A Gilden rematch

As some of you may recall, a few months ago Komodo MCTS pulled off a stunning 6 to 0 shutout of FM Larry Gilden giving him knight odds (alternating b1 and g1) at 15' + 10", and expressed the desire for a rematch with more time, 30' + 10". Since a couple years earlier he had defeated Komodo 3 to 0 at...

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

Does "no castling chess" have an official variant name? Probably "NCC" because it seems Armageddon will be the last variant named by creative people :mrgreen: How about the Kramnik variant? I am not a big follower of GM Vladimir Kramnik, but he seems to have invented it. I don't mind naming it afte...

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

What is the point of it ? Kramnik basically makes two good points. One is that the castling rule is illogical and arbitrary, and may have been introduced for reasons that make no sense today. The other is that the game is much more interesting when the players have to figure out for themselves how ...

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

Do you believe that it would be Komodo, Stockfish or maybe a version of NN like Fat Fritz or Leela ? https://www.chessbase.in/news/No-Castling-Chess-Vladimir-Kramnik-proposes-an-exciting-variant- The NNs should be relatively weaker at this variant without having been trained on it, although I doubt...

Re: Weakening Komodo 13.2.5...

Humans tend to imitate their opponents, specially time to move, so if an engine plays in 1 second, the human will be encouraged to play in one second, or much faster than they would if the engine took as long as them. This ends being a bad habit, and I've beaten people at 10 minute chess just becau...

Re: Weakening Komodo 13.2.5...

Rebel Decade solved this two decades ago. What the engine can do is checking what move it would have played instantly, but then it continues analyzing paying attention to the time control. When it's its time to move it ignores the extra analysis and makes the instant move anyway. This produces natu...

Re: AlphaZero No Castling Chess

Engines need to know that they're playing armageddon. So they need to be taught playing that mode. I agree, in the same way AlphaZero has been trained to play No Castling Chess, Lc0 must learn No Castling Chess or BNC with draw advantage, while alpha-beta programs must be also modified. A new openi...

Re: Weakening Komodo 13.2.5...

We discussed this when those levels were added, but didn't (yet) implement it. Chess.com chose to have it move instantly (or maybe 0.1" delay, I forget) rather than have a one second delay on their site, so we didn't do this. We could have it delay one second on the download version and not on the c...
