opposition. White's king has reached the sixth rank before the pawn; 6.e6?? Kf8 draws. 6... Kd8 7. Kf7 and White wins. There are several other variations, depending on Black's moves. Example from Maróczy vs. Marshall In this example from Géza Maróczy–Frank Marshall, Monte Carlo 1903, Black to move gets the king in front of the pawn with the opposition: 1... Kg4! 2. Kh2 Kf3 3. Kh3 g4+ 4. Kh2 Kf2! 5. Kh1 Kg3 6. Kg1 Kh3! and the game could continue: 7. Kh1 g3 8. Kg1 g2 . Case 4, all three conditions are met Of course, the ideal situation is when all three conditions are met. In this diagram, if Black is to move all three conditions are met and White wins easily: 1... Kd8 2. Kb7 and the pawn will promote (e.g. 2...Kd7 3.c6+ followed by 4.c7 and 5.c8). If White is to move in this position, then conditions (a) and (c) are met, so White wins: 1. Kd6 Kd8 2. c6 Kc8 3. c7 Kb7 4. Kd7 etc., as above. This emphasizes the importance of getting the king to the sixth rank in front of the pawn. If this configuration is achieved, White wins no matter which side is to move. Exception – rook pawn For a rook pawn, it is possible for Black to draw even if all three conditions are met. In the diagram, all three conditions are satisfied (opposition is satisfied if it is Black's turn) but it is a draw no matter whose move it is. If it is Black to move: 1... Kb8 2. Kb6 Ka8 3. a6 Kb8 4. a7+ Ka8 leads to either stalemate or White giving up the pawn. Or if 1... Kb8 2. Kb5 Ka8 3. Kb6 Kb8 4. a6 Ka8 leads to a draw. If it is White to move: 1. Kb6 Kb8 2. a6 Ka8 3. a7 is stalemate. Or: 1. Kb6 Kb8 2. Kb5 Ka8 3. Kb6 Kb8 4. a6 Ka8 leads to either White giving up the pawn or stalemate. In both cases with White to move or Black to move, all Black needs to do is shuffle between a8 and b8 and White's king can never reach the key square b7 or b8. In the second diagram, it is again a draw no matter whose turn it is. If it is White's turn: 1. Kh8 Kf8 2. h7 Kf7 and this time it
