Francois, Here is an offshoot related to your correspondence position in the thread, "Help with Position". The pattern of pawns on the a file lends itself to a neat drawing position. A typical draw position is this: 8/p1k5/P7/2K5/8/8/6B1/8 b - - id "draw"; There is no way to break through for white despite the bishop up. It is similar to the bishop ending with the wrong colored queening square. In this case of course the queening square is the same color as the bishop but white's pawn being advanced to a6 ruins any chance of a victory. Will most programs wrongly eval this as around +3 ? Here are some positions that might be fun to test on computers. Kc6 or Kc7 draws while Kc5 loses: 8/p4p2/Pk3K2/8/8/3B4/8/8 b - - am Kc5; Kxf7 draws but Ke7 wins as the King will reach d8: 8/p4p2/P4K2/2k5/8/3B4/8/8 w - - bm Ke7; I realize that your game was different than the examples above and it would have been a long shot to transpose to them, but I thought it would provide interesting test positions.
