Vachier-Lagrave probably forgot his preparation. The idea is to defend the g7-pawn and prepare ...Bc5. 19. f3e5 [%c_effect e5;square;e5;type;GreatFind;persistent;true] White has other good moves, but I like Carlsen's choice. 19... f8c5  20. d4e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] This is the point. 20... d5e4  21. e5d7  21... d8d7  22. d1d7  22... e8d7 Positions with a material imbalance are difficult to evaluate. White has the advantage, but the position is tricky. 23. b2c4 [%c_effect c4;square;c4;type;Mistake;persistent;true] 23... g7g5 [%c_effect g5;square;g5;type;GreatFind;persistent;true] 24. f4e5  24... d7e7 The position is unclear now.
