As is often the case, calculation provides the answer. With the queen on d2 the move 9...d5 is much more attractive for Black. 9... c6b4  10. e1c1  10... a8c8  11. c1b1 [%c_effect b1;square;b1;type;GreatFind;persistent;true] Once again the principle \"if in doubt, play Kb1\" shows its value. 11... d8c7 We're approaching the critical moment of the game and here I would like to address a typical myth that exists about the games of elite grandmasters, that is, that they know everything in the opening. Judging by the time spent and also by Vidit's comments after the game, both players were already out of preparation, even though the position was tactical, with natural moves that are also suggested by the computer and several games by strong grandmasters. This demonstrates once again, for those who still doubt it, that what wins games even at this level is skill on the board and not memory. 12. a2a3 This move invites big complications, as Black is forced to sacrifice the knight. 12... b4c2 [%c_effect c2;square;c2;type;GreatFind;persistent;true] The only way to justify the previous play. 13. b1c2  13... c7c6 [%c_effect c6;square;c6;type;GreatFind;persistent;true] Attacking the pawn on e4 and also preparing Qa4.
