Re: CCRL 40/40, 40/4 and FRC lists updated (21st January 201

I can visualize a scenario where a checkmate is also a legal draw --> if the checkmating move is the last ply of 50-moves without a capture or pawn move, and the side being checkmated declares a draw. This was not the case here as there was a pawn move as recent as move 63.

Re: The value of endgame tablebases

With 6 pieces on the board how can you be sure it was the Nalimov 5-piece tbs that saw the blunder instead of the engine itself?

Re: Chessbase Mating Pattern Statistics

Addendum: The original mating example also has a symmetry factor. So its multiplicity should be 120.

Re: Chessbase Mating Pattern Statistics

I would like to see a classification system for all the different "types" of checkmates, and stalemates. Similar to the classification for openings. There are several obvious obstacles. First, each "checkmate" can occur with colors reversed, and in many different locations. For example, the original...

Re: Moved "40H" tools/utilities to a new URL

All seems fine now. I have 2 good locations for my 40H site. The previously reported outage at one of the locations only lasted a few hours. Considering that I had to abandon 3 previous locations this year because they stopped working, I am happy with the two I have now. Please bookmark whichever, o...

To say they are unreliable is an understatement.

Fortunately Jesse offered to host the site and while we are in the process of testing it, it does seem to be ok. Try this one:

Re: Moved "40H" tools/utilities to a new URL

Hi, Norm! You can use <my username> at gmail.com I don't know how to make an executable from a java file, all documentation I found says you still need a JVM. However, a .jar should work. I'm interested in bmOpcode mostly to evaluate some positions using stockfish and compare with my chess engine. ...
