After 15.e2-e4

White's last move stops ...f5. White will continue with f4. 15...Rf8. This move was first proposed by Dutch GM Jan Timman. It prepares to take advantage of the soon-to-be-open f-file. Kasparov considers that after 15...f5 16.exf5 Bxf5 17.g4 Bxg4 18.hxg4 Qh4 19.gxh5 Rf8 20.h6 Bh8 21.Ne4 Ng4 22.Qxg4 Qxg4 23.Nxd6 Be5 24.Ne4, the three minor pieces are stronger than the Queen.

16.Kh2. Guards the Pawn on g3 and prepares f4. If 16.g4, then 16...Qh4 17.gxh5 Bxh3 18.h6 Bh8 19.Ne2 f5. 16...f5 17.f4. If 17.exf5 Bxf5 18.g4, then 18...Bxg4 19.hxg4 Qh4+.
