as many stated the problem is not 50...Kc5 but the plan of grabbing the pawn
instead of forcing a passer.

The point is that the program prefers to grab a pawn, instead of swapping it to
get the passer, which is a very bad decision.

Again it is matter of greedyness. I guess that if you try to add some value to
the passed pawns you might get the right play by the engine.
