So after 4 games the match is tied 2-2, which was the same score in the 2013 match. However in that match all the games were drawn, while so far this match has shown both strengths and weaknesses from both players. If there is going to be change in the rest of the match, it may well come from Carlsen's openings, as the perception is that he has not been focussing on tht part of the game as strongly as Anand. So far the idea of getting a playable middle game has been good enough, but he may need to take that extra step to ensure he keeps his title.
