The line
- Red俥 g10×e10Check. Black must answer.
- Black將 d10–d9Black's most stubborn defence.
- Red炮 f6–f9Checkmate.
Black has 1 legal moves after the first blow and each was refuted to mate. The main line shown is the toughest defence rather than a convenient one.
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 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.
