Gull 2.1 x64 - Gauntlet Matches 100 Rounds

Gull 2.1 x64 by +Vadim Demichev. aka ThinkingALot was released last June 18, 2013.  It was originally derived from Ivanhoe 63 and 46 but the latest version doesn't seem to show similarities.   The source code is monolithic which includes everything in just one file and the resulting optimized executable is just 251KB, very small compared to the modern Ippolit/Ivanhoes. There are no Robbobases, Montecarlo, Yusuf Multicore and Yakov chart  which are unique in Ippolit/Ivanhoes.

Gull 2.1 scored 52.81% with 836 wins, 684 losses and 1180 draws in the 100 round gauntlet tournament against the 27 strongest computer chess engines. It gained 82 ELO points from the previous Gull R375 version which put it in the 13th rank of the Top 100 Chess Engines list as of June 23, 2013.
