[continued from the previous post]
Both sides have been shuffling their pieces around, perhaps searching for a plan.
18.Qg3 Nh8
A sturdier defensive move would be, 18...Kh8, unpinning the g-pawn, but the text seems fine, at first.
19.f5 Bd7
It was time to return some of the sacrificed material, for example, and even exchange Queens: 19...Rae8 20.fxe6 Ng6 21.Rf1 Nxe4 22.Qg4 Nxc3 23.Bxc3 d5 24.Rxf8+ Rxf8 25.Qd4 Qb6 when White would only have an edge.
The text allows White a strong shot.
20.Nd5
Hitting Black's vulnerable Knight at f6 again.
20...Kf7
Not 20...Nxd5 21.Qxg7 checkmate
21.Qh4
Overwhelming the defense.
21...Nxd5
Stockfish's idea 21...Qxd5 shows how dire the defender's position is.
22.exd5 Qxc2
Oh, well.
23.Re7+ Kg8 24.Rxg7 checkmate
