1.Nf6+!gxf6
2.exf6Ng6
If 2... Qe6 3.Qxe6 fxe6 4.fxe7 Nxe7 5.Re1 Kf7 6.Rc7 followed by Nd4 or Ne5+ with a won game for White
3.Qd2!
3.Qb5 would regain the piece at once, but the text is more forcing, threatening Qxh6 followed by mate
3...Qf5
If 3... Kh7 4.Nd4 regains the piece with decisive advantage
4.Qxh6!Qxf6
5.Rxc6!Qxb2
If 5... Qxc6 6.Ng5 forces mate
6.Rd4!Qb1+
7.Kh2Qf5
8.Rg4
And White resigns, perhaps a little early, but for example, after 8... Rbc8 9.Rcxg6+! fxg6 10.Rh4 Rfd8 11.Qh8+ Kf7 12.Rh7+ Ke6 13.Nd4+ there's only one outcome
