This is one of Averbakh's positions from 1954.
It's a typical winning position in a good versus bad bishop ending.
The black pawns on h5, f5, d5 and a6 are vulnerable and curtail the
movements of the black bishop. To seal black's fate, all white need to do
is lose a move. That is - repeat the initial position with black to move.
This may be accomplished as follows:
1.Be2 Be8 [1.-Bg6 2.Bd3 Bh7 3.Bf1 leads to instant zugzwang, be it after
3.-Bg6 4.Bg2 Bf7 5.Bf3 or after 3.-Bg8 4.Be2 Bf7 5.Bf3]
2.Bd3 Bg6 3.Bc2 Bh7 4.Bb3! Bg8 5.Bd1 Bf7 6.Bf3! and so on
Test: The above position is won for white so your program should be able
to win it. The evals should differ distinctly between white and black.
