How do you spot a mate in two in xiangqi?
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
Count the general's genuinely available points — usually two or three, not nine — then look for a move that covers the last of them while something else delivers check. Because the palace is small and the defender's own pieces block some of it, mates in two are far easier to see here than in chess once you count first.
The order that works
- List the general's escape points. Subtract those occupied by its own pieces and those your pieces already cover.
- Find the checking move that the defender cannot capture or block.
- Check the named patterns — 馬後炮, 重炮, 雙車錯 — because if the material matches one, the mate is probably that.
The commonest oversight
Forgetting your own general. In simplified positions it covers the file it stands on, which is frequently the escape point you were looking for a piece to cover.
Related questions
Do I need to calculate deeply?
Rarely. Counting escape points does most of the work; the calculation is short once the count is right.
How do I practise this?
Mate-in-two puzzles specifically, rather than general tactics. The skill is counting, and it trains quickly.
