1. Qb8#

It's a selfmate. White must force black to checkmate white

Are you sure you have the position correct?

I put it in Problemiste and it says there's no solution.

Maybe because it is supposed to be black to move? Actually, that doesn't look possible either -.-

Selfmate  starts with white move

I think the solution may be 1. Nb6 threatening 2. Nxg7+ Qxg7 3. Kf5+ Qxe5#

1...Bg3 2. Qb8+ Bxb8 3. Bxf7+ Qxf7#
1...Bb1 2. Kd5+ Kd8  3. Kc4+ Nd6#

The Bb1 variation is quite astonishing.

Why not Bd6, and Ng5#?
