The Rubinstein Chess Festival 2026 opens in Polanica Zdrój with Round 1 underway. Poland's prestigious Open A section kicks off with a 9-round Swiss format, giving players 90 minutes plus 40 moves, then 15 minutes with a 30-second increment. The classical time control attracts serious competition hunting rating points and the tournament's prize fund. Early results should clarify which players came prepared versus those still shaking off rust after the holidays.
