Pharoon is broken it would seem. It plays a move that instantly
draws, when it could play a move that leaves it up material. This
looks more like a bug than anything else... you could try other
positions that are similar to see if it behaves in the same way or
if it _really_ is statically evaluating this as a dead draw.
