Playing black in the opening round of Gupta made many unforced errors in the middle game to find himself on the wrong side arising out of a Sicilian defence and was outdone as the Chinese came up with some fine resources to draw the curtains during yesterday's encounter.
The highest rated Indian Grandmaster in the fray, B Adhiban however had little difficulties in toppling the defense of Shamsiddin Vakhidov of Uzbekistan.
Adhiban was in his elements in tackling a Queen pawn game with white pieces and his attack came good with pawn sacrifice early in the opening.
Vidit Gujrathi also got off to a flier giving a positional lesson to his lesser known opponent Bakhodir Kholmirzaev.
It was another Queen pawn game of the day wherein the Indian played black and after initial discussions seized the initiative with some deft manoeuvres. The heavy pieces endgame was slightly better for Gujrathi who first knock downed a pawn before wrapping up the game.
Amongst the Indian favourites, SP Sethuraman was the other winner with white pieces against Arif Abdul Hafiz of Indonesia. The Queen pawn opening led to a slight better position and Sethuraman was at his technical and tactical best to convert it in to a full point.
In the women's championship being held simultaneously, Padmini Rout started off steadily with a fine victory over Asian junior girls' champion Uuriintuya Uurtsaikh of Mongolia.
