Übrigens ist Crafty meiner Einschätzung nach eine engine, die mit weniger Nullzug arbeitet, als die meisten anderen:

22 Min. auf Quad ist nicht gerade schnell aber immerhin gefunden. Überhaupt ist Crafty für mich eine sehr gründliche engine, irgendwann findet er fast alles, braucht allerdings seine Zeit und oder seine hardware.

Hallo!
Hier einmal Crafty - einmal 32-bit (CB)- einmal 64-bit native Version unter Arena.
Wie man leicht erkennen kann, findet die 64-Bit Version unter Arena die Lösung mehr als doppelt so schnell
bei gleicher Suchtiefe.
