The first big post Olympiad event has just begun in Moscow, the 2016 Tal Memorial. This 10 player round robin is a little light on the top 10, but the assembled field are all rated above 2700, and the organisers have tried to invite exciting/attacking players.
Top seed is Vladimir Kramnik, and with Anand, Aronian and Mamedyarov in the field, it looks to be a hard fought event. Mamedyarov got his tournament off to a good start, winning the opening blitz event with 7.5/9, and getting to choose his seeding number.
The main event started a few hours ago (Canberra time) and while I'm watching it through chess24, the tournament website is here.
