1. b2b3 Zherebukh needs to win on demand, and he summons all his creativity right from the start. 1... d7d5  2. c1b2  2... c8g4  3. f2f3  3... g4h5  4. h2h4  4... f7f5 After this, we are out of book as early as on move four! One could hardly  believed that this can still happen at the prestigious World Cup! 5. g1h3 A nice maneuver. The knight is heading towards the e5-square like  in the Stonewall. 5... g8f6  6. h3f4  6... d8d6 Eyeballing the white king! 7. e2e3  7... h5f7  8. d2d4 Fixing the e5- and c5-squares. 8... b8d7 But Shirov certainly  won't give those outposts without a fight. 9. b1c3  9... a7a6  10. c3e2 White  increases the control over the central squares and gets ready to bother  the enemy f5-pawn. 10... g7g6  11. f4d3  11... f8h6 As aggressive as possible! 12. d1d2  12... c7c5  13. d4c5  13... d7c5  14. d3e5  14... c5d7  15. e5f7 Zherebukh needs to unbalance, and a bishop pair  could be a great asset for the future. Plus, the black king is getting  exposed... 15... e8f7  16. e1c1  16... e7e5 This obvious move is not the most accurate,  though. 17. c1b1  17... d6c5  18. f3f4 Very risky play, but that is the only way to get to  the enemy king. 18... h8e8  19. h4h5 Very nice, the light squares are vulnerable. 19... h6g7  20. e2c3 A pity! 20... e5f4  21. h5g6  21... h7g6  22. e3f4  22... a8d8 Now Shirov has stabilized, but  it ain't over yet. 23. g2g4 It is not late for this chance. 23... f6g4 This is not bad. 24. b3b4 The exclamation is for bravery. Zherebukh needs to win,  remember? And he is desperately trying to remove the queen from the  d5-pawn. 24... c5c6  25. b4b5 Consistent! 25... c6e6 And Shirov cracks under the pressure. 26. c3d5  26... g7b2  27. d5c7 This nasty in-between blow was probably missed  by Black! 27... e6e3 This loses quickly. 28. f1c4  28... f7g7  29. c7e8  29... e3e8  30. b1b2 Zherebukh has won material and kept his attacking formation intact. He quickly forces the win: 30... g4e3  31. d2d4  31... d7e5  32. d4d8  32... e3d1  33. h1d1  33... e5c4  34. b2c3  34... e8d8  35. d1d8  35... a6b5
