XI Aberto do Brasil – Taça Cidade de Teresina 2026 will take place from August 14 to 16, 2026, at Blue Tree Towers Rio Poty.

Moreover, the tournament will use a six-round Swiss system. Digital-clock games use 90+30, while the regulations provide a 120-minute knockout alternative for analog clocks.

In addition, the Brazilian and international rating status gives players a full national-open experience across three days.

Meanwhile, the hotel venue combines the playing hall, accommodation, restaurant facilities and a central Teresina location.

Therefore, participants should confirm CBX registration, entry fees and hotel conditions with the Piauí Chess Federation.
