24.Bd5+ Rxd5 25.Re7, allows the counter-combination on the theme of closing lines: 25...Ne2+! 26.Kf1 (26.R7xe2 Rd1; 26.R1xe2 Rd1+ 27.Kg2 Bc6+ 28.f3 Bxf3+) 26...Rf7 27.Rxf7 Kxf7 28.Qxh7+ Kf8, with a draw by perpetual check.
A longer winning line was 25.Rxf7 Ne2+ 26.Rxe2 Rd1+ 27.Bf1 Rxf1+ 28.Kxf1 Qd1+ 29.Re1 Bb5+ 30.Kg2 Qd5+ 31.Kg1 Qxf7 32.Qf4, penetrating with the queen into Black’s camp.
Two rooks on the seventh rank are a fearful strength. Instead of the tempting bishop retreat to e2, White finds a way to pose threats against the enemy king.
Now, the white rook gets the f6-square, and Black loses another pawn on the kingside.
More tenacious was 26...Bh8!, although after a line such as 27.Kxe2 a5 28.Rfe7 Re8 29.Rxe8+ Rxe8 30.Ra7 Bg7 31.Rxa5 Bf8 32.Ra7 Be7 33.Kf3 h5 34.Bb6!, with the idea of transferring the bishop via c7 to d6, White retains good winning chances.

Black has not managed to evacuate his king (the queenside looks relatively the safest), and the game is now decided by energetic play along the central files:
