Categories: Disability Friendly, ECF Rated, FIDE Rated. Duality is a one-day chess experience built around contrast: deep 20+5 Rapid chess by day, and high-energy Blitz by night. Two FIDE/ECF-rated accelerated Swiss tournaments for all, and a full day of 15 games. Enter one or play both (discounted): each tournament has its own prizes, final standings, and prizegiving, and there will be overall trophies. Our total prize fund is £370+. We’re running Duality at our modern venue, Wyllyotts Theatre: just 20 minutes from King’s Cross by train, and 5 minutes from Junction 24 of the M25.
