1. Qxd5+

(The Queen moved from g2, capturing the Knight at d5 and giving check.) Black now has a choice of three moves in reply:

1. ... Kh4 to which White replies with 2. hxg6 mate!

1. ... Bxd5 to which White replies (now that Black's Knight is no longer guarding the square): 2. Be7 mate.

1. ... exd5 to which White's response is again 2. Be7 mate.
