Dude, that isn't a win, white can still move his king
"Victim" Knight error Check

Gwydion, White's King has to move into the corner, so the Knight will take the Queen with check. White will capture the Knight, so Black's Queen can take the White Bishop, leaving Black a Queen up.

11. Kh1 Nxg3+ and black takes the queen with check. On the next move black can play 12. ...Qxe6
Beat me to it :)

11. Kh1 Nxg3+ 12. hxg3 Qxe6 Black does not lose the queen. He gains a tempo when taking the white queen by also putting black in check. This saves his own queen.
I love this win more than most because of the opponent mal-practice of not checking the Knight.
