The line
- Red傌 h10–f9Checkmate.
Mate is immediate: no flight square, no capture and no block.
Why it is mate
A horse delivering mate beside the palace is the shape players call the trough horse, 卧槽马: it checks and covers escape points at the same time, and because a horse cannot be blocked by a piece in its path once it has landed, only capture or flight would help.
Read about this patternHow this puzzle was checked
Nothing here is an engine opinion. The position was solved by trying every legal defence to the full mate distance, so the claim that Red mates in 1 is a proof rather than an evaluation, and the first move shown is the only one that works. The defence in the line above is Black’s most stubborn try, not a convenient one.
