OpenChess

Here is a tournament I'm running on my computer to determine how strong these top engines really are compared to each other. I will update this in a couple days when it is finished and post the results/pgn. If any engines crash during the tournament the game will be replayed, if they crash multiple times they will be removed from the tournament. The contestants and format is as follows:
Houdini 1.5a
Deep Rybka 4
Fire 1.31
IvanHoe B47cB
Stockfish 2.01
Igorrit_0086v9_x64

Round Robin Carousel
15 pairings, 10 Rounds, 150 Games
Rules: 5 Seconds Per Move
CPU: AMD 965, 3.4GHz Quad-Core 64-bit
Results: TBA

Hardware: AMD Phenom(tm) II X4 965 Processor 3406 MHz with 4.0 GB Memory

First 5 game results:

After 67 Games:


Houdini and Stockfish are fighting over 1st place. Fire has crashed twice so far and might need to be kicked out if it does again as it wastes valuable hours of testing.
