The other higher-ranked players also cruised to the second round and topping the list was reigning world champion Yifan Hou of China who scored easily over Sachini Ranasinghe of Sri Lanka.
The Sub-continent girl had missed her flight and reached here only thanks to some deft planning at the last minute but the match against Yifan turned out to be one sided.

Humpy faced the Slav defense and stuck to basics in the opening to get tangible advantage. As the Indian girl posted her knight in the center, Denise blundered a couple of pawns and was never in the game. Humpy finished the proceedings in just 26 moves.
Harika made use of her white pieces to good effect against Soumya in an English opening game. After attaining a playable position in the middle game, Soumya went wrong with an erroneous plan and handed Harika initiative.

The USD 450000 prize money Championship will be reduced to 32 players from 64 in the next round and more fighting matches will ensue in the rounds to come. Those who return home after the first round will be richer by USD 3000.
