Congrats to GM Ian Nepomniachtchi (2771) on winning the #DvoretskyMemorial with 7/9 points. #chessnews
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 [△Rh1]
33.Kh2 [33.Rxf4? gxf4+ 34.Kxf4 Rh1 35.Bd3 Rxh3 36.Ke4 h5 37.Kf4 Rh4+ 38.Ke3 Rh1–+ △h4]
33...Kg7 34.h4 Rd1! [Leko shows his excellent technique for converting the advantage. White's rook is now tied up to the g2–pawn and doesn't have any future prospects.]

43.Bb5 Kf8 44.Ba6 Ke7 45.Bb5 Kd8 46.Re1 [Finally, White gives up the d4–pawn and tries to activate his rook. Other continuations don't help:]
