Rxg3 f5 { Black has responded well to White's innovation. Now that h2-h3 had been played, it looks like White didn't get much besides the g-file, while Black has compensation in the form of a strong center. } 23. Rdg1 Rf7 24. Bg5 e4 25. fxe4 Ne5 26.

Rd1 f3 $15 { Both players are now under 20 minutes for the game. Black's f-pawn will cause some serious problems, but only as long as the knight stays on e5, meaning that White should be able to play around it. } 30. Qd2 Rfc7 31. c3 Rc4 32. Nd4 { A testing move. White's knight is now arguably better than Black's (with a black rook on c4 in its way, at least), and the f3-pawn is finally vulnerable, too. } 32... Ra4?! { Both players are under four minutes, and Robson drifts first. The intention of ... Ne5-c4 is clear, but this is too slow. } (32... Qb4! { was necessary to keep the balance.
