Knight - Queen attack on castle (7 moves)

Here is a game I played as black last week-end with a Fisher set clock.

I was under time pressure when I gave away the pawn, weakening my attack and letting my opponent regain somekind of offensive game with his doubled rooks.

However, he didn't see that coming! checkm

Also, don' tworry about the time because passe the 40th move you get an extra hour =).

Guess I didn't see Ng2++ if  the king went in e1 :)

Thanks for the tip Thompson 

That was a 7 move puzzle? Wait up, I have a 10 moves puzzle coming right up without a possible fail this time and 3 different variations.

...all that against a 2200 player!

And there is another treat_puzzle early in the game.

7 moves puzzle ha?

..Nf3+! 2. Kg2 Nh5+ ( if White plays Kg1 white is mate Qg2#) 3. Kf1 Qd3+ ( if white plays 4.Kg2 Qd1+ 5.Rxd1 Rxd1#) 4. Qe1 Ng2#
