d6, thus Black is defeated because of zugzwang. In the position at right, Black loses immediately. Black, on move, must give way with either bishop or king, allowing White to move e7, winning, or else play the hopeless 1... Bxd6 2. Kxd6. If White is to move in this position, he plays a waiting move such as 1. Kc6, placing Black in the same predicament (1... Ke8 2. Kc7#). More pawns Draws are possible with more pawns. This is an example of a drawing fortress with opposite-colored bishops when three pawns behind. White simply keeps his bishop on the h3 to c8 diagonal. (See Fortress (chess)#Opposite-colored bishops.) Positions with three pawns versus none are wins 90% of the time. Examples from master games Berger vs. Kotlerman In Berger versus Kotlerman, the pawns are separated by two files, but the game was drawn. 1. Ke2 b3 2. Kd1 Kb4 3. Bh7 Ka3 4. Bg6 Kb2 5. Bf7! Ka2 6. Be6 Ka3 7. Bf5! If 7...b2, then 8.Bb1. If Black keeps his king near the b-pawn, then White moves his king. If the king goes to g2 trying to displace the white king, White moves the bishop. Piskov vs. Nunn In this game Black has an inferior position, but he draws by exchanging queens and rooks, giving up two pawns, and reaching a drawn endgame: 37. Bf6 Qh5! 38. Qxh5 gxh5 39. Rxe8+ Bxe8 40. Be7 Bg6 41. Bxc5 Kf7! 42. Bxd4 a6 43. a3 Bd3 44. c5 Bc4 45. d6 Ke6 46. Kf2 Kd7 The blockade has been set up. Black's pawns can be protected by his bishop and White's passed pawns cannot make any progress. The game continued: 47. Kg3 Be6 48. h4 Kc6 49. ½–½ Nunn In this position from Nunn (a slight modification of a simultaneous game), White wins: 1... Be1 2. Kf6! Bh4 3. Kf5 Kd6 4. g3 fxg3 5. Bg2 Kc7 6. Ke5 g4 7. hxg4 and White wins easily by supporting the g-pawn with the king. Black loses because he cannot defend the pawn on g5 with the bishop from d8 or e7. If the black king were on b8, then 1...Ba5 would draw. Sokolov vs. McShane In the game between Ivan Sokolov and Luke McShane, Black discards his pawn and goes for a stalemate defense: 1... c4!? 2. Bxc4 Kf8 3. h5 Ke7 4. Bb3 Kf8 5. f6 Ke8 ½–½ and a draw was
