Defence by Declining a Sacrifice
Black spots an opportunity to sacrifice his Knight (Ne6), on f4, and is about to play 1...Ne6xf4. White can see it would be a mistake to capture (2...g3xf4), because of the threat from Black's Queen (Qc7) and Knight (Nh5).
What move should White play, to decline Black's sacrifice attempt?
