1. d2d4  1... g8f6  2. g1f3  2... d7d5  3. c1f4 An unexpected opening choice by Duda, at least for his opponent. 3... g7g6  4. e2e3  4... f8g7  5. f1e2  5... e8g8  6. b1d2  6... c7c5  7. c2c3  7... b7b6 \"I knew this line is playable. Black accepts a slightly worse position.\" (Caruana) 8. f3e5  8... f6d7  9. h2h4 A very straightforward and logical attempt, but Black was not too worried about it. 9... d7e5  10. f4e5  10... b8c6  11. e5g7  11... g8g7  12. h4h5  12... d8d6 \"After this I did not think I was any worse. He is only attacking with a pawn, the rest of his pieces are not attacking.\" (Caruana) 13. d1a4  13... c5d4  14. e3d4  14... c8f5  15. d2f1  15... g6g5 An important move that seals the kingside, in the spirit of the Sicilian Dragon. 16. f1e3  16... f5d7  17. h5h6 Otherwise Black will place his pawn on this square. 17... g7h8  18. a4b3  18... e7e6  19. a1d1 A couple of strange moves, according to Caruana and now the white king remains in the center till the rest of the game. 19... a8c8  20. b3c2 Duda does not yet execute his idea. 20... f7f5  21. c3c4  21... c6e7  22. c2c3  22... e7g6  23. b2b3  23... d6e7 A nice maneuver! Black is occupying both long diagonals with his bishop and queen and gets ready for the opening of the center. That would certainly be most painful for the white king. 24. g2g3  24... d7c6  25. h1h5  25... e7f6  26. d1d2  26... g6e7  27. e3c2  27... f5f4 It is time to open up some files against the white king. 28. g3f4  28... g5f4  29. e1d1  29... c6e8 The same policy of a gradual improvement before any forcing moves. Indeed, the white king is permanently weak, and there is no need to rush. 30. h5h3  30... e8g6  31. c2e1  31... g6f5  32. h3h1  32... d5c4  33. b3c4  33... b6b5  34. c4c5  34... e7d5 This also looks great and Duda is completely outplayed, but the time-trouble is about to take its toll. 35. c3b2  35... b5b4  36. e2d3  36... a7a5 Solid, obvious and wise in time-trouble. 37. d1c1 Duda exploits the slightest hesitation. 37... d5c3  38. e1f3  38... f8d8  39. b2c2  39... f5d3  40. d2d3  40... d8d5 The time-trouble is over, and it is evident that White made a lot of a progress. Duda's next move though turned out to be a mistake. 41. f3e5 \"I was kind of happy to see this.\" (Caruana) 41... c3b5 \"After this it was a very straightforward calculation.\" (Caruana) 42. h1d1 And this might be the last mistake. 42... b5d4 Now it worked even better than in the line above. 43. d3d4  43... c8c5  44. d4d5  44... c5c2  45. c1c2  45... e6d5  46. d1d5  46... h8g8 The king runs into safety and Black converts his material advantage. 47. d5a5  47... f6f5  48. c2b3  48... f5b1  49. b3c4  49... b1e4  50. c4b3
