1 … Kf7 (Fig.)
★ Spoiler alert! See below for the answer. ★

The main line is supposed to be the better response. The underlined are the actual continuation in the game.
2. Qc7!
[2. Kf1?? Qb5+ 3. Nc4 (2. Kg1 Ne2+) Bxc4+ 4. Rxc4 Qxc4+ 5. Qd3 Qxd3+ 6. Rxd3 Nc6 0-1
[2. Rc7?? Ne2+ 3. Kh1 Nxg3+ 4. fxg3 Qxc7 {the knight check stops White from forking the Black queen}
[2. Qh4! {this continuation is okay} Rfc8! {avoiding 3. Rxd4} 3. Qh7+ Ke8 4. Qxd7+ Kxd7 5. Rxd4+
[2. Rd2? Nf3+ 3. Qxf3 Qxd2]
2. … Rac8
Black still tries to avoid 3. Rxd4
3. Qxd7+ Bxd7 4. Rxc8±
Stockfish suggests 4. … Nf3+ for the desperado knight. Anyway, the black knight cannot be kept. White has excellent g- and h-pass pawns, and is likely to win the endgame.
