1. e2e4  1... c7c6 Due to the match situation, I expected this pawn moving one square more forward. 2. d2d4  2... d7d5  3. b1d2  3... d5e4  4. d2e4  4... c8f5 The good old Caro-Kann main line. 5. e4g3  5... f5g6  6. h2h4  6... h7h6  7. g1f3  7... e7e6 The same move Carlsen chose in his first world championship match against Anand in 2013. 8. f3e5  8... g6h7  9. f1d3  9... h7d3  10. d1d3  10... b8d7  11. d3e2  11... g8f6  12. e1g1 As far as I know, this move has been tried just once before, in a correspondence game. Usually White doesn't castle short after playing h2-h4, but the current game shows this plan is also interesting. 12... f8e7  13. f1d1  13... e8g8  14. c2c4  14... d8a5 A new move. I'm not sure this is a good square for the queen. This is a critical moment: White must decide on a plan of action, and there are several promising continuations. 15. c1f4  15... a8d8  16. d1d3  16... d7e5 [%c_effect e5;square;e5;type;GreatFind;persistent;true] 17. d4e5  17... f6h7  18. g3e4 [%c_effect e4;square;e4;type;Interesting;persistent;true] This pawn sacrifice was played after long thought. I like this decision. 18... d8d3  19. e2d3  19... e7h4  20. e4d6 The d6-knight gives good compensation for the sacrificed pawn, but not enough for an advantage. 20... a5b6  21. d3e2  21... f8d8 [%c_effect d8;square;d8;type;Inaccuracy;persistent;true] This move leaves the bishop in a dangerous situation. 22. f4e3 [%c_effect e3;square;e3;type;GreatFind;persistent;true] 22... b6c7  23. e2h5 [%c_effect h5;square;h5;type;GreatFind;persistent;true] 23... h4g5  24. f2f4  24... g7g6 The only defense. 25. h5f3 It's hard to say where the queen should go. 25... g5e7  26. c4c5 White has improved her position and has the initiative. 26... b7b6 [%c_effect b6;square;b6;type;GreatFind;persistent;true] It's necessary to look for active play. 27. b2b4  27... b6c5  28. b4c5  28... d8b8  29. g2g4 [%c_effect g4;square;g4;type;Mistake;persistent;true] A careless move. It's better to develop the a1-rook before going for the f5-break. 29... c7a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] 30. a1f1  30... a5c3  31. d6e4 [%c_effect e4;square;e4;type;Inaccuracy;persistent;true] 31... c3d3  32. g1g2  32... b8b2  33. e3f2  33... d3d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] The situation has become critical for White. 34. f1d1  34... d5a2  35. f4f5  35... e6f5  36. g4f5  36... g6f5  37. f3f5  37... a2e6 [%c_effect e6;square;e6;type;Mistake;persistent;true] A solid decision to exchange queens during time trouble, but this lets the advantage slip away. 38. f5e6  38... f7e6  39. d1d7  39... e7h4  40. g2f1  40... h4f2  41. e4f2 Despite being two pawns down, White has excellent drawing chances. The rook is active, and the c6-pawn can be attacked. 41... a7a5  42. d7a7  42... b2b5  43. f2d3  43... h7g5  44. a7a6  44... g8f7  45. a6c6  45... b5b3  46. f1e2  46... a5a4  47. c6a6  47... a4a3  48. d3f4  48... b3c3  49. c5c6  49... f7e7  50. e2d2
