Find the mate in 1
Mate in 1, proven against every defence.
A one move finish, Red to play. Black holds a soldier and a cannon, which is enough to survive most attacks and not this one.
The position
Red attacks with 2 horses and a soldier, and Black's General stands on d10. Black's defenders: a soldier and a cannon.

The line
- Red傌 b10–c8Checkmate.
There is nothing to try. The General cannot move, the checking piece cannot be taken, and nothing can be interposed.
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.

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.
