Komodo 1339 64-bit 8CPU v Stockfish 221214 64-bit 8CPU Match

[fenchel]

GAME 41 - Stockfish completes a hat-trick with its third successive win. After there was seemingly nothing to be gained on the queenside, Stockfish again turned its attention to the kingside, slowly ratcheting up the pressure. Once Komodo was tied to defence there, the Stockfish pawns on the queenside hammered home the advantage. With the match score now at 8-4 to Stockfish, Komodo now needs a miracle.

Exciting stuff, many thanks to you for the commentary, and to Ray for running this.

Comparing this and your previous tournament to TCEC, it seems the main things distinguishing SF and K are (a) 16 core play, (b) endgame play (with/without TB), (c) imbalance eval.

(Of course, small sample blah blah.)

[Graham Banks]

GAME 49 - this Stockfish is the strongest kingside bully I've ever seen. In this game, it again wins with an attack on the kingside, not achieving mate, but a decisive material advantage. Stockfish now leads the match 9-4.

[Modern Times]

Exciting stuff, many thanks to you for the commentary, and to Ray for running this.

Comparing this and your previous tournament to TCEC, it seems the main things distinguishing SF and K are (a) 16 core play, (b) endgame play (with/without TB), (c) imbalance eval.

(Of course, small sample blah blah.)

I do find it odd that tablebases were not used in the TCEC final. It is the de-facto world championship, showcasing the two top engines at their very best. Sure leave them out in some of the intermediate rounds to satisfy some people's curiosity, but not the final. Did it affect the result ? Who knows.

[Modern Times]

Stockfish takes the spoils with a +9 =37 -4 scoreline.

I must say that I didn't expect that. A strong result for Stockfish.

Stockfish won your previous 8-core battle over Komodo, and I thought that was maybe just a bit of luck, but it seems not.

[Leto]

Yes the explanation for the difference in result between this match and the recent TCEC final is most likely that TCEC had no TB usage.

I'm a correspondence chess player and I would never dare play the ending phase without TB, so I do think running all rounds of TCEC without TB was silly. At the time control TCEC uses TBs are a must in my opinion.

Silly, or downright stupid ???

With TB the draw rate would be +10% - +15%.

Some engines are much stronger in the endgame than another engines.
With TB they would be ~equal.


It was right to play without TB.

[M ANSARI]

I think in TCEC the main reason Komodo beat SF was not due to EGTB's but rather due to the fact that at LTC Komodo seems to scale better. Also it is possible that given more time Komodo simply has more time to work out the tactics that SF throws at it. There were a few games in TCEC where it seemed that SF was going to tactically blow Komodo out of the water, but somehow Komodo managed to find incredible defensive resources that saved the game and in some cases reversed the result. It just seems that SF strength is tactics while Komodo is more of a positional "squeeze" player ... SF can go deep in a position very very quickly and that can be lethal even against a very strong positional player. All it takes is to see a tactical shot one ply deeper and that is enough advantage to win a game with any of these powerful engines. But given enough think time on strong hardware, Komodo seems more than capable of blunting any tactical fireworks.
