Re: Crafty 25.0 Release (Fine 70 problem?)

But your output points to another possibility. Could you try it with a crafty.rc file, but without TBs? I do not have any TBs that Crafty supports. jm The result is the same, only the output is funny: always the same time for a lot of depths: Well, all I can say at this point is "thank God it's not...

Re: Opening ideas for TCEC 9

There have been discussions about how to make TCEC 9's superfinal more interesting than TCEC8's, and an opening exit eval of about .80 has been suggested by Kai Laskos as ideal. I don't think this is sufficient given that we want sth like an equal number of wins and draws. Or to put it a little mor...

Re: Congratulations to Komodo team for winning TCEC

Only few games remaining but even if Komodo loses all remaining games it will still win TCEC. Congrats to all that worked on Komodo and a really impressive showing. Komodo has shown superiority in evaluation accuracy, and to a chess player that is one of the most useful tools for analysis ... espec...

Re: Komodo strikes first at the TCEC Superfinal

It seems there is mostly one evalutation feature where both engines tend to disagree significantly: knight outposts.

Komodo loves them and evaluates them higher than Stockfish does. And this has worked very well so far.

Re: YAT - Yet another tournament

I suggest including two engines/entities; 1.) Stockfish 0x112015 running with no book. This is interesting in two ways: a.) Potentially one of the competitors could try and cook a win against it. This is very difficult but doeable in principle, and it might be fun to look at the game. b.) It also se...

Re: Knight odds match

[quote="lkaufman" I have pointed out before that for some reason Komodo is able to give surprisingly large handicaps to very strong unrelated engines, but it has trouble giving handicaps to weaker versions of itself or to itself with much less time. My theory is that when two engines have widely dif...

Re: Knight odds match

These odd matches are interesting and incredibly hard to judge IMHO. The rating you give for the opponent is pretty close to what I could personally do in my best years, and I am sure that the best I could ever have got is a lucky draw given reasonable settings for the engine. The FM player shouldn'...

Re: Komodo blunder

Got the first 24.1 game in progress. By move 8, crafty as black, has the eval at 0.0 already, stockfish has traded one queen for one knight and one black pawn. Not looking good for white at all. Maybe you can post one of your games with the search depth and scores? Might get some hint as to what is...

Re: Komodo blunder

This is pretty interesting. I played another game with changed colours and same settings in the meantime: [Event "?"] [Site "?"] [Date "2015.09.18"] [Round "?"] [White "Crafty 24.1"] [WhiteElo ""] [Black "unknown"] [BlackElo ""] [Result "0-1"] [FEN "1nnnknn1/3ppp2/2n2n2/8/8/8/3PPP2/1Q1QK1Q1 w - -"] ...

Time control was game in 1 hour aka 60 minutes with 10 seconds increment per move.
