1. d2d4  1... g8f6  2. g1f3  2... d7d5  3. c2c3  3... c7c6  4. c1f4  4... f6h5 A provocative and rare move. 5. f4g5  5... h7h6  6. g5h4  6... c8f5 A new move. Caruana had the chance to play g5 a few times, a natural move, but he probably wanted to avoid weaknesses as he just needed a draw. 7. e2e3  7... b8d7  8. f1e2  8... h5f6 A solid move instead of the aforementioned g7-g5. 9. c3c4  9... e7e6  10. b1c3  10... f8d6  11. c4c5 [%c_effect c5;square;c5;type;Interesting;persistent;true] Changing the character of the match. White now wants to advance on the queenside. 11... d6e7 It's hard to say if the bishop is better on e7 or c7. 12. f3d2  12... e8g8  13. h4g3  13... b7b6  14. b2b4  14... a7a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] This is a very good plan, exchanging queenside pawns to reduce weaknesses. 15. a2a3  15... a5b4  16. a3b4  16... b6c5  17. b4c5  17... e6e5 [%c_effect e5;square;e5;type;GreatFind;persistent;true] 18. d2f3 The most dangerous move in a rapid game, as Black needs to find a tactical solution. 18... e5e4 [%c_effect e4;square;e4;type;Mistake;persistent;true] Of course, Caruana knows the risks of opening the g3-bishop, but he probably didn't see an alternative. 19. f3d2 Now Artemiev has a clear advantage, as his pieces can invade the queenside and the c6-pawn is a big weakness.
