Up Topic The Rybka Lounge / Computer Chess / Mar del Plata match: SF - Komodo 50-50
- - By Venator (Silver) Date 2017-07-01 07:23
A friend of mine played a match between Stockfish and Komodo 10.4, using my Mar del Plata testsuite. The tempo was "game in 25, plus 2 seconds increment". Both engines used 2 CPU's. The result:

Stockfish_dev - Komodo 10.4  50-50 (+16-16=68)

There were 17 white wins, 7 by SF and 10 by Komodo.
There were 15 black wins, 9 by SF and 6 by Komodo.

Wow! Really entertaining!
I would have expected Stockfish to win by a big margin, because I observed that in a (smaller) match between Sf-dev en K11, in which SF saw sacrifes like ...g3 and Nh7/Ng5/Nxh3+ much earleier than K11 did.

Interestingly, Komodo performed better with white, while Stockfish performed better with black. Still, I couldn't see any difference between the two in this match. Komodo finds g4-g3 pawn sacrifices and piece sacrifices on h3 and/or e4 just as Stockfish does.

I hope someone with big hardware will play a LTC match using this testsuite. Should give a lot of entertaining games.
