The Magnus Carlsen Invitational, the first high-stakes online rapid chess tournament, was won on Sunday evening by Magnus Carlsen. The host edged home against Hikaru Nakamura with two wins to one, after clinging on for a draw in a difficult endgame in the fourth and final game. The chess was high level and technical despite the shortened time limits. Carlsen, the clear favourite, was taken to the limit by Nakamura in a tense contest. Both players relied on a hazardous defensive strategy with the black pieces, enabling white to press without much risk. Including their opening encounter in the qualifying rounds, the two traded white wins for seven consecutive games before Carlsen held on at the last.
