Aeroflot Open

The Aeroflot Open is an annual open chess tournament played in Moscow and sponsored by the airline Aeroflot. It was established in 2002 and quickly grew to be the strongest open tournament. The first event had around 80 grandmasters, while in the second event 150 grandmasters participated. The tournament is played using the Swiss system and the winner is invited to the Dortmund chess tournament held later in the same year, a tradition begun in 2003. In recent years there has also been a B and C-class tournament.
