India, July 3 -- Reigning world champion D Gukesh defeated Magnus Carlsen in the sixth round of Grand Chess Tour, on Thurday. Facing each other in Zagreb, Gukesh has now taken the sole lead with 10 points after defeating the World No. 1.

But then on the 23rd move, Carlsen's decision to push his b pawn ahead to b4, shifted the advantage to the reigning world champion's side.

In the fourth and fifth round, Gukesh beat Uzbekistan's Nodirbek Abdusattorov and American GM Fabiano Caruana, before taking on Carlsen. It was also perfect revenge for Gukesh...
