There's a mate in one if you think outside the box and its a legal chess move

only if you know blacks previous move was e5, but yes, that would do it.

No fair!  If I had seen the prior move of e5, then yes dxe6 e.p. ++ by discovered check and mate by the bishop on g2 will do the trick!!

Kxh6, the knight loses its protection from the queen

Since the puzzle is given as a mate in one, there must be a solution somewhere. While en passant is conditional in the given position (Black could have played d7-d5 or could have played other moves instead), en passant seems to be the only possibility to land an immediate mate. It follows correspondingly that Black must have moved d7-d5 prior to that, but I know that it is a bit not fair in this way.

The phrase 'it's a legal chess move' makes things a bit too obvious.

Then the king can take the knight, genius.

It looks like some people write comments here without taking time to actually THINK!

• #19
This isn't a legal position!

Quite ironic how you missed that a refutation to Qf6 has been published earlier in the same page in posts #10 and 11.
