King and Pawn Endgames: Complete Guide

The most important concept in K+P endgames: opposition. When two kings stand on the same file, rank, or diagonal with one square between them, the player who does NOT have the move has the opposition. The opposition gives your king the ability to outflank the opponent's king and reach critical squares.

Key types: Direct opposition (one square apart), distant opposition (multiple squares apart), and diagonal opposition (on a diagonal).

Every pawn has key squares, squares in front of the pawn that, if the king reaches them, guarantee promotion. For a pawn on e4: the key squares are d6, e6, and f6. If White's king reaches any of these squares with the opposition, the pawn promotes. The Rule of the Square determines whether a king can catch a passed pawn.

• Triangulation: The king makes three moves to end up one square away, transferring the move to the opponent. Essential for gaining the opposition when direct opposition isn't available.
• Shouldering: Using the king to physically block the opponent's king from reaching a key square.
• Corresponding squares: An advanced concept for complex K+P endgames where multiple key squares interact.
