1. d4 d5 2. c4 e6 3. Nc3 Be7 4. cxd5 exd5 5. Nf3 c6 6. h3 $5 {This is far from
the most common continuation, but Morozevich has always been one to follow his
own lead, and not that of others. The main purpose here is to avoid any theory,
and just get down to playing chess.} Nf6 7. Qc2 g6 8. Bh6 Bf5 9. Qc1 Nbd7 10.

17. b4 a6 18. Nb3 f5 19. Nc5 Nxc5 20. bxc5 Ne4 21. gxf5 gxf5 22. h4 $1 {A
typical device to deny the h4 square for Black's bishop.} Rg8 23. Na4 Bd8 24.
Nb6 $1 Bxb6 25. cxb6 {The pawn structure has changed character, and the
constant threat of a Bxa6 and quick pawn promotion will define the enitre
endgame from here on. There is nothing inevitable about this but it taints
Roiz's play.} Ke7 26. Bf4 {With the bishop on f4, controlling b8, the
potential sac Bxa6 bxa6 and b7 is a constant concern.} Rae8 27. b4 {Morozevich
doesn't want to allow Black ...c5.} Bc8 28. Rc1 Bd7 29. Bd3 Kf7 30. f3 Nf6 31.
Kf2 Ra8 $2 {Black wants to free himself with ...a5, and prevent Bxa6 all at
the same time, however he miscalculates.} 32. Rhg1 Rxg1 33. Rxg1 {The problem
is that Black cannot challenge White for the g-file.} Be6 ({If} 33... Rg8 $2
34. Bxa6 {wins a pawn plain and simple.}) (33... a5 {also drops a pawn after}
34. Ra1 a4 35. Ra3 {and the a-pawn is a sitting duck.}) 34. Be5 h6 35. Ke2 Bd7
36. Kd2 Be6 37. Kc2 ({White misses a tactic, though forgivably, as he was
focused on schematic thinking here.} 37. h5 $1 {threatening Rg6, was tough to
meet.} Nxh5 38. Rh1 Kg6 39. e4 $1 dxe4 40. fxe4 Rf8 41. exf5+ Bxf5 42. Rg1+ Kh7

threats, the position is now won for White.} Nf8 46. Bc2 Ke6 47. e4 fxe4 48.
fxe4 Be8 (48... dxe4 $2 {is unplayable and loses.} 49. Bxe4 {and the threat of
b5! or Bf3 winning the pawn is unstoppable.} Be8 50. b5 Kd7 51. Bc7 Kc8 52.
