Houdini 2.0 x64 chess960 testing

[Ray]

This is well under way.

First result:

Houdini 2.0 x64 vs Critter 1.2 = 63.0 - 37.0

Incredible performance against the existing number 1 engine. I could not believe what I was seeing

Further results to come, and by the looks of it they are just as impressive as the one above

[Ray]

Some more results:

Houdini 2.0 x64 vs Stockfish 2.1.1 = 63.0 - 37.0
Houdini 2.0 x64 vs Naum 4.2 x64 = 82.5 - 17.5
Houdini 2.0 x64 vs Hiarcs 13.2 = 88.0 - 12.0

Matches against Spike 1.4, Rybka 4.1 and Shredder 12 will finish in a few hours

So far Houdini looks like this. Balance of the games and a proper web site update will be within 12hrs from now
