The event was organised after the 44th Chess Olympiad was postponed due to the COVID-19 pandemic.

The final match between Russia and India was called off after several Indian team members experienced connectivity issues due to a global outage of Cloudflare servers; Russia and India were subsequently declared joint winners.
