Kd2 I get daily emails like this, but please create a position or get one on the board, *whatever*, where your assumption is true, because in the game black can keep it an easy draw. If i play here Kf7 Ke8 Bf5 Kd7 Kc8 then it's dead draw, because of the nature of opposite bishops. With b6 or without b6, it doesn't matter at all! > 60.. Kf5 61. Kc3 Ke4 62. Bf2 Be6 63. >Kb4 Kd5 64.
