I only did a few runs and found it takes SF7 up to 20 minutes to reach the = eval, whereas recent dev builds (June 21 and later) find the draw in a minute and a half or quicker.

I tried the same version as Andreas (160618) and it found the draw at d=56 (log at bottom of post). A couple of subsequent runs failed to do that even at d>60. SMP luck?

In all cases Kc6 was found very quickly, and stayed in the PV throughout. Andreas' case is pretty odd indeed.

Code: Select all
