I would not use a computer on this position, it is to deep for them to see how to win this position after Nxb6 in a short amount of time. The eye is sometimes faster then the computer. I thinks this wins. 1. Nxb6 c7xb6 2. Kb3 Kb8 3.Ka4 Kc7 4 Qxa5!! this looks to me to be an easy win for white. No way to stop the pawns and save blacks position.
