The Grandmaster Triathlon began on Sunday in Biel with the discipline of rapid chess. After five games of rapid chess the two favourites, Vladimir Fedoseev and Aravindh Chithambaram (pictured), lead in the Masters. Wojtaszek, the 2020 Biel winner, is lurking just behind them. Theodorou took the lead in the Challengers, remaining undefeated, as did his closest rival Hakobyan. GM Benjamin Bok won the open rapid one-day-tournament. The Dutchman prevailed against 149 competitors ahead of GM Mikhail Kobalia and Chen Yuan. | Photos: Biel Chess Festival
