Magnus Carlsen has won the first match of the Aimchess US Rapid final against Vladislav Artemiev in spite of losing one game due to a curious mouseslip. The world champion got doubts about his planned move and dragged the queen back to its original square to think more. Only when he wanted to move a minute later, he realized that a queen move to a square in between had been registered and that it was Artemiev’s turn. (Update:) Of the other games in the final Carlsen won four, drew two and lost none, scoring a clear victory and $30,000. Alireza Firouzja defaulted the match for third place in order to recover from being unwell before he travels to Stavanger for Norway Chess.
