Women Grandmaster Dronavalli Harika regained sole lead after settling for a draw with Alisa Melekhina of United States in the ninth round of the under-14 girls' section in the World Youth Chess Championships in Heraklion, Greece.
Harika now has 7.5 points out of a possible nine and is half a point ahead of her nearest rivals, Anna Muzychuk of Slovenia, Elena Tairova and Melanie Ohme of Germany.
With just two rounds remaining in the event, Harika needs just one victory and a draw to secure the world title.
In the under-12 boys' event, IM-norm holder Parimarjan Negi scored an emphatic victory over Egeniy Pak of Russia to move to joint-second spot.
Zhao Nan of China maintained his top position after a draw with Safarli Eltaz of Azerbaijan.
As things stand now in the under-12 boys, Nan has eight points in his kitty and is followed by Negi and Chinese Ding Liren, who both have 7.5 apiece.
In the next round, Negi will have to tackle top seed Liu Qingnan of China and if the Indian boy is able to win this all-imortant contest, he will again be in contention for the gold.
Meanwhile, things worked in favour of Mary Ann Gomes in the under-12 girls' section. Having been in lead once, Mary defeated Abrahamyan Tatev of United States and moved to seven points.

Arabidze recorded her ninth victory in as many games and now Mohana Priya is in joint second spot on 7 points.
