100 long games Rybka 4 vs Houdini 1.5

[IWB]

Hallo all,

A few weeks ago I made a test of 100 long games (Game/60min) with Rybka 4 and Houdini 1.03a.

This is the Thread about it: http://www.talkchess.com/forum/viewtopi ... ka+houdini

I repeated the same test with Houdini 1.5. Unfortunately I made a small mistake and set the engine "just" to 256 MB while the original test was done with 1GB. As I recognized this too late I will stick with the result.

Conditions:

GUI: Shredder Classic
CPU: AMD Phenom II 6 core @ 3.275 GHz
Threads: 3(!) (aprox. 4 cores on a Q6600 @ 2.66 GHz)
Hash: 256MB each engine
Opening Positions: FQ 50 Position set
Colours: changing, every engine has to play White and Black, 100 games overall
Time control: 60 minutes per game/each side, played on 5 equal computers.
Ponder: ON (of course, I play real matches!)
Tablebases: 4 piece Nalimov and GTB
Ettiquette: ON (three consecutive 0.00 evals of both engines is a draw, 3 times in a row +/- 5.xx of the loosing engines is a loss!)

Result: + 32,= 51,- 17 in favor for Houdini 1.5

Have fun
