How SF managed to trap its own dragon B without even realizing it. This is a curious game where SF didn't realize its Bh8 is dead, useless piece. In informator lingo it would be called (xBh8), and its eval score didn't even show that he is already a piece down. [Event "CCC10 Semifinals (10|3)"] [Sit...

Well, I'll go on record saying that latest Stockfish is insane if it really thinks 2.c4 is 0.85. Maybe Larry is right about some weird scaling happening now. For contrast here's private Stockfish with learning up to some depth 33. The thing with this version is that, if 2.d5 is best, I can show it ...

My opinion on this 2.d5 against Dutch is that this move allows black to equalize quickly. Maybe time to call that 2.d5 move Tsvetkov Attack. But seriously, it was not yet played by very strong players in tournament conditions because it is counterintuitive. Reason why 2.d5 wasn't played, it violates...

Lc0 is very strong about positional openings. The best net to LTC and strong RTX hardware in games and performing the best in my opening test-suite is JHorthos 320x24b bignet J13B.2-136 (built upon late T40 nets). It practically understands in 1 million nodes search all human opening theory built i...

Even more shocking are the two crashes of Stockfish due to a faulty file. One more crash and it's out. The participant authors took a vote on whether or not the SF people should be allowed to replace that file. but because one voted no, it won't happen. Which file of Stockfish was faulty? After man...

I'm not following what you suggesting , but the tree is much bigger with Qxh7. I think Uri is taking the view from the player giving the mate, so the tree is the tree of possible defensive moves. To prove it really is a forced mate, you don't need to look at other moves that are possible for the ma...

Where do I find a list of available Crafty executables anyway?

This is what happens when Lc0 steers the game into a tactical meelee against Stockfish. Nice game between these two.

Sorry, but what's the story behind this game? Regarding the final position, white cannot lose this position as the lone pawn of black can be grabbed by Rook anytime and white holds a draw. Would be nice to know the background story on how White lost this. [ePGN "0.1;DGT LiveChess/2.2-18062500"] [Eve...
