Indian Grandmaster R Praggnanandhaa's winning run came to an end at the hands of China's Quang Liem Le in the fifth round of the FTX Crypto Cup, the American finale of Champions Chess Tour, here.

Liem Le scored an emphatic 2.5-0.5 win over the teenaged Indian GM, securing victories in games two and three after the opener ended in a draw.

A 43-move win in the third game sealed the deal for Liem Le as Praggnanandhaa's stupendous run was halted.

World No.1 Magnus Carlsen, meanwhile, went down 2-4 in a tie-break to Jan-Krzystof Duda of Poland after the four-game match ended 2-2.

The Norwegian is in sole lead after the fifth round with 13 match points, one ahead of Praggnanandhaa.

The 17-year old Indian prodigy has been in superb form in the tournament, scoring wins over world No.4 Alireza Firouzja, Anish Giri, Levon Aronian and Hans Niemann before the Chinese GM halted the streak.

Praggnanandhaa's coach Ramesh said after the player's first defeat, "Tough loss for @rpragchess against Liem losing with a score of 0.5 - 2.5. Over extended in second game and paid the price. Well done Liem!" In other matches in the round, Firouzja beat the winless Niemann 2.5-0.5 to close in on Carlsen and Praggnanandhaa with 11 match points.

Dutchman Giri beat Levon Aronian 2.5-0.5 to move into 5th place with 7 points.
