Re: Komodo Dragon vs IM Andras Toth knight odds match.

Larry have you done any study about how much each piece/pawn(with file) odds are worth based on all the handicap matches Komodo played? Well, it's hard to do a rigorous study since opponents and time limits are constantly changing, as well as the version of Komodo being used, but i have some genera...

The computers are assumed to have only a...

Re: Komodo Dragon vs IM Andras Toth knight odds match.

Chess engine authors are way too arrogant when they claim that their program is better than Kasparov or better than Magnus Carlsen because it's obviously just a marketing lie. Kasparov is still at least 200 elo stronger than Komodo dragon 2. Even Komodo Dragon 5 still doesn't stand a chance against...

Re: what is wrong with Komodo Dragon 2 here?

I get Qxf5 on any depth, even one ply. It's hard to fix a nonreproducible mistake. I never observe blunders like this. Please check this position 3r4/3rk1p1/2p1pnp1/2P1KpP1/ppBP3R/3R2P1/PP3P2/8 w - - 2 36 This one can be reproduced if you give 256h no multipv maybe just 1 core though you can see it...

Komodo Dragon vs IM Andras Toth knight odds match.

On June 19 and 20 on chess.com, IM Andras Toth (FIDE 2377, born 1981) will play a six game match with Komodo Dragon giving him knight odds in the now standard Rapid time control of 15' + 10", on chess.com. Since he is in Australia and I'm in the U.S., scheduling was a bit difficult, but we settled o...

Re: what is wrong with Komodo Dragon 2 here?

I had noticed previously that Dragon 2 seemed a bit weaker than dragon 1 and so I started a gauntlet match with KD1 and KD 2 against SF13_noNN. Note this position Dragon 2 has a winning advantage but then it plays Qxf3?? 3r3k/1b3qp1/1p5p/pP1n1p1P/P2P2P1/3Q1p1K/3B1P2/1B4R1 w - - 0 43 I have never se...

Re: My conclusion after playing Vs Top Engines with Rook Odds

It all depends on time limit, but at standard Rapid (15' + 10"), somewhere around 2000 elo is probably enough to win a rook odds match from any engine. Looks like our next official human match will be knight odds (with Armageddon rule) vs. IM Andras Toth (2377 FIDE, age 40) June 19 and 20. We have ...
