right. right.
but it is 18 searches deep !
in move 20 (that is 12 searches away from Qc7 it feels negative, and in move
21 even morenegative.
how can the program oversee this, when it sees the things different within
12 plies later.

shredder itself changes the score from + into minus within a few moves.
in between there is the fritz-like 0,00.
if shredder itself sees now the weakness, why wasn't it able to see the obvious
move earlier ? it pruned it away-
if the move was wrong, why the score dropping ??
