In my opinion where many checks there many repetitions and there TT
is more important. After small investigation I discover my program
at ply 13,14 see many really deep checkmates.

I will try explain in this weekend why my program see it.
On depth 10 my program see line
1.Nc6+ Kb7 2.Na5+ Kb6 3.Bf2+ Kxa5
4.e8Q Nc7+ 5.Kd6 Nxe8
6.Kc5 d2 7.Bd4 d1N
8.Be5
in normal search
but I will try find other moves in qsearch and by hashcode and deeper.
