Forcing the draw.
1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... a7a6  4. b5a4  4... g8f6  5. e1g1  5... f8c5  6. c2c3  6... b7b5  7. a4c2  7... d7d5  Quite a sharp line that, according to Caruana, was considered dubious  until recently, but the strong engines changed the assessment to playable  for Black. 8. a2a4  8... d5e4  9. a4b5  9... c8g4  10. b5c6  10... e4f3  11. g2f3  11... g4h3 This is the new trend. The position is super-sharp, and Black tries to prove that the opponent's  weakened king is worth the invested material. 12. f1e1  12... e8g8  13. a1a5  13... d8d6  14. b2b4  14... c5f2 This move made the big change. 15. g1f2  15... e5e4  16. f2g1  16... a8e8  17. e1e3  17... f6h5 \"It's a very dangerous line for Black. Black is basically making only moves not to lose.\" (Caruana) 18. f3f4 However, White also  needs to be very careful not to lose too! This move is a novelty, but  Caruana suspected that his opponent simply reverted the move order (see  below). 18... h5f4  19. a5g5  19... f7f5 \"This was easy to play and it was clear that  White is in great danger, maybe borderline losing.\" (Caruana) The white  rook is trapped, and without it his majesty suffers. 20. d2d4 However, this obvious move might have, in fact, been the real  mistake. 20... h3g4 Effectively trapping the rook. 21. g5g4  21... f5g4  22. d1g4 The critical moment of the game. 22... f4d3 And  Fabiano blunders an important defensive resource. 23. c2d3 The only move but a sufficient one. 23... e4d3  24. e3e8  24... f8e8  25. c1f4 A strong intermediate move missed  by Caruana. 25... d6c6  26. f4e5  26... c6h6 \"I am honestly kind of lucky that  I have this.\" (Caruana)
