Lovely

A little too easy....

right

yeah good puzzle.

Very easy.

Thought  you had something there for a moment  but after 11.Nxf6, capture the knight with the pawn & it opens the rank for the black queen to protect the h7 pawn !

11. Nxf6+ Rxf6 ( 11... Qxf6 12. Qxh7# ) ( 11... gxf6 12. Qxh7+ )
12. Qxh7+ Kf8 13. Qh8#

But you're right, capture the (white) knight with the queen or rook & it's mate in 2 or 3 moves     

easy

tough one 

very nice

Please be relevant, helpful & nice!

last page :)

If 11.Nxf6+ then black can reply with 11...gxf6 and now white cannot mate with Qh7 because black's queen is protection h7.

Note that this is why Thomas' 10th move was 10...Qd8e7. He foresaw your line. What he missed was that if you change the move order then the same idea now works!

I page

I now practice working out my moves, in my head, prior to moving a piece. This was a great exercise for the mind. I likes.

It took me too much time to see the obvious.

very easy

It is mate if you do 0-0-0 in the last move.
