However just because it is a surprise, doesn't mean it is going to work every time. Following Carlsen's lead, Karjakin used it against Michael Adams in round 10 of the same event, only to end up on the wrong side of the win/loss column. To be fair to the opening, after move 20 things seemed to fine for White, and optically White's attack looks stronger than Black's. Where it really goes wrong for White is at move 25 where Karjakin's plan to run his king to safety on the kingside ironically makes it less safe, as the queenside needed an extra defender to hold it together, that being the White king itself.
