Promotes when a pawn reaches the opponent's back rank and is replaced at once by another piece of the same colour. White promotes on the eighth rank; Black promotes on the first rank.

The new piece may be a queen, rook, bishop or knight. In almost every case a player chooses the queen, an action often called queening. The replacement happens as part of the same move, so the pawn disappears and the chosen piece appears on the promotion square instantly.

Although the queen is strongest, there are positions in which promoting to a rook, bishop or knight is better. These choices are called underpromotions and usually arise when a queen would produce stalemate or allow an immediate capture that loses the game.

Promotion turns a passed pawn into a decisive advantage. Because the new piece appears with its full movement rights, a single successful promotion often decides the result at club level.

  • Back Rank — The back rank is the first rank for White or eighth for Black, where each king starts and often remains after castling, leaving it vulnerable to mate when its own pieces block all escape squares.
  • Bishop — A bishop is a chess piece that moves any number of unoccupied squares diagonally and remains on squares of one color for the entire game.
  • Capture — Capture is the act of moving your piece onto a square occupied by an opponent's piece and removing that piece from the board.
  • Castling — Castling moves the king two squares toward a rook, which then jumps to the square the king crossed, provided both pieces are unmoved, the path is clear, and the king neither starts in check nor passes through or lands on an attacked square.
  • Checkmate — Checkmate ends the game when a king is in check and has no legal way to escape by moving, capturing the attacker, or blocking the attack.

  • Babson Task — A Babson Task is a chess problem in which White must reply to each of Black’s four possible pawn promotions by promoting to the same piece to deliver mate.
  • Bishop Of The Wrong Color — A bishop of the wrong color cannot control the promotion square of its passed pawn, typically allowing the defending king to draw a king-and-bishop versus king-and-rook-pawn ending by occupying the promotion corner.
  • Building A Bridge — Building a bridge is a rook-endgame technique, seen in the Lucena position, where the attacking rook moves beside its king to block lateral checks and let the king escort a seventh-rank passed pawn to promotion.
  • Crazyhouse — Crazyhouse is a chess variant in which captured pieces can immediately be dropped back onto the board as the capturer's own pieces, following standard movement rules.
  • Endgame — The endgame is the final phase of a chess game after most pieces have been traded, when play centers on pawn promotion and delivering checkmate with the remaining forces.
  • Excelsior — Excelsior is a chess problem theme in which a single pawn advances from its starting square through successive moves to promotion, typically enabling a surprising mate.
  • Lucena Position — The Lucena position is a winning rook-and-pawn versus rook endgame in which the stronger side builds a bridge with its rook to shield the king from checks and promote the pawn.
  • Opposition — Opposition occurs when two kings face each other on the same rank or file with one square between them, so that the player whose turn it is to move must give way and allow the opponent’s king to advance.
  • Passed Pawn — A passed pawn is one whose advance to promotion cannot be blocked or captured by opposing pawns on the same file or either adjacent file ahead of it.
  • Pawn — Pawns are the eight weakest units per side, advancing only forward one square at a time or two from the starting rank while capturing diagonally ahead, unable to retreat, and promoting if they reach the eighth rank.
  • Philidor Position — The Philidor Position is a fundamental defensive resource in rook-and-pawn endgames in which the defending rook controls the third rank to cut off the attacking king while the defending king remains in front of the passed pawn to block its advance.
  • Threat — A threat is a move or plan that would win material, deliver check, or gain another advantage if the opponent does not prevent it on their next turn.
  • Zugzwang — A position in which every legal move by the player to move worsens their standing, as passing is not permitted.
