Hash Size: 2,048 MBs
For the first 50 games, the engines chose the openings at random (up to move 10), but they did NOT have to play both White and Black for each opening. For the last 50 games, I chose the openings (up to move 10), and they DID have to play both White and Black for each opening. The score for the first 50 games was a tie. The score for the last 50 games was +2 for Rybka.

From a software perspective, how do you guarantee that an engine's algorithm doesn't appropriate cpu/ram/cache resources in an unfair manner while running alongside the other engine?
well, i don't know how to guarantee it. i did monitor the engines in windows performance monitor--which watches cpu/ram/disk/etc--before running the tournament. they seemed to be switching on and off 100% when it was or wasn't their turn. try it.
Still an impressive performance for a freeware chess engine. It's clearly the engine to use if you cannot afford the latest Deep Rybka, and arguably should be used as an 2nd opinion even with the use of Rybka.
After running this match and watching them grind away at similar positions in games 51-100, I can say I fully agree with the statement that it is faster. better, though? depends on the position.
What would you say is the most interesting game (or games) of all these? Has anyone done an analysis of them?
Were there any novelties by the computers?
most interesting? can't really say. depends on people's preferences, really. there were interesting *moments*, though. some really surprising moves. i can't remember any specific ones right now. i should make a web page for each win, so people can see the games. hmmm... i would love for people to analyze them, do an eco breakdown, etc.
yes. several. i am sorry i can't remember them. i think i will create a web page for each win, so people can watch the games w/o having to cut and paste the PGNs and view them themselves.
The link does not work any more. Any idea where the PGN of these games could be found?
im not able to access the games anymore =(.
could you give another link
