With the threat of Qf6-b2+ above all.
1. e2e4  1... c7c5 Dominguez mainly uses the solid open games against strong opposition, but today he decided to play big and opted for his beloved Sicilian. 2. b1c3  2... d7d6  3. d2d4  3... c5d4  4. d1d4 Probably this line was the reason. Shirov had used it quite a bit lately, and Black had prepared well for it. 4... b8c6  5. d4d2  5... g7g6  6. b2b3  6... f8h6 Asking White the awkward question: do you trade the dark-squared bishops, which would be an opening failure, or do you self-pin $2 7. f2f4  7... g8f6  8. c1b2  8... e8g8  9. e1c1  9... e7e5 Black is practically blitzing and Shirov starts to take time on his clock. In fact, for the next three (still known moves) the Latvian-born-Spanish GM would spend more than an hour of his precious time. 10. g2g3  10... f8e8 An obvious and strong move. It is Dominguez who is better developed, thus he is the one seeking a quick opening of the center. 11. c1b1  11... c6d4  12. f1g2  12... c8g4  13. d1f1  13... d6d5 Of course $1 Black is hardly trying to take over the initiative. And notice: he does this while heavily on top on the clock. 14. h2h3 This logical move is a novelty. 14... g4e6 Black also starts to think a lot and this would soon lead to mutual time-trouble. 15. g3g4 Fire on board $1 15... f6e4  16. c3e4  16... d5e4  17. g2e4  17... a8c8 The center has been opened and both sides start their walk into the minefield. 18. d2d3 Unpinning seems best. 18... d8a5 A risky affair. 19. f4f5 The logical follow-up which, however, has a hidden flaw. 19... e6d5 The most logical move. 20. h1h2  20... d5e4  21. d3e4  21... d4b5 Again the most logical continuation. This knight is looking for glory $1 22. e4b7 Shirov decided to risk it and snack on the pawn. 22... b5d6 The point behind the maneuver. Dominguez wants to bring his passer into motion while opening the important long diagonal. 23. b7f3  23... e5e4  24. f3d1 Stepping on a mine... 24... d6b5 Back to the c3-spot $1 Once the diagonal has been opened, both sides want to have it, no matter the price. 25. c2c4  25... b5c3  26. b2c3  26... a5c3 Practically, it is over. The huge battery on the long diagonal leaves the white pieces horribly fragile. 27. h2c2  27... c3e5 Luring the white queen away from the first rank. 28. d1d5  28... e5f6 Now the rook on f1 is hanging. 29. a2a3  29... h6g7  30. b1a2  30... c8d8  31. d5a5  31... d8d3 The decisive infiltration begins. The Cuban-born-American GM will force more weaknesses first. 32. g1e2  32... e8b8  33. b3b4  33... b8d8 Both players are in horrible time trouble, but it is far easier to attack than to defend when low on time. 34. b4b5 Missing his last chance. 34... e4e3  35. f1c1
