3. Nf6 Qh7 4. Qxh7 would have worked also.

Super problem,keep them coming !

Beautiful and thoughtful problem.  Knight promotion for the win!  Sometimes the underpromotion is the only answer, such as the case of unintentional stalemates.

Got it, but finding the fastest win is difficult in such a winning position with many different options and many different ways to go.

non queen promotions scare me

Stylish and superb.

LORYGRA

funny and tricky!

Interesting that the rook was employed to clinch the mate, I would have been inclined to use K(h)f6.

nf6 would work as well wouldn't it? For the third move if you move the h knight the queen would put him in checkmate.

Nic puzzle, although I do not know why it took me about 5 minutes to find out that you need to capture the rook for a pawn promotion.

easy

idraz

you can do the checkmate with other queen
