Strelka 5.7 MP x64 - Gauntlet Matches, 100 Rounds

Sorry, I had 3 days Internet outage, so this Strelka gauntlet matches was stuck.

Finally, after some months of speculation, Strelka 5.7 MP beta was available. Strelka is a UCI chess engine authored by Juri Osipov produced last April 11, 2013.  This version appeared in Immortalchess.com which was exclusively promoted by George Speight without supporting evidence that was promptly rebuked by the admin.

Strelka scored 53.42% with 548 wins, 418 losses and 934 draws . It gained 3111 ELO points and number 4 rank in the Top 100 Chess Engines List.
 
Strelka 5.7 is a multiprocessor chess engine but had losses by time forfeit by as much as 50% in my testing environment. To salvage this engine, I used only 1 thread or one CPU for it to be usable and match the same with the opponent if the thread or CPU parameter is available. Therefore, the rating list is somewhat contaminated by this anomaly. If a new stable version will be available, I will immediately remove it, just like I did with the unstable Bouquet 1.7 beta.
