Endgame study
Chess Endgames
Published Updated
Endgame study has two parts. Some positions have an exact result and a method you can learn; others demand judgement about activity, king position and pawn structure. This guide keeps those two kinds of knowledge separate, then shows how they meet over the board.

Why the endgame rewards study most
With fewer pieces on the board, a move can often be tested against a concrete result. That makes reference positions such as Lucena and Philidor useful. Principles still need their conditions, however: a king in front of a pawn does not always win, and a rook does not belong behind a passed pawn in every tactical position. Learn the reference, understand why it works, then compare the position in your game with it.
The order to learn them
Start with the smallest positions, where the result is easiest to verify. Add practical principles only after the exact foundations are clear.
- Basic checkmates — king & queen, king & rook, two bishops, and the hardest, the bishop & knight mate.
- Pawn endings — the opposition, king and pawn vs king, the rule of the square, and triangulation and reserve tempi.
- Rook endings — the Lucena (winning) and Philidor (drawing) positions, and the guiding principles.
- Special material — queen vs a pawn on the seventh, opposite-coloured bishops, and the wrong bishop with a rook’s pawn.
Two ideas sit under everything
Tempi and entry squares. In pawn endings, identify the squares the king must reach and ask which side benefits from having the move. Opposition, triangulation and spare pawn moves are different ways of answering that question.
Activity and restriction. In piece endings, count what each piece can do: checks, attacks, entry squares and ways to restrict the opposing king. A pawn can be returned; a permanently passive rook is harder to repair.
Try the key position
Know the draw rules too
Technique sits inside the Laws of Chess. A player may claim under the fifty-move rule when the required sequence has elapsed without a pawn move or capture; stalemate ends the game immediately. Repetition and dead positions can matter too. In a tournament, follow the event’s claim procedure rather than relying on an informal description.
How the exact claims were checked
Every FEN in this chapter was loaded with chess.js to check legality. Positions containing no more than seven men were queried against Syzygy tablebases on 13 July 2026, including the side to move and the critical moves named in the text. A tablebase result assumes best play; it confirms win, draw or loss from that position, not that a short verbal rule covers every related position. See the site’s methodology and limits.
