post in the comments what you think is the best move

The pawns are not about to promote

Threaten the queen with your knight

No
If knight d5,queen to e8 pins the knight and the rook can't protect the knight
If knight e6,queen d7 check, king e1,and queen b5 puts you in a sort of zugzwang: you either have to lose the knight or the rook

Oh

I said knight e6, but actually the move is rook to f6.

king g7 and king e7?
They are the easy ones

Cause king takes, royal fork

If king to g8?

If king to e8?

Rook to f6 is the correct move
