Comments - Another impressive performance by Rykba especially considering Junior
had a 2-1 edge in processing power. I chose time control 3+0 and threads=2 for
Junior to try and simulate a common scenario on playchess.com
where a lot of dual machines play in the engine room. Rybka only supports 1
thread.
Time control - 3min + 0sec
System - Windows x64, 4gb RAM, 2 dual core AMD Opteron 275 (2.2ghz) = 4 total
cores
Interface - Chessbase GUI Fritz 9 Oct 17
Book- Perfect 9.0, option=normal
Hash - 256mb each engine
Ponder - On
Threads - Rybka=1, Deep Junior=2
EGTB- all common 3-4-5, some 6, total about 90gb
Engine Options - default except Deep Junior 9 threads=2
