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

you can do the checkmate with other queen

nice

crazy!

interesting, but black was milti-screwed to begin with

I always prefer a queen once pawn reaches the last row. Knight was the better choice here.

gay

looks simple, but not so easy to forsee the 3rd move in real game

The topic headline made me think about something else... *cough* nvm...

nice

I quite liked that !

good one

The minor promotion was a nice find

No, queen is hitting that square. Do you have your glasses on?

funny

Nf6 would have have check-mated just as well as Rf8.

what about Nhf6 after Kh8. that should be mate

Rf8# is the correct solution because it's in only 3 moves but I prefer the Nhf6 move - it seems more elegant.
