[D]8/1p1b2k1/p1p1p1p1/2P1P2p/1P3P1P/P2B4/5K2/8 w - - 0 1
This position is from Baslavsky-Kondratiev 1947 (slightly modified)
The white bishop can aim at 5 of the opponents pawns. The white king
threatens to sneak in at the upper North-West corner - a5,b6,c7.
The black bishop looks just like another pawn. The game went like this:
1.Ke3 Kf7 2.Kd4 Be8 3.Kc3 Ke7 4.Kb3 Kd8 5.Ka4 Kc7 6.Ka5 Bf7 (Black cannot
allow Kb6 and is reduced to waiting moves with his bishop)
7.Bc4! Bg8 8.a4 Bf7 9.b5 axb5 10.axb5 Bg8 (if 10.-cxb5 11.Bxb5 Bg8 12.Be8)
11.b6+ (From now on black has to constantly guard himself against Ba6,
which gives white free hands on the king's flank.)
11.-Kd8 12.Kb4 Bf7 13.Kc3 Kd7 14.Kd4 Kd8 15.Ke3 Kd7 16.f5! gxf5 17.Kf4 Bg6
18.Kg5 Be8 19.Kf6 f4 20.Be2 and wins.
Test1: The above position. It's won for white and your program should
show a high +score for white.
Test2: Exchange the good white Bd3 to the more ugly Bc3. This position
is now a draw and your program should show close to 0.00.
The new position below:
[D]8/1p1b2k1/p1p1p1p1/2P1P2p/1P3P1P/P1B5/5K2/8 w - - 0 1
