10 minutes on the clock indicate that Vitiugov might have been choosing between this aggression...
1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... a7a6  4. b5a4  4... g8f6  5. e1g1  5... f8e7  6. f1e1  6... b7b5  7. a4b3  7... e8g8  8. d2d3 A modest move which, however, prevents the Marshall Attack. 8... d7d6  9. c2c3  9... c6a5 Yesterday's loss was certainly a painful blow for Vitiugov, who missed a shot to play for a place in the Candidates. Nevertheless, the Russian champion managed to put himself together and went fully mobilized in this final encounter. 10. b3c2  10... c7c5  11. b1d2  11... f8e8  12. h2h3  12... e7f8  13. d2f1  13... h7h6  14. d3d4 White opens the center, despite the delay of a tempo. 14... e5d4  15. c3d4  15... c5d4 The slightly compromised pawn structure will be compensated by the active black pieces. 16. f1g3  16... c8b7  17. f3d4  17... a5c4  18. b2b3  18... c4e5  19. c1b2  19... a8c8  20. d1d2  20... d8b6 Active play, and a novelty. 21. d4f5 Sjugirov wants to maneuver his knight to a better square, but this costs him quite a lot of time. 21... g7g6  22. f5e3  22... h6h5 An important move in the battle for the e4-square. 23. b2d4  23... b6d8  24. f2f3 This modest move is more or less forced. Sjugirov needs to overprotect his most important pawn.
