Show the solution
The move is 俥 g5–f5. Look at what it does: it removes 1 escape point from the General, and leaves Black 1 legal reply, none of which help.
The line
- Red俥 g5–f5Check. Black must answer.
- Black車 b6–f6Black's most stubborn defence.
- Red俥 f5×f6Checkmate.
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 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.

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.
