Around 2002, Fide went back to the strict 50 move rule after experimenting with higher draw move limits. There was always a draw that took more moves than the Fide draw move limit. The current record is 517 moves. The history is in the link. https://en.wikipedia.org/wiki/Fifty-move_rule However in 2...

I concur that the 50-move rule has to be invoked by the player having the move. And once the checkmate has occurred, the game was ended, depriving the checkmated player of claiming a 50-move draw, 9.3 The game is drawn, upon a correct claim by a player having the move, if: he writes his move, which ...

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.

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?

Hi Graham, Found this one in 40/40. I like the checkmate. -Norm [Event "CCRL 40/40"] [Site "CCRL"] [Date "2015.12.23"] [Round "490.1.931"] [White "Ecce 1.0 (rev. 508) 64-bit"] [Black "Clarabit 1.00 64-bit"] [Result "1/2-1/2"] [ECO "B10"] [Opening "Caro-Kann defence"] [PlyCount "137"] [WhiteE...

So you can added your complete files on my site and you have enough space and you can very easy upload your pag...

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

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...

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...
