Happy new year too Vlad! This one is a good start for the year, so I managed to make a fast 32-bit Intel compile for you - JA style :wink: !!!

I will try 64-bit if Greko benefits from it later! I hope you allow. Thanks.

I just noticed a slight improvement when compiled on 64-bit. Here is the ICC10.1 64 bit compile.

Thank you Denis!

I will test your build and probably incude it in distributive pack (may I?)
I also plan to modify GreKo's move generator, to make it more bitboardish and 64-bit friendly.

You're welcome. I'm hoping for the best in your tests Vlad. But I hope Jim makes a better 64-bit compile as I haven't fully mastered speed compiling in this area.
