K + P Opposition: chess endgame

Use your king to contest the other king’s advance.

With one square between kings on the same file or rank, the side not to move holds the direct opposition. This can help a king gain entry or block the other king. Whether it wins depends on the pawns, available moves and target squares.

• Identify which side moves next.
• Check pawn moves that change the timing.
• Use opposition to reach a useful square, not as an end in itself.
