Indian Grandmaster Vidit Santhosh Gujrathi lost his seventh-round game to Jorden Van Foreest while world No.1 Magnus Carslen got the better of R Praggnanandhaa to claim the lead position in the prestigious Tata Steel Masters chess tournament here.

Van Foreest introduced an interesting novelty on the white side of Nimzo-Indian Defence against one of the leaders, Gujrathi and an error by the Indian GM on move 36 proved costly as the Dutchman capitalised to post a win late on Saturday.
