Red moves and mates in 2
Mate in 2, proven against every defence.
Red is to move and forces mate in 2. Black is not helpless: there are nothing but the General still on the board, and every legal defence has been tried against this solution. All of them lose.
The position
Red attacks with a soldier, a cannon and a chariot, and Black's General stands on e9. Black's defenders: nothing but the General.

Show the solution
俥 g7–g9 is the only move that wins. Look at what it does: it removes 1 escape point from the General, and leaves Black 2 legal replies, none of which help.
The line
- Red俥 g7–g9Check. Black must answer.
- Black將 e9–e8Black's most stubborn defence.
- Red俥 g9–f9Checkmate.
Black has 2 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.
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.
