Set in southern Brazil, the RS Chess Open 2026 runs June 4-7, 2026 in Porto Alegre, Brazil and delivers a full classical Swiss program with FIDE and CBX rating on the line. The event schedules seven rounds at a steady classical pace with 90 minutes plus a 30-second increment, and it complements the main tournament with a rapid doubles event and an optional blitz event. The organizer offers a published cash prize pool and uses clear competitive tie-breaks, which makes this tournament attractive for ambitious club players and titled participants who want serious games and meaningful incentives in one long weekend.

The organizer also links this tournament to the Brazilian competitive pathway by allocating 30 qualification places for the national championship final and by counting results toward CBX title point requirements for Mestre Nacional and Candidato a Mestre. You register online and confirm your entry through PIX payment, and you benefit from early registration discounts before the late-entry increase. The schedule starts with an opening ceremony and a late-evening Round 1 on Thursday, then it drives the event forward with two rounds per day until the Sunday finish.
