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

Red moves first. Find the move that forces mate whatever Black replies, then open the solution below.
Show the solution
The move is 炮 b5–d5. Look at what it does: it removes 1 escape point from the General.
The line
- Red炮 b5–d5Checkmate.
There is nothing to try. The General cannot move, the checking piece cannot be taken, and nothing can be interposed.
Why it is mate
The mating piece arrives on a square the defence cannot cover.
How 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.
