Mumbai, Oct 4 (PTI) India's top players enjoyed mixed luck in Round 4 of the World Youth Chess Championship, with R Praggnanandhaa scoring a comfortable victory and P Iniyan eking out a tough draw even as Divya Deshmukh suffered an upset defeat here on Friday.

FIDE Master Srihari L R was the dark horse of the day, shocking top-seed FIDE Master Sreeshwan Maralakshikari in the Under-14 Open category.

GMs Praggnanandhaa and Iniyan topped the points table in the Open Under-18 with 3.5 points each, along with IM Aryan Gholami of Iran.

Praggnanandhaa, who had endured an exhausting draw in Round 3 against IM Artur Davtyan of Armenia, recovered smartly to beat IM Nikoloz Petriashvili of Georgia.

He opted for the King's Pawn Opening, which was countered with the popular Sicilian-Defence by Davtyan.

After a complex middle-game, the Indian swiftly outplayed him in the endgame in 40 moves to take home an important point.

Iniyan, however, could not emulate Pragg, but will be happy to hold a higher-ranked Gholami.

The country's other hope and top seed in the Girls U14, IWM Divya Deshmukh, who also had to be content with a draw on Thursday night, suffered an upset defeat to slide down on the leader-board.

She lost to Mongolia's Woman Candidate Master Bat-Erdene Mungunzul.

In a London System game, Divya failed to obtain any tangible counterplay even as Bat-Edene'S double bishops reigned supreme on the board.

This led to a blunder by the Indian, leading to her resignation on move 45.

Indian IM Aditya Mittal (Open) U18 and Lakshmi C (Girls U16) were the stars of Round 3 on Thursday, with the former drawing against top seed Sargsyan and the latter scoring her second straight upset against Serbian Woman FIDE Master Jovana Srdanovic.
