When the best in the world actually has to play defense, he does it pretty well! In the game McShane-Carlsen, London Classic 2011 the "world's greatest amateur" had the world #1 on the ropes, but when Magnus puts on a defensive clinic (clearly recognizing white's plan as well as which pieces to exchange and when/how to exchange them) the young Englishman is unable to crack black's blockade. Enjoy GM Shankland's review and take more notes on how to play defense!
