Re: Chess solved?

yep chess is a draw in the past i posted some arguments from Zermelo, that it there's no winning strategy (for such games as chess) then it's a draw. And we now know there's no fundamental opening advantage possible for White. ofcourse, in sharp lines, it's sometimes difficult to defend for Black, e...

Re: Chess Fonts

like Norlandia, also like the royal pieces,
especially the 'gold' but depending on background (square colors) i guess;
how to get them working in a chess program as winboard, no idea :)
(years ago fiddled a bit with some piece sets, but usually
came back to the usual stuff as Leipzig or so)

Re: Marcel van Kervinck

sad to hear he's gone (so soon, approx 15 yrs younger than me). Knew him via the (Dutch) CSVN, some 20 yrs ago or so he had given me permission to use his Mscp(1.4); it's apparently still hosted here: https://marcelk.net/mscp/ But not there for long anymore, i suspect (his program(s) Rookie(C), Blik...

Re: Is this English opening a win for white?

well i won't comment in detail coz then i betray my secrets :) (still playing in ICCF correspondence chess, although it has become some sort of an opening lottery and CPU/Gpu engine power game) 1.c4 b6? 2.d4 e6 now i suggest 3.e4! instead of a3 but whether 1... b6 is refuted i leave to you. Sometime...

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). ...
