All the engines used single processor. Rybka comtempt set to zero. It is indeed remarkable that rybka performs much better at this setting against stronger engines. But doesn't this also mean it gets unfair advantage to weaker engines?

I've set all engines elo rating as 2600. After the tournament they are like this according to elostat:

1: RobboLito_009_w32 2677
2: RobboLito_0085e4_w32 2641
3: RobboLito_0085gt3_w32 2627
4: RobboLito_0085g3_w32 2627
5: Rybka 3 1-cpu w32 2587
6: Stockfish32 2428

RobboLito_009_w32 looks like an improvement over previous versions, though its not the supposed official version. RobboLito_0085g3 was the winner of my two previous tournaments but I'll have to agree with people who think e4 is just as strong.

I'm running another tournament on a faster hardware with 3/1 time controls with tankist and rybka 32 MP with MP engines using 2x cores. It might be finished tomorrow.
