Mamedyarov played a very rare system which he already used in a game against GM Brunello in Porto Carras, 2011. Black made a novelty on move 6 and got a very active position. Had white castled on move 16, his problems would have been less visible. Instead of 19.e4 which was a mistake, he should have just taken the pawn on b4, after which even if Black is a little better, white has a good play.
