1. e2e4  1... c7c6 "I did not expect the Caro-Kann at all." (Duda) 2. d2d4  2... d7d5  3. b1c3  3... d5e4  4. c3e4  4... g8f6  5. e4f6  5... e7f6 Twenty years back this line was considered dubious for Black as the assumption was White will be structurally way  better. The simplest plan is to trade everything and achieve a won pawn  endgame. Moreover, unlike the similar pawn construction as in the Ruy  Lopez Exchange, Black lacks the bishop pair to compensate for the ruined  pawn structure. However, recent GM practice has proved that Black has  serious arguments too, mainly the chance to play on both flanks. 6. c2c3  6... f8d6  7. f1d3  7... e8g8  8. d1c2  8... f8e8  9. g1e2  9... h7h5  10. c1e3  10... b8d7  11. e1c1  11... b7b5 "I totally forgot about this idea."  (Duda) "I knew such an idea exists, but did not bother analyzing it  seriously." 12. d4d5 "The first stupid thing I did was that I spent 20  minutes on calculating this move (and the recapture), and then Magnus  played c6-c5 at once." (Duda) 12... c6c5  13. d3b5  13... a8b8  14. c3c4  14... a7a6  15. b5a4  15... e8e7 Only this is a novelty. The rook is getting ready to  join the queenside assault. 16. e2g3  16... d7e5  17. g3e4 Now that the knight got centralized, White was happy. 17... e7b7 After this, Duda thought that Carlsen can "play whatever  he wants and will always have positional compensation." 18. b2b3  18... b7b4 A surprise for Duda. 19. e3d2  19... b4a4 Another nice positional exchange sacrifice. The white  king is exposed. 20. b3a4  20... c8f5  21. d1e1 "I thought I am in a very good  shape here. I was kind of very optimistic. " (Duda) 21... h5h4 And  indeed, now White is better. 22. h2h3  22... e5g6  23. e1e3 White has consolidated and even though the g2-pawn can be attacked, he can finally breathe freely. The game is approaching the  time-trouble phase. 23... g6f4  24. g2g4  24... f5g6  25. c1d1 "A very nice move." (Kramnik) "A clever way to  deal with the knight jumps." (Svidler) 25... f6f5 A natural attack, but  then the black king is getting weak too. 26. e4d6  26... d8d6  27. g4f5  27... g6h5  28. f2f3  28... d6f6  29. d2c3  29... f6g5  30. c2e4 "A very stupid move." (Duda) 30... g5g2  31. h1e1  31... g2a2 An obvious move, and a blunder. 32. e4c2  32... a2c4  33. e3e8  33... g8h7  34. e8b8  34... c4d5  35. c2d2  35... h5f3  36. d1c1  36... d5f5  37. e1e3 There are still many checks and threats against the white king,  but the two rooks are too much to handle. 37... f4e2  38. c1b2  38... e2c3  39. d2c3  39... f5f4  40. c3d3  40... f7f5  41. b8f8  41... f4b4  42. b2c1  42... f3e4  43. d3b3  43... b4d4  44. b3c3  44... d4d6  45. f8f7  45... d6g6  46. f7d7  46... g6g1  47. c1b2  47... c5c4  48. e3e4  No more threats.
