Show the solution
It starts with 傌 a8–b10. Look at what it does: it removes 1 escape point from the General, and leaves Black 1 legal reply, none of which help.
The line
- Red傌 a8–b10Quiet, and there is no answer to the threat.
- Black卒 c8–c7Black's most stubborn defence.
- Red傌 d6–c8Checkmate.
Every one of Black's 1 answers was played out to the end. The line below follows the most stubborn of them, the one that lasts longest and costs Red the most.
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 2 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.
