800 10-sec games: RobboLito - IvanHoe - Stockfish

[PawnStormZ]

         This match was basically to test if the new JA 2.2.2 sse4.2 "Intel" compile would no longer lose on time.  Well, in its 536 games there were 8 losses on time by Stockfish.  I do not know if that (1.5%) would be considered good or bad.  I guess there is still at least a small problem since neither of the others had any time losses.
 
           The time-control was game in 10 seconds plus 1 second per move on Intel core I7 920 at 2.66GHz using 4 cores HT off; Win 7 64 Home Premium; 6G RAM; pc doing nothing but the match while a game is being played.

           Each engine used its default settings; no large pages; no end-game tablebases; 512 hash each; 4 cores each; ponder off.  The openings are played using random choices from the "top200.pgn" created by Sedat Canbaz as part of his "perfect_2011" opening book; each opening is played as Black and White by each engine.
 
           The below results are adjusted to change 5 of the 8 losses (3 v Robbo; 2 v Ivan) from losses to draws based on the evals of the final positions.  The original result remains in the pgn which can be downloaded below.
 
           The surprise for me was that Stockfish defeated both Ivanhoe and RobboLito in their head-to-head matches, and came a close 2nd overall in these super-fast games; RobboLito beating IvanHoe was not expected either.

Pal, I am not trying to create a problem for you where there isn't one. Nothing about these results surprise me, however. Though 9.46h is the latest version, it is not nearly the strongest "46 version". And not even close to the strongest 46h compile. There are a half dozen "Ivanhoe 47" versions stronger than it. And RobboLito 0.10 is definitely stronger than Stockfish 2.2.2- so your results are "dead-on" accurate. The problem is the Ivanhoe version, not your testing.


Best,
