1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. b1c3  3... g8f6  4. f1b5  4... f8d6 A fighting move. Caruana avoids the many theoritecial drawish lines. 5. d2d3  5... e8g8  6. e1g1  6... h7h6  7. g1h1 Preparing a quick f2-f4 in the spirit of the Rossolimo line. 7... f8e8 Black wants to retreat the bishop to f8 once that his center  is defended. 8. b5c6  8... b7c6 Another fighting move. 9. f3g1  9... d6f8  10. f2f4  10... e5f4  11. c1f4  11... d7d5 This is why Caruana recaptured with the c-pawn. He wants a piece of the center. At this stage of the game the  American GM skillfully outplays his opponent. 12. e4e5  12... c8g4  13. d1d2  13... f6h5  14. a1e1  14... a8b8 Sending the rook to the center! 15. h2h3  15... h5f4  16. d2f4  16... g4h5 In order to keep the bishop more active. 17. c3d1  17... b8b4  18. f4f2  18... c6c5  19. b2b3  19... b4b6  20. g1f3  20... b6e6  21. d1e3  21... d8d7 So far  Black did everything fine, but this last move is a mistake. For a moment  Caruana stalls and this gives McShane the needed time to create his own  play. 22. g2g4 McShane seizes his chance. 22... h5g6  23. e3g2  23... c5c4  24. g2f4  24... c4d3  25. c2d3 Another accurate move. 25... f8b4  26. e1d1  26... e6e7 The counterplay is not good enough here. 27. f2a7 Snatching two pawns in a flash. 27... g6h7  28. a7d4  28... c7c5  29. d4d5  29... d7a7 The only chance is active play. 30. d5c4 Very accurate play again. 30... a7a2  31. g4g5 The knights are perfect for a close fight and the  kingside attack is the most natural way. 31... h6g5  32. f3g5  32... a2a8  33. h1g1  33... a8c6 Not the optimal square for the queen. 34. d3d4 Now that the central pawns come into motion Black's position is close to collapse. 34... h7f5  35. f4d5  35... e7d7  36. d5e3 Solid human move. 36... f5g6  37. d4d5  37... c6c7  38. e3g4  38... c7d8  39. e5e6 Very impractical. McShane was  left with his last seconds and there was no need to force matters. The  time control was approaching. 39... f7e6 Caruana misses his chance in return! 40. g5e6  40... d8b8 Sneekily looking at the enemy king from afar. 41. d5d6  Now McShane gets a second chance to finish the game. 41... d7d6  42. e6c7  42... d6e6  43. d1d7  43... g8h8  44. c4f4 The time to pick up the exchange came. 44... b8b6  45. c7e6
