Anand had recent experience in this line as he won a nice game against GM Ding Liren, but this time he deviated on move 14 by choosing the seemingly sharper 14.0-0-0.
The pair of knights were exchanged in the center and then Carlsen advanced his Queen to d5 offering another trade.
To the surprise of the commentators and audience alike, Carlsen decided to accepted the trade instead of continuing to press with 18.Qg4.
