The line
- Red傌 f5–g7Check. Black must answer.
- Black將 e8–d8Black's most stubborn defence.
- Red炮 i5–d5Checkmate.
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
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.
