Stockfish 130801 x64 - Gauntlet Matches 100 Rounds

The latest Stockfish 130801 development version by +Marco Costalba+Joona Kiiski and +Tord Romstad was released last August 1, 2013.

In the 100 round gauntlet matches against the strongest chess engines, Stockfish 130801 scored 63.10% with 827 wins, 303 losses and 870 draws. It defeated all the best chess engines including Houdini 3 Pro, but still in the second rankings overall in the ELO rating list. Stockfish 130801 got an ELO rating of 3151 which is 20 points greater than the previous tested version. The older version 130525 was retired and traces of it vanished, so that it will not pollute the new rating list with so many development versions.
