Abasov chooses the most critical line.
1. e2e4  1... c7c5  2. g1f3  2... e7e6 Abasov chooses this move order probably to avoid the fight in the Rossolimo Variation (2...Nc6 3.Bb5). 3. d2d4  3... c5d4  4. f3d4  4... b8c6  5. b1c3  5... g8f6  6. c1f4 [%c_effect f4;square;f4;type;Interesting;persistent;true] As I have written many times, I believe Caruana is the player with the best opening preparation in the world. He always comes with all sorts of ideas, be it a new plan, a forgotten move, or the 10th choice of the computer. Coupled with that, he has a fantastic memory and is able to replicate his analysis during the game. 6... f8b4  7. d4b5 [%c_effect b5;square;b5;type;GreatFind;persistent;true]
