A reserve tempo is a spare, harmless move, usually a pawn move, that one side can make without damaging its position, passing the obligation to move across to the opponent. In many [endgames](https://georgelichess.com/glossary/endgame.md) the winner is the player who runs out of useful moves last. A reserve tempo is a move you can afford to burn: a pawn push that weakens nothing, or a rook shuffle that still covers every key [square](https://georgelichess.com/glossary/square.md). The idea matters most when the kings are locked in a standoff, such as the [opposition](https://georgelichess.com/glossary/opposition.md), where whoever moves first must give way. If you hold such a move and your opponent has none, the opponent must give way with the king and yours walks in. Count tempi before committing your king. Ask how many harmless pawn moves each side has, whether a pawn is still on its starting rank and so owns two single steps or a double step, and whether any push would open a new square to the enemy king. A pawn that has already moved once has one fewer spare move than it did before. A typical error is to spend a spare move early, because it looks natural, and then lack it when the kings finally face each other. Another is to forget that the opponent may be counting too, so a plan that works against a bare king fails in the real position. Keep your spare moves in your pocket until the position actually demands them. Also called: spare tempo. ## Example position White to move. The kings are locked beside the c-pawns, and whichever king moves first loses its pawn. White plays h4, a spare tempo that also locks the h-pawns, so Black must move the king and the c5 pawn falls. Position (FEN): `8/8/8/2pK3p/1kP5/8/7P/8 w - - 0 1` A neighboring idea is [Tempo](https://georgelichess.com/glossary/tempo.md). A tempo is a single move counted as a measure of time: gaining one means making a useful move that also forces the opponent to react, while losing one means spending a move that accomplishes nothing. It sits close to [Trebuchet](https://georgelichess.com/glossary/trebuchet.md). The trebuchet is a mutual zugzwang in which two kings stand on either side of a pair of locked pawns, each beside the enemy pawn, so whoever must move loses a pawn and the game. A neighboring idea is [Triangulation](https://georgelichess.com/glossary/triangulation.md). Triangulation is a way for a king to hand the move to the opponent: it makes a three-move loop over neighboring squares and returns to its starting square, while the enemy king, with less room, cannot copy the loop.
