1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... g8f6  4. d2d3  4... f8c5  5. e1g1  5... e8g8  6. h2h3  6... d7d5 In the past, such aggression was deemed premature; however, the strong computers nowadays prove over and over that practically anything can be played. 7. e4d5  7... f6d5  8. b1d2  8... c8e6  9. d2e4  9... c5b6 Tabatabaei chooses to stay on the more active diagonal while still blitzing. Giri's next move, though, made him revise his beliefs about the situation. 10. b2b4 Quite a novelty $1 Giri is coming armed to the teeth for the game. White attacks the opponent's center from the flank, while opening the long diagonal for the bishop. 10... d5b4  11. c4e6  11... f7e6  12. a1b1 As a result of his fruitful preparation, Giri managed to spoil the opponent's pawn structure, and besides the weakness of the e-pawns, he can also enjoy a powerful attacking outpost on the e4-square. 12... h7h6 Tabatabaei decided to part with the extra pawn at once. 13. f3e5  13... c6e5  14. b1b4  14... a7a5 This looks suspicious. Why voluntarily weaken the queenside $2 15. b4b1  15... d8h4 Black does not have enough power to create trouble on the kingside, and after some preparation, Giri starts to show who is in charge. 16. d1e2  16... a8d8  17. g1h2  17... h4e7  18. f2f4  18... e5d7  19. f1f3 The white pieces constantly find beautiful working places. 19... d7f6  20. c1d2  20... e7a3  21. e4c3  21... d8e8  22. e2e5 A very neat queen maneuver $1 22... f6d7  23. e5b5  23... a3e7  24. b5c4 The queen is perfect on the c4-square. Once the black queen has been removed from the active position, White can start working on the enemy's weaknesses. 24... g8h8  25. c3e4  25... c7c6 And, as strange as it sounds, this is a decisive weakening. It is, however, difficult to find a way to avoid this move. 26. d3d4 Tabatabaei might have missed this. The kingside rook immediately rushes toward the now weak b7-pawn. 26... e8b8  27. f3b3  27... e7d8  28. c4e6  28... b6d4  29. b3b7 Plain and simple, White nets a pawn. 29... b8b7  30. b1b7  30... d7c5  31. e4c5  31... d4c5  32. b7d7  32... d8f6  33. e6f6  33... f8f6  34. d2c3 This was a bit rushy though. 34... f6f4  35. c3g7  35... h8g8  36. g7h6  36... f4a4  37. g2g4 The quality of the pawns is by far more important than their quantity. 37... a4a2  38. g4g5  38... a2c2  39. h2g3 The white pawns are moving fast while threatening mate and, therefore, Black's position remains gloomy. 39... c5e3  40. d7d8  40... g8h7  41. g3g4  41... c2d2  42. d8e8  42... e3c5
