I must be missing something. Just because the score was 0.00 for a bunch of moves (8 here), the GUI called it a draw? There could be a lot of play here, and the predicted move wassn't even a repetition. I don't think allowing GUI draws like this is a good testing method. Do we need Danailov to enforce Sofia rules in computer testing?

Looks like the new IvanHoe's are off to a good start..........

4'2"/ i7-940 @ 3.75 /3 cores ea / 512 mb / ponder off / klo openings / R4 default settings , no large pages , using 3-4-5 egtb /IvanHoe using RobboBases , and pawn hash set to 64 / both using default time controls /

IvanHoe 9.57bx64..........55.5..........+28,=55,-17

Rybka 4 SSE42x64..........45.5..........+17,=55,-28

In order to stay competitive , Vas may need to transfer some of that Cloud Rybka Elo back to the 4.1 update...........

What are the best TC settings at 4 min + 2 sec for R4 + IvanHoe ??

What are best TC settings at game/20 mins ??

Thanks.........
