1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. g2g3  3... d7d5  4. f1g2 A good opening choice. The dry Catalan can fight the immense creativity of the Polish GM. 4... f8e7  5. g1f3  5... e8g8  6. e1g1  6... d5c4  7. d1a4  7... c7c6  8. a4c4  8... b7b5  9. c4b3  9... c8b7  10. f1d1  10... b8d7  11. f3e5  11... d7e5  12. d4e5  12... f6d7  13. c1f4  13... d8c7  14. b1c3  14... d7c5 Duda does not want to follow the footsteps of other players. 15. b3c2  15... b5b4 A very committal move. Pawns are not moving back, and the  exposed b4 one will soon become a headache for Black. 16. c3b1  16... b7a6 In order to prevent the normal development after Nb1-d2, but  this is easily fixed by 17. g2f3  17... a8c8  18. a2a3  18... c8b8 Now the game opens in  White's favor. 19. a3b4  19... b8b4  20. f4e3 From here on Caruana will mercilessly improve his  queenside position until he wins material. 20... c7b7 Using small tactics Duda avoids the immediate collapse. 21. b1d2 The pawn is not as important as the pieces, and Caruana  quickly brings every piece he has on the queenside. 21... b4b2  22. c2c3  22... b2b5  23. a1a3  23... b7b8  24. d1a1  24... a6b7  25. a3a7  25... c5d7  26. d2c4  26... f8d8 Caruana managed to take his pawn  back and brought his pieces even closer to the enemy camp. But how to make progress on that part of the board? 27. f3e4 An excellent maneuver.  One idea is to attack the black king. Duda needs to try and free himself. 27... c6c5  28. c3c2  28... h7h6  29. e3d2  29... d7f8 A sad necessity. 30. e4d3 This is the second point behind Caruana's maneuver. The black  queenside is in big trouble now as the pieces obstruct each other. 30... d8d7  31. c4d6 Now White wins material. 31... b5b6  32. c2c5  32... b7d5  33. a7d7  33... f8d7  34. c5c8  34... d7f8  35. c8b8 Entering an endgame with excellent  winning chances. 35... b6b8  36. f2f4  36... e7d8  37. g1f2  37... f8d7  38. d2e3  38... g7g5  39. e3d4  39... b8b4  40. f2e3 Caruana is not only  centralizing his king, he is preparing a web for the black rook. 40... g5f4  41. g3f4  41... g8f8  42. d3b5 Finally going for the rook. 42... d7f6  43. e5f6  43... b4d4  44. a1c1 Well-calculated in advance. Caruana penetrates on the back rank and wins material. 44... d8f6  45. c1c7  45... f6h8 Drops a piece, but Duda's position is hopeless anyway. 46. c7c8  46... f8e7  47. c8h8
