Re: Wanted: Programmer for a small EPD tool...

in addition, i'm also willing to send the sources to another (chess) programmer provided he/she's willing to look at it seriously and use the (freely availabe) Borland C++ builder (BCB) 1. package with which it was made (in other words, going 'open source'). NB the later version Bb43 is more advance...

Re: Wanted: Programmer for a small EPD tool...

it already exists (although not with all the options you want), namely an old (and free) version of bookbuilder (bb36c) which you can download (as part of a package with a newer bb) here: [b]http://superchess.blogspot.com/[/b] Nb the latest bb43 (with opening names and crafty analysis) is a one week...

Re: Tool to minimax pgn games

what do you want to minimax ? the engine score at the cutoff eg. ply 25, (or the game result ?). As for using moves played at least two times, the old version of bookbuilder (3.5) has this feature (compress book). For the rest , BB35 can cutoff (when loading in pgn's) at an arbitrary ply depth, eg. ...

Re: 128 CPU Stockfish Cluster Comments.

werewolf, that's my hunch as well. If properly calculated, the engines will not go much beyond 4000 i suspect; actually we could make graph, and see/estimate where it might end. (there are some of such graphs, but just from memory i did not see yet a clear asympotical end level; yet 5000 seems too h...

Re: Is the Blackmar-Diemar Gambit playable?

also analyzed this gambit some time ago, with various engines (Gull sometimes gives intesting moves/lines)/ anyway i still believe in 5...c6! as strongest response.. So i wouldn't play it against a computer (if Stockfish with Black gives -0.6 for White in this position, you are already in trouble). ...

Re: Blood in the streets

interesting to see (without engine) Benoni is double edged btw, from such games you can learn. (my Dutch otb rating is only 1590 or so while my last tourn result was 1840, but i'm now CCM, and probably know most about opening theory than most of you); with this experience i intend to go back to my c...

Re: AlphaZero beats AlphaGo Zero, Stockfish, and Elmo

had a quick look, and it confirms my findings in the Infinity Chess Tourn earlier this year, where i could beat stockfish sometimes as 'centaur' (using Houdini 4 and Komodo10 on two comps). Also, the opening book used by Stockfish in this match was weak if i compare it with my own knowledge as corre...

Re: Houdini 6 has been released

So i do think one of the theorems of Zermelo can be applied, at least in a common sense matter. ok, not only Zermelo, i admit. There has been a guy here once who suggested graph theory. Now if i'm correct, Cerebellum already is using some graph methods, rather than pure minimax. Ask Zipproth if Whi...

Re: Houdini 6 has been released

From a mathematical point of view, chess is a finite game and can be trivially solved by application of the minimax algorithm, but I don't believe you can produce a proof that chess is a draw which can be verified within our lifetime. Zermelo's theorem will in any event not be of help in tackling t...
