1. e2e4  1... c7c5  2. g1f3  2... b8c6  3. f1b5  3... g8f6 Caruana used this move faithfully during the Candidates Tournament. 4. b5c6  4... d7c6  5. d2d3  5... d8c7  6. h2h3 A typical move, preventing …Bg4. It's not really necessary and it's probably not the most accurate, despite being the most played. 6... e7e5  7. b1c3 [%c_effect c3;square;c3;type;Inaccuracy;persistent;true] This doesn't seem like a very good square for the knight, which should probably be heading to c4. 7... f8e7  8. c1e3  8... f6d7 [%c_effect d7;square;d7;type;GreatFind;persistent;true] The well-known maneuver …Nd7-f8-e6 (or g6) comes into play. It's important that Black is able to avoid the f2-f4 advance, which is the best plan for White. 9. f3d2  9... d7f8  10. e1g1  10... f8g6 [%emt 0:00:02][%timestamp 20] 11. c3e2 [%c_effect e2;square;e2;type;Inaccuracy;persistent;true] White doesn't have time to advance the f-pawn and it's better to forget this plan altogether. 11... g6f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true] Black arrives in time to pretend f2-f4. Something went wrong in White's opening play, as he is now left without a pawn break on both d4 and f4. Black, meanwhile, can reinforce his position, preparing to castle on the queenside and advance the pawns on the kingside. 12. a2a4  12... c8e6
