Re: chess.com personality bots research

Hi guys I've been researching several general questions related to chess.com personality bots. 1. Does engine run on front or back end? 2. What engine are they built on top of? 3. What settings were used to tune personalities? 4. How interesting to play with them? Answering first question was proba...

Re: Evaluation of moves from World Championship Games

I tried anlyzing the games from wch games, something similar done by Guid and Bratko using Crafty at fixed depth. I think they did another analysis later with stronger engine. I used Stockfish 13 dev 2020-12-14 using a movetime of 5s per position on 4 cores with i7-2600K. Analysis starts at move 12...

Re: KomodoDragon brilliancy Ruy Lopez - Marshall! A marshall reborn?

ok I just checked in my database of Human-Human GM games, 17...Nf4! move is not found, maybe this is a Novelty by engines. Even SF 12 cannot consider this move (17...Nf4!!) . I wonder if KomodoDragon is NNUE or pure NN similar to Lc0, because this is a very different move which is a bit difficult f...

Re: The 1 hour CCR test by Kaufman/position 22

r3kb1r/pp1n1ppp/1q2p3/n2p4/3P1Bb1/2PB1N2/PPQ2PPP/RN2K2R w KQkq - I never understood this one.

Re: You want to see why human can NOT compete vs engines in Bullet Games?

I checked games of both Fischer and Carlsen at or near their peak. Playing both classical and blitz time controls. Carlsen blitz results. Carlsen Magnus: 57/14/28/25/29/57/28/24/6/65/40/79/10/28/16/21/30/15/16/0 => Average=0.31 Fischer blitz results. Fischer Robert James: 86/101/31/32/44/37/23/24/3...
