How?

1 24 Rxf6 Nxf6 25 Qxf6 doesn't win because Black's Queen is defend-ing g7. ² 24...Kg8 loses to 25 Bxf6+ Kf8 26 Qg7, mate.

1 Other moves drop the Re8. ² 17...Re6 loses to 18 d5, but better is 17...Qd8, e.g., 18 Kh2 Qe7 19 Rg1 Qg7, although Black is down two pawns after 20 Nxf6 Qxg6 (20...Nxf6 21 Qxg7 is mate) 21 Rxg6. ³ Hint: White can create a winning Knight fork in this position.
