Show the solution
It starts with 傌 g8×h10. Look at what it does: it takes a defender off the board on the way, it removes 2 escape points from the General, and leaves Black 1 legal reply, none of which help.
The line
- Red傌 g8×h10Check. Black must answer.
- Black象 f6–h8Black's most stubborn defence.
- Red俥 i8×h8Checkmate.
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 chariot arrives on a line the defence cannot close. Chariots are the strongest pieces on the board and most finished attacks end with one, which is why a defender will trade almost anything to swap them off first.
Read about this patternHow 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.
