11.f4 {?! A dubious move which restricts the scope of his
dark-square bishop.} O-O 12.Nf3 Bd7 13.Kh1 Qb6 14.Ne5 Be8
15.Ng3 Ne7 {To reinforce the f5 square against White's
projected f5. Black also prepares the exchange of
light-squared bishops.} 16.Be3 Bb5 17.f5 {The thematic
advance, but Black can safely win a pawn.} Bxd3 18.Qxd3 exf5
19.Nxf5 Nxf5 20.Rxf5 Qxb2 21.Raf1 {Threats on the f-file force
an advantageous simplification.} Rac8 22.R5f2 Qc3 23.Qxc3 Rxc3

not choose the most accurate path.} Nf2+ 30.Kg1 Nd3 31.Be3 a6
