2   Houdini 1.03a w32 2_CPU 0½01½½  2.5/6

Next time, without tablebases:




1   Deep Rybka 4 w32        ½½1½½½  3.5/6
2   Houdini 1.03a w32 2_CPU ½½0½½½  2.5/6
10 games maybe not sufficient, but it seems to me that Rybka 4 is stronger in long time control.
In these games i see that Houdini 1.03a has a bad time management and don't use it's time. For example while Rybka has 38 seconds to think(in the middle of game), Houdini has more than 4 minutes! It is strange that such very strong engine hasn't good time management!
I should run some different tests.
However Rybka 4 is stronger in these games.
good luck
