Red moves and mates in 1
Mate in 1, proven against every defence.
Red is to move and forces mate in 1. Black is not helpless: there are 2 advisors still on the board, and every legal defence has been tried against this solution. All of them lose.
The position
Red attacks with 2 cannons and 2 horses, and Black's General stands on e10. Black's defenders: 2 advisors.

Mate is immediate: no flight square, no capture and no block.
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.
