30...g5! [A typical move. Black fixes White's doubled pawns and secures the f4 square for his knight.]
31.Kg2 Nf4+ 32.Kg3 Rb1 [β³Rh1]
33.Kh2 [33.Rxf4? gxf4+ 34.Kxf4 Rh1 35.Bd3 Rxh3 36.Ke4 h5 37.Kf4 Rh4+ 38.Ke3 Rh1β+ β³h4]
33...Kg7 34.h4 Rd1! [Leko shows his excellent technique for converting the advantage. White's rook is now tied up to the g2βpawn and doesn't have any future prospects.]
35.hxg5 hxg5 36.Bb5 Kg6 37.Ba6 Kh5 38.Bb5 Kh4 39.Ba6 Rd2 40.Kg1 Kh5 41.Bc4 Kg6 42.Ba6 Kg7 [Black does not find a path to penetrate into the white kingside and decides to transfer his king to the other side.]
43.Bb5 Kf8 44.Ba6 Ke7 45.Bb5 Kd8 46.Re1 [Finally, White gives up the d4βpawn and tries to activate his rook. Other continuations don't help:]

37.Qh1! [This beautiful maneuver threatens to win the black queen and, moreover, brings his own queen to defend the d3βpawn.]
