Ice 1.0 x64 - Gauntlet Matches 20 Rounds

Ice 1.0 x64 by Thomas Petzke, a UCI chess engine was released last July 7, 2013. In the 20 round gauntlet matches against 20 opponents, it scored 76.75% with 270 wins, 56 losses and 74 draws. Ice 1.0 x64 earned 2573 ELO points with a big 273 ELO points jump from the previous version. However, the big reason for the difference is the use of the 64bit version instead of the 32bit version in the previous rating competition.  This is the first step in upgrading the Owl Rating List to use 64bit versions whenever available to reflect the maximum strength of the chess engine.

  1. Hi, this is not exactly true. The faster 64 bit code contributes only 60 to 70 ELO out of the 270. You can verify that by using the 32 version which will be also much stronger than the previous one. The biggest ELO increase was caused by an rework of the evaluation and careful tuning of the evaluation weights.

    PS.: Thanks for testing it.
