Kh1 Nf2+ 20. Kg2 Nxd1 21. Rxd1 Rcd8 22. e6 Nf6 { White's serious control of the center compensates for the Exchange and thensome. } 23. Rxd8 Rxd8? { An error, leaving the f7-square unguarded. White begins illustrating why with a series of moves that force Black's bishop to e7, where it interferes with the queen. } 24. e5 Ng4 25. Bxg4 hxg4 26. Ne4 { Now, the bishop has to go to e7. } 26...

Ng5! $18 { With the point that White's bishop can cover the f8-square, making White's f-pawn far faster than Black's a-pawn. A hard detail to appreciate. }) 33... Rb3 34. Bd4 Rxb4 35. Ke3 b5 36.
