What is a waiting move in xiangqi and when should I play one?
These answers restate the rules implemented by our open-source engine, which follows the WXF laws and is regression-tested against the official 110-diagram repetition casebook. Where an answer refers to a specific position, that position lives on the linked reference page, where the build verifies it against the engine before publishing.
Direct answer
A move that improves your position without committing to a specific plan. A waiting move brings a piece to a more useful square, or removes a small weakness, while leaving your options open for the opponent's reply. 仙人指路 is the clearest example: it develops nothing but frees a horse, and Red can choose a plan once Black shows a hand.
When it is the right choice
Against an opponent whose system you do not know well, or in a symmetrical position where committing first can hand over the initiative, a waiting move lets you react rather than guess. It is a deliberate trade of speed for information. See what 仙人指路 does for the clearest example of this idea.
When it is the wrong choice
Once a real threat exists on the board, a waiting move that ignores it is simply a mistake, not a strategy. Waiting only works before there is anything to answer; after that, every move should be doing something concrete.

As a first move it usually is, since it develops nothing yet but keeps every plan open.
Can advisors or elephants make good waiting moves?
Rarely a good idea early, since they cannot cross the river and only change which palace points are covered.
