How are checkmate sequences typically presented in notation in puzzle books?
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
As a numbered list of forcing moves, starting from a diagram of the position and running to the mating move, with the defender's replies included at each step rather than left implied. A typical entry reads something like: starting position diagram, then "1. C5+4 A5+6 2. C5=4 mate", showing both sides' moves through to the finish.
Why the defender's replies are spelled out
A mating sequence is only forced if every one of the defender's legal replies has been checked, not just the one the author had in mind. Puzzle books typically show the defender's best (or only) response at each step precisely to demonstrate that the sequence works against anything the defender might try, not just a single passive line.
Where the diagram fits in
Because a xiangqi board can be hard to hold in mind purely from notation, the starting diagram anchors the reader before the move list begins, echoing the broader habit discussed in why books still rely on diagrams alongside notation.
Related questions
Does the mating move get a special symbol?
No universal one, though many publications simply write "mate" or the Chinese 勝 after the final move rather than relying on a symbol.
Are alternative defences shown as separate branches?
Often yes, in parentheses, when more than one defensive try needs to be refuted to prove the sequence is genuinely forced.
