context: 1. f2f4 An interesting situation that can happen in Chess960: White creates a decisive threat right from the first move. 1... f7f5 Black copies White's idea instead of wasting time defending the a7-pawn. 2. b2b4 This is a difficult move that requires a good understanding of the position. It was played in all the games of this round. 2... b7b5 Two alternatives were played in the other games. 3. g1a7  3... b8b7  4. a7d4  4... g8a2  5. b1b2  5... a2d5 Symmetry is maintained in a curious way. 6. e2e3  6... e7e6  7. e1d3 The wrong square. 7... d7d6 Finally a move that breaks the symmetry. 8. d3f2 This is wrong since now Black is in time to play c5, achieving an overwhelming advantage. 8... c7c5  9. d4c3  9... c5c4 With the a1-knight completely shut out from the game, White is positionally lost. This is also a characteristic of Chess960: some positions can get horrible quickly, even if you are playing White. 10. c3d4 Preparing c3 in order to give the poor knight a square. 10... a8b6  11. d4b6  11... b7b6  12. b2a2  12... f8e7  13. c2c3  13... e8f6  14. a1c2  14... e6e5  15. h1g1 A sad necessity. 15... d8h8 Everything is wrong with White's position. Caruana saving this is a case that miracles sometimes happen in chess. 16. g2g3  16... c8c6  17. c2e1  17... f8a8 Black takes the a-file and it looks like winning is a matter of time. 18. a2a8  18... c6a8  19. f1g2  19... b6a6  20. g2d5  20... f6d5
