What is a tempo in xiangqi and why does it matter?
These answers restate the rules implemented by our open-source engine, which follows the WXF laws for movement, checkmate and both repetition rulings: a side that forces a repetition by perpetual check or perpetual chase loses rather than drawing. The chase half has not been validated against the official casebook. Where an answer refers to a specific position, that position lives on the linked reference page, where the build verifies it before publishing.
Direct answer
A tempo is one move's worth of time. It matters more in xiangqi than in most games because attacks are concrete and the general cannot run — so in a position where both sides are attacking the same points, the side that gets there one move earlier simply wins.
Where it is most visible
順炮, where the position is completely symmetrical. Every tactic Red finds, Black has too, one move later. The player who copies moves without understanding loses to a tactic that arrives a tempo early — which is the whole lesson of that opening.
How tempi are lost
- Moving the same piece twice in the opening for no gain.
- Answering a threat with a move that does nothing else.
- Striking before the second attacker has arrived, giving the defender a free move.
