Magnus chose to play the Slav and got punished. It is no surprise that Wesley played the Exchange Variation, because it suits his zero-risk-style, it also contains a bit of venom. If black plays for a win he usually gets in trouble very fast. I am not going to add any pointless computer analysis to the game. If you are interested, you should check out Svidler’s commentary on Youtube, that is if you survive the mild monotone voice and his human-tranquilizer-style for more than two minutes. Unfortunately I can’t, which is arguably very sad.
Play it safe!
