Re: AlphaZero No Castling Chess

I ran the following test last night. Komodo 13.2.5 (regular mode) vs K2453.00 MCTS (latest dev), with regular K on one thread and MCTS on2, to make them realsonably competitive (regular won by 39 elo). 2 min + 1", White Contempt 75 (maybe I need to rerun it with Contempt 50 in view of your results)...

Re: A Gilden rematch

The announcement Komodo NN can be something similar to a christmas gift from team Komodo. Maybe opt for GPU donation for Komodo NN improvement. Stockfish and Leela relies on voluntary CPU / GPU donation. Maybe this is something to consider. Right now the focus is on how to best combine Komodo with ...

Re: In No castling Chess what Engine would be the King or the best?

@GM Kaufman: I am persuaded by your arguments. Still, I think the basic premise — that the large number of draws at the top level is a problem — is open to question. Many draws are satisfying, well-played games. While I wouldn’t want a WC title to be decided by a rapid or blitz game, there is somet...

Re: A Gilden rematch

White got a strong attack right out of the opening (The Scandinavian 1...d5 is ideal at b1 odds but not so good at g1 odds) and won quite quickly. Final score 3.5 to 1.5 (3 wins for Komodo, 1 win for Gilden, 1 draw). Komodo won all three at g1 odds, but lost 1.5 to 0.5 at b1 odds. Perhaps 1.f4 isn't...

Re: A Gilden rematch

This was the first win by a human master in the last twelve pre-announced knight odds rapid games on chess.com. Komodo failed to obtain any initiative or compensation for the piece, Gilden methodically simplified and won cleanly. [Event "Live Chess - Knight Odds"] [Site "Chess.com"] [Date "2019.17.d...

Re: A Gilden rematch

In this game White developed a strong attack but Gilden found the defense to force Komodo to settle for perpetual check.
