Eesha took her tally to three points and is now in strong contention for her third and final International Master norm.

The other Indian performer was M R Lalith Babu, who accounted for higher-rated IM Al Sayed Mohamad of Qatar while GM R B Ramesh had it easy against Egyptian El Arousy Abdul Hameed.

In a minor upset of the day Sharif Mehrshad of France held highest-rated Indian GM in the fray, Koneru Humpy, to a draw after a hard-fought battle.
