1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. f1b5  3... b8d7 This is the most combative option against the solid check on b5, a move that Sicilian players generally don't like to see on the board. 4. d2d4  4... c5d4  5. d1d4  5... a7a6  6. b5e2  6... g8f6  7. e1g1  7... e7e6 Just like in his game against Svidler, Korobov is ready to choose the pawn formation with e6, even though it's not the most popular. 8. b1c3  8... d8c7  9. a2a4  9... b7b6 Korobov played all this before in a Titled Tuesday game. Nowadays, studying blitz games has become common practice when working on opening preparation. 10. c1g5  10... c8b7  11. f3d2 [%c_effect d2;square;d2;type;Interesting;persistent;true][%c_arrow d2c4;keyPressed;none;from;d2;opacity;0.8;to;c4;persistent;false][%c_highlight b6;keyPressed;none;opacity;0.8;square;b6;persistent;false,d6;keyPressed;none;opacity;0.8;square;d6;persistent;false] A dangerous plan: the knight is heading to c4, from where it will apply pressure on the pawns on b6 and d6. 11... h7h6 [%c_effect h6;square;h6;type;GreatFind;persistent;true] A novelty and a provocative move. 12. g5f6 [%c_effect f6;square;f6;type;GreatFind;persistent;true] The clearest attempt to refute Black's previous move. 12... d7f6  13. d2c4  13... c7c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] The only move to justify Black's play. He needs to play a series of forced moves to achieve equality. This is always a little scary unless prepared beforehand. 14. a1d1 There are two important options, but Black is always surviving. 14... c5d4  15. d1d4  15... d6d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] This is the whole point. 16. e4d5  16... f8c5  17. d4d1  17... e6d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] 18. e2f3 [%c_effect f3;square;f3;type;Inaccuracy;persistent;true] This is inaccurate since it allows Black to castle queenside. 18... e8c8  19. c4e5  19... h8e8 [%c_effect e8;square;e8;type;GreatFind;persistent;true] The knight is forced back: capturing on f7 leaves the poor piece trapped. 20. e5d3  20... c5d6 Black has other tempting moves. In general, his position is already more comfortable, although the advantage is not substantial yet. 21. c3e2 [%c_effect e2;square;e2;type;GreatFind;persistent;true] 21... f6e4  22. e2d4 With the knight well placed on d4, the position is equal again. 22... c8c7  23. h2h4  23... d6e7  24. g2g3  24... e4c5  25. d3c5 A difficult move to play; after all, it connects Black's pawns, and the structure changes from isolated pawns to hanging pawns. 25... b6c5  26. d4e2  26... g7g5 [%c_effect g5;square;g5;type;GreatFind;persistent;true] Restricting the knight and creating chances on the kingside. 27. h4g5  27... h6g5  28. d1d2  28... e7f6  29. f1d1  29... b7c6  30. b2b3  30... d8d7  31. g1f1  31... e8d8  32. d2d3  32... c5c4  33. d3d2  33... d7d6  34. e2d4 Again, the knight is well placed on d4, and the position is balanced. 34... c6d7  35. f3h5 [%c_effect h5;square;h5;type;Inaccuracy;persistent;true] This is not a good spot for the bishop, and taking the f7-pawn leaves the king unprotected, so this is basically a loss of time. 35... f6g7 [%c_effect g7;square;g7;type;Inaccuracy;persistent;true] 36. f1g1  36... f7f5  37. h5e2 The bishop finally returns home. 37... c7b6  38. a4a5  38... b6c5  39. c2c3 [%c_effect c3;square;c3;type;GreatFind;persistent;true] 39... g7d4  40. b3b4  40... c5c6  41. d2d4 [%c_highlight d5;keyPressed;none;opacity;0.8;square;d5;persistent;false] The flow of the position has changed: it looks like White is the one pressing now due to the better pawn structure, but in fact, it's just a draw. 41... d7e6  42. e2f1  42... e6f7  43. d1d2  43... f5f4 [%c_effect f4;square;f4;type;Interesting;persistent;true] Korobov is an active player, and he was probably still playing for a win at this point. 44. f1g2  44... c6b5  45. g2f3 [%c_arrow f3e2;keyPressed;none;from;f3;opacity;0.8;to;e2;persistent;false,f3d1;keyPressed;none;from;f3;opacity;0.8;to;d1;persistent;false] It's important that the bishop can go back to e2 or d1. 45... f4g3  46. f2g3  46... d8e8  47. f3d5  47... d6d5  48. d4d5  48... f7d5  49. d2d5  49... b5a4  50. g1f2  50... a4b3  51. b4b5  51... a6b5  52. d5b5  52... b3c3  53. a5a6 At this point, I stopped following the game live and went out for lunch. I was really surprised to learn later that White had won this position. The game is a draw in many ways. 53... e8a8  54. b5b6  54... c3d4  55. f2e2  55... d4c5  56. b6g6  56... c5b5 [%c_effect b5;square;b5;type;Inaccuracy;persistent;true] The first step in the wrong direction. 57. g6g5  57... b5a6 [%c_effect a6;square;a6;type;Blunder;persistent;true] A dramatic blunder. 58. g5c5 The c-pawn is captured, and the king is too far from the g-pawn. 58... a8e8  59. e2f3  59... e8f8
