I agree it's a draw, the black king go to a8 with a classical "bishop can't control the corner" and pawns are pushed as far as possible -> draw : [Event "?"] [Site "?"] [Date "????.??.??"] [Round "?"] [White "New game"] [Black "?"] [Result "*"] [SetUp "1"] [FEN "8/6p1/8/1K4p1/P7/1n6/6k1/6B1 w - - 0 1"] [PlyCount "8"] 1. Bb6 Kf3 2. Kb4 Ke4 3. Kxb3 Kd5 4. a5 Kc6 * [d]8/6p1/1Bk5/P5p1/8/1K6/8/8 w - - 0 5 On February 21, 2006 at 22:44:50, Will Singleton wrote: >On February 21, 2006 at 22:27:37, Will Singleton wrote: > >>On February 21, 2006 at 22:02:42, Jon Dart wrote: >> >>>[D] 8/6p1/8/1K4p1/P7/1n6/6k1/6B1 w - - >>> >>>How long to find Bb6 with a + score?
