“Sergei started working at FIDE events in 2021 and quickly became an integral part of our operations at major international events.
“Over the past five years, he worked behind the scenes at World Championships, World Cups, World Rapid and Blitz, Candidates Tournaments, as well as many events organised by the FIDE Events Commission, including championships for seniors, juniors and amateurs.
“He travelled across the world to make sure these events ran professionally, efficiently and in accordance with FIDE standards.
“Much of this work is rarely visible to the public, but everyone who worked with Sergei knew how much responsibility, energy and care he put into every event.
“Beyond his work, Sergei was also a generous person.
“He supported an orphanage and, wherever his work took him, he would bring back chess memorabilia and small gifts for the children from different parts of the world.
“We will remember Sergei as a true professional, a reliable colleague and a kind person who contributed enormously to the work of FIDE.
