Sep-23-09		Artar1: <g.mueller>: Your example is a prime demonstration of how a computer can make us all look like monkeys when it comes to solving chess problems! But, please excuse my ignorance: doesn't the 50-move rule apply in your example?

Sep-23-09		ontocaustic: chess is only solved if you think it is solved, just come up with a new unsolvable kind of chess then. that's why the world will always have guys like kasparow to carry the torch, and patzers like the world team to pretend, of their own conceit, that they can beat him in a match he wouldn't deign to play.

Sep-23-09		kb2ct: <Artar1: <g.mueller>: doesn't the 50-move rule apply in your example?> Yes the 50 move rule applies. This was also known at the time although 6 man EGTB's weren't there to prove it. The Kasparov game was one of the main motivations behind 6 man EGTB's Post mortem analysis created the first 6 man tablebase. :0)

Sep-24-09		mworld: <ajile: Chess has been solved by Rybka. I predict all future games we play against top rated opponents will end in draws.> i predict when the game gets solved there will be a forced win for white (like checkers) that will be impossible for a human to memorize - and on the way to discovering this forced win will be a long path of draws ahead. Even so, chess should still be a great game amongst us humans and it will suck even more to play against rybka :)

Sep-24-09		lost in space: Lord have mercy with poor Miss Percy!

Sep-24-09		Xenon Oxide: checkers has been solved to be a draw

Sep-24-09		mworld: < Xenon Oxide: checkers has been solved to be a draw > yes you are right! my mistake, i was thinking of the article talking about how no human could actually manage to secure the draw against the computer...which just highlites my main point - that the game is still going to be alive and well if we stick to playing each other. perhaps a better, and more relevant, analogy would have been "the little game of chess" being won by white?

Sep-29-09		kb2ct: A chessfriend just solved 3 X 4 chess 3x4 chess definition: The board is 3 squares wide and 4 squares tall (not the other way around). No two square option for first pawn move, no castling. All possible piece placements and starting moves considered like a miniture Fischer random Suprisingly black wins :0)

Sep-30-09		kormier: naturally <kb2ct>, though black has to play with precision!

Sep-30-09		kb2ct: <kormier:> I misspoke. Black wins the majority of games not wins by force. The solution is done by tablebase The result. Out of 167,303,246,916 possible legal positions 52,048,121,059 are checkmates (31.11%). Out of the remaining 115,255,125,857 non-checkmate positions 48,713,659,039 are wins (for the side to move) (42.27%), 51,946,919,196 are losses (45.07%) and 14,594,547,622 are draws (12.66%). Summing up: Draw is unlikely in 3x4 chess (only 12.66%). Side to move surprisingly has disadvantage: 45.07% chance to lose vs 42.27% chance to win. Longest distance to mate is 43 moves. :0)

Oct-01-09		kormier: ok, then you say it's total=100%(31+28+31+10) approx....., it's sure is nice to know, it lighten my lantern...Tk's, By,by.

Oct-02-09		kormier: <kb2ct> i think i am not right, specially,.....i am trying to understand what is a non- checkmate win or loss? Well, i'm thinking you mean someting so evident in my own language .....tk's by by.

Oct-03-09		kb2ct: <kormier> This might explain it a little better. http://kirr.homeunix.org/chess/3x4-... :0)

Oct-03-09		kormier: Tk's <kb2ct>, i really appreciate, 66.10% for white in a 3x4, next on line might be expecting something like 4x4 chess and 16 digits... lol..... By,by.

Oct-04-09		mworld: interesint, I never knew of 3x3/3x4 chess. Kb2ct you and the link are confusing. Is 3x4 chess solved to be a forced white win, black win, draw, or is it not completely solved? All i see is that every position is documented, but nothing that answers the question that if you start the game from move 1 and play perfectly by the rules what the outcome would be. Also, same question for 3x3 chess.

Oct-05-09		kb2ct: <mworld:> It has been solved. What might be confusing is that there is no standard starting position. It has not been completely verified yet. The following is the longest mate known. http://kirr.homeunix.org/chess/3x4-... :0)

Oct-06-09		mworld: i think i am starting to understand, its more like fischer random...so for some starting positions its a forced white, others a forced black or draw, but the statistics of the starting positions show that most of them favor black?

Oct-06-09		kb2ct: <mworld:> Yes, it is even more random than Fischer Random. Probably more of a mathmatics or programing problem than a chess problem. Its only real value is the thought involved. :0)
