21...Qe7 Fritz suggest sacrificing the queen for a rook and knight with 21...b5 22. Qc3 Qxd1+ 23.Rxd1 Be6 24.Qxc6 though white still have better game i believe 22.Nxg7 Kxg7 23.Nh5+ Kh8 24.Bc5 Qe6 24...Qc7 doesn't help because 25.Nxf6 Threatening 26.Qh4! for e.g 25...Re5 26.Qh4 h5 27.Rxg6 25.Rge1 Qxe1

25...Ne5 Also lost after 26.Qxe6 Bxe6 27.Nxf6 Bg4 28.Nxe8 Rxe8 (28...Bxd1 29.Rxe5) 29.f3 Bxf3 30.Rxe5 Rxe5 31.Rd8+ Kg7 32.Bd4 Kf6 33.Re8 26.Qxf7! Qxd1+ 27.Kxd1 Bg4+ 28.Kd2 Rad8+ Black can hold on a little bit longer with a stuborn defense after 28...Red8+ 29.Kc3 Rd7 30.Qxf6+ Kg8 31.Bd4 Bxh5 though white is still winning ( 31...Rad8 is checkmate in 4 after 32.Qh8+ Kf7 33.Qg7+ Ke6 34.Nf4+ Kf5 or 34...Kd6 bot will be answer with35.Qe5# checkmate) 32.Qh8+ Kf7 33.Qxa8 29.Kc3 Bxh5 30.Bd4 Rxd4 31.Qxe8+ 1–0
