Is it possible to create a position on a chess board with white to move where the only legal move checkmates black? it's probably quite simple but definitely an interesting idea sort of like a winning zugzwang

This fits the criteria.

By Ropke. White to play and mate in 6 moves.



Don't be put off by the six moves.
Teach anyone how to play chess and they will solve it right away.

All it requires is that both sides play their only legal moves.
The problem actually solves itself.

There are many legal moves in that position. 27 actually.

Do explain. AFAICT, two pawns can take the queen, and no other white piece can move. And yes, it's white's move, according to the FEN.

I think he said mate on the move, so one move to mate but only one legal move.

This fits the bill I think:



b7 # Simple, no?
