Movei(only material) with values 1 3 3 5 9 finds a win of a pawn by Bxf7+ after
10 plies and the score is constant until it complete 15 plies.
If I give it the position after Ne5 then it finds a pawn loss after 13 plies and
2 pawn loss after 15 plies.
Fritz's move (Nb5) also wins material and after Nb5 movei finds a pawn loss
after 12 plies.
