Homura_230517_bmi2 playing a match against CyberPagno 3.0 x64:



Attention! The engine does not support GUI books (it has a more special Monte Carlo algorithm implementation). That didn't stop it from beating CyberPagno 3.0 x64 (with its own book) brilliantly:

Very interesting, but apparently there are no builds (no exe) for this engine...

Additional information:
==============

Homura only recognizes "movetime" or "infinite" time controls. To avoid time forfeits they will only be used "Time per move option" (in Adjust Level panel - Arena 3.5.1 GUI). Best 6/10 seconds per move. More time = a much more accurate game.
