PBG Alaskan Knights defeated Ganges Grandmasters and are now only one win away from the Global Chess League final with three more matches remaining before the knockout stage.

But finally, Carlsen threw in the towel against Maxime Vachier-Lagrave and exited the playing hall in a huff. What made matters worse was that his team, the Alpine SG Pipers, lost 5-14 to the upGrad Mumba Masters with defeats for Richard Rapport and Daniel Dardha.

The $1mn Tech Mahindra Global Chess League, which has brought world No 1 Magnus Carlsen and many other top grandmasters to London this week, reaches its final on Saturday. The franchise-based six-team league has already sparked controversy.

Alaskan Knights maintained their unbeaten streak by defeating Magnus Carlsen's Alpine Sg Pipers 9-7 in the Global Chess League, despite Carlsen winning against Anish Giri. Key victories by Nodirbek Abdusattorov and Tan Zhongyi secured their lead.

The Mumba Masters bounced back decisively to climb from the bottom of the standings to fourth place, just behind the Pipers, with a 14-5 win on Tuesday.
