Re: When can we Expect CCRL to start testing No Castling ?

I remembered when I asked the same question back 15 years or 16 years ago and 3 months later CCRL started testing Chess960(FRC) :roll: Note: I also noticed that in Chess960(FRC) Most top 3 Engines that start with 1.d4 in CCRL out of 64 of the 112 CCRL games White has a a success rate of 75%, How co...

Re: Show me another underpromotion great game !

Mayhem 5.0 underpromotes ( 71. c8=N ) Then sacks the N and went to checkmate KQvkb. :lol: Mayhem has knowledge about these endgames. Very suboptimal play. 71.c8=Q is a mate in 15.

Re: Positions Chess Engines Don't Understand

Hello everyone :) I'm interested in positions (especially problems) that chess engines struggle to understand for various reasons. Perhaps there is a known collection that is used for testing, or perhaps members might know positions that interest them that they would share? Here is an example (Giri...

Re: triskaidekaphobia

There have been many puzzles/compositions designed as single numbers or letters on the board.

Any for number 13?

Funnily enough Chessbase now has an article on his KP studies https://en.chessbase.com/post/study-of-the-month-2021-02 But there is a lot of great background information on this man. Does anyone have FENs for positions in thie CB article before I enter them manual...
