I still think that it is a waste of time and maybe it is better to keep a global
varaible that tells me if to probe the pawn hash tables  only when make move
does not change the pawn structure.

At the end of makemove after I already decided if to probe or not to probe
I should have
HaveToProbe=0;

In unmakemove I should have
if (pawn structure was changed)
HaveToProbe=1;

When HaveToPtobe=0 in the beginning of makemove
I can probe only when the pawn structure is changed and in other cases I
alwaysprobe in makemove.
