How strong do you like your tournaments? How does an average rating of 2793 sound? The inaugural Sinquefield Cup was held in St. Louis, USA this September, and IM Danny Rensch and GM Melik Khachiyan deliver the action. Khachiyan used to coach one of the players, and you can probably guess which one. Watch Carlsen, Aronian, Nakamura and Kamsky play the opening round of this historic tournament, the strongest ever on American soil.
