Magnus Carlsen is the sole leader after four rounds at the London Chess Classic. In round 4 the Norwegian beat Gawain Jones with white using the rare 4.Qxd4 in the Sicilian. The game of the round (tournament? Year?), however, was the epic fight between Luke McShane and Levon Aronian. At the end there were two queens for Black and White promoted to a knight! Anand-Kramnik and Nakamura-Adams ended in draws. Wednesday is a rest day.
