1. d2d4  1... d7d5  2. g1f3  2... e7e6  3. c2c4  3... d5c4  4. e2e3  4... g8f6  5. f1c4  5... c7c5 The solid QGA. 6. e1g1  6... a7a6  7. b1d2 Andreikin, known for his original thinking, found an unbeaten path to fight against one of the most reliable black openings. 7... c5d4  8. f3d4  8... f8c5  9. d4b3  9... c5e7  10. c4e2  10... b7b5  11. a2a4  11... b5a4  12. a1a4  12... e8g8  13. d2c4  13... c8d7 Once Bacrot catches up with his development, he should have nothing to complain about. 14. a4a1  14... b8c6  15. b3d2 The game has been equalized and Andreikin needs to find something interesting if he wishes to win the group outright. 15... f6d5  16. d2f3 The point behind the maneuver: the knight reaches the almost-perfect e5-square. The ideal one would be the c6 square, but how to get there $2 16... c6b4 Bacrot also improves his situation on the queenside. 17. c1d2  17... d8b8  18. c4e5  18... d7b5 Once the problem of this bishop is solved, it seems as if the game would soon peter out in a draw. 19. e2b5  19... b8b5  20. f3d4  20... b5b7  21. d1b3  21... b7c7  22. d4f3 Black's only minor problem could be the c-file and, in particular, the c6 square. 22... f8b8 A natural move. 23. f1c1  23... c7d6  24. e3e4 That is the chance that White was searching for $1 Now things get spicy. 24... b4c6 Black accepts the challenge $1 25. b3b8 And even spicier $1 Andreikin spent a bit over a minute on this move, and it is strictly his only way to play for something. Moreover, it was evident that he was heading for this sacrifice in advance, and his intuition did not fail him. 25... c6b8 An only move. 26. c1c8  26... e7f8 And an only move again. 27. e4d5  27... e6d5 Bacrot spent valuable ten minutes from his remaining time for the capture, but did not guess right. 28. a1c1 But this time Andreikin did not guess right $1 28... f7f6  29. e5c6 And this, too, only plays into Black's hands. 29... a6a5  30. c8d8 All very natural, very scary, and well off the mark $1 30... d6c7  31. f3d4  31... c7b7 Bacrot gets very close to complete consolidation but also-very short of time. Now the real drama starts. 32. c6a5  32... b7b2  33. d4b3 The danger in the game influenced Andreikin. 33... g8f7 The king is on the run. Once it is out, the black extra material should finally prevail. 34. d2f4  34... f8b4  35. c1c7  35... f7g6  36. d8g8  36... b4a5  37. b3a5 The culmination of this incredible thriller. Bacrot played the most obvious 37... a8a5  38. g2g4 A nasty move in the time trouble. The black king is in a mating net. Black spent his last seconds for 38... b8d7  39. c7d7 When short of time, the human gives checks. So did Bacrot 39... b2b1  40. g1g2  40... b1e4  41. g2g3
