Going into the final round of the tournament, Alireza Firouzja had the chance to tie for first with a win in his final game. However, due to the tournament's tiebreaker rules, he would be unable to compete for first place even if he finished with the same number of points as the tournament's leaders. In his final round matchup against Radosław Wojtaszek, the arbiters suggested mid-game that the two move to a different table, irritating Firouzja. The situation generated controversy, with many players supporting Firouzja and claiming that arbiters shouldn't interrupt games in such situations.[3] [4] [5] and the event organizers ultimately apologized.[6] [7] The game ultimately ended in a draw, and Firouzja placed fifth in the tournament with a score of 8/13 (+4-1=8). Firouzja accepted the organizers' apology, but demanded a financial compensation for the incident as part of negotiations for his participation in 2022. His demand was turned down, and Firouzja didn't participate in the 2022 tournament.[8]
