At first glance your alpha-beta implementation looks fine.
You mention that there's something wrong with it, but don't mention what is actually wrong. Can you please describe in more detail what the problem appears to be?


Well it plays incredibly weak!
And it is enormously slow. It takes an hour to reach 7 plies. So I thought maybe there's something wrong with cutoffs

The evaluation routine returns -10000/+10000 in such case.
