What about 73.f4 Kf5 74.Kg3
Crafty with part of the 5 piece tablebases(not including the KBP vs KP) failed
high on 74.Kg3 after a few minutes and the score get up every iteration(the
score is +5.96 at the end of iteration 27.
The idea is 74...Ke4 75.Bb6 Kf5 76.Bd8 Ke4 77.Bc7 Kf5 78.Kh4 Kf6 79.Bb8 Kf5
80.Be5 when black is in zunzwang.
