Thank you very much for your testing.

The 64-bit version seems to be quite decent. On my notebook it is twice as fast as the 32-bit version.

Let's see what improvement can be achieved by the evaluation redesign I'm currently working on.

More games are on the way and I think Kurt 64-bit is even better. I guess a ELO over 2350. Great jump!!
