Again one of White’s knights is pretty far advanced up the board on f5; any knight planted on the fourth or fifth rank is a constant forking threat. So White does a quick scan for forks and observes that the knight is on a light square along with Black’s king and queen―which can be forked with Ne7+. The needed square is protected by one piece: the bishop on d6, but White can take out the bishop with his rook now on d1. So White picks up a piece, and if Black recaptures White can follow up with the fork: 1. RxB, c7xR; 2. Ne7+.
