The Aeroflot Open concluded with a surprising but well-earned victory for Belarusian grandmaster Vladislav Kovalev with 7.5/9. Along with the $22,000 first-place prize, he now earns a spot in the Dortmund Super Tournament later this year. The event had many interesting occurrences. Only two of the beginning top 10 players finished in the top 10, with the top seed, Vladimir Fedoseev, finishing 46th and second-seeded Vidit Santosh Gujrathi ending up in 35th. The Iranian contingent of four ended up with two new grandmasters, 14-year-old Alireza Firouzja and 17-year-old M. Amin Tabatabaei.
Today’s game features young Tabatabaei and Fedoseev, which was chaos from the get-go. Fedoseev seems to have the reputation for enjoying unusual positions and for not being a very solid player. This game supports both of these thoughts. Tabatabaei responded very well to the Russian’s unsound provocations, but just when he could secure a winning advantage, he got cute and then was forced to basically sue Fedoseev for peace with a perpetual check, which to Fedoseev’s great regret he turned down and then went on to lose badly.
