if the knight pawn is not far advanced and the attacking bishop controls its promotion square with a and a central pawn the endgame is a draw If the pawns are separated by three files: With a knight pawn there are drawing chances if the pawn is far advanced With a rook pawn the position is usually won If the pawns are separated by four files The ending is won because the attacking king gets between the pawns. Connected pawns Positions with connected pawns are the most complex case, and the result depends on the and of the pawns and the colors and locations of the bishops. If one of the pawns is a (on the a- or h- file) the position is normally drawn. If the pawns are on the opposite color as the defender's bishop, the defender may be able to blockade the pawns and draw. If both pawns can safely reach the sixth rank, they win unless one is the wrong rook pawn, i.e. the rook pawn that promotes on the square of the same color as the defending bishop. The ideal drawing setup is seen in the diagram at left. Black's king (on a square not of the color of the opposing bishop) and bishop stay two ranks in front of the pawns, with both defending against a pawn advance (here d6 by White) to the same color square as the bishop. The defending bishop must maintain an attack on the pawn on the same color square as itself, so that the attacking king is not allowed to advance. If White the other (unattacked) pawn, Black's bishop itself for both pawns, with a draw. (If the second pawn is protected and advances instead, the position is also a draw.) In the diagram position, Black on move passes (i.e. a waiting move that maintains the attack on the pawn) with 1... Bb8! 2. Ke4 Bc7! 3. Kf5 Bb8! and so on. White cannot make progress: 4. d6+ is met, as always, by 4... Bxd6 5. exd6+ Kxd6 with an immediate draw; 4. e6 gives Black an unbreakable blockade on the dark squares; and White can never prepare for d6+ by playing Kc5 because Black plays ... Bxe5. A similar position with White's pawns on the sixth rank is a win because the black bishop has no room to move and maintain the attack on the pawn on
