The fact that shredder stopped to calculate at depth 9 when it played the
blunder 20...Nc6(I think that 20...Ng6 is better inspite of the fact that white
can reply 21.Nxf7) when it got depthes 11-13 for the rest of the move seems
strange.
I wonder if the reason is a bug in shredder4's time allocation or bug in the
autoplayer.
I have no problem with 36 seconds of calculating if the opponent move was
expected by pondering but in this case I expect shredder to get similiar depth
to other moves.
