Naum 4.2 x64 - Gauntlet Matches, 100 Rounds

Naum 4.2 x64 by +Alexandar Naumov scored 25.56% with 176 wins, 1056 draws and 568 losses in the 100 round gauntlet matches against the strongest computer chess engines.  The event is Category 32 with average ELO Rating of 3040.  Naum's score was lopsided as it hit the bottom of the field with a big gap in between that is filled by the stronger 32-bit engines in the overall rating list.

One noticeable change is the diluted ELO rating of Houdini 3 each time that there is a new gauntlet added, from a high ELO rating of 3215 down to 3197.
