They reached the following position after Black played 19..Qe8 to prevent b4-b5

Eventually, they reached the following with white to play
Hikaru played 31 Ne3! the best move of the game. It deprives black from the bishop pair and targets the d6 pawn. Also the knight will jump to c4-a5-c6 which will be hard to defend against, as the dark square bishop is weaker than White's knight
