Former world champion Rustam Kasimdzhanov of Uzbekistan emerged as the new leader in the 14-player round robin tournament after settling for a quick draw with Dutchman Dimitri Reindermann.
The other overnight leader - Fabiano Caruana of Italy also met his nemesis in Zahar Efimenko of Ukraine. Sasikiran got the better of Short, playing white, in a rather complicated game.
An early deviation in the Sicilian defense witnessed Short gaining a spatial advantage and good central control but the Indian kept himself in the hunt with timely counter attacking measures on the king side.
Short missed the thread of the position in the later part of the middle game and Sasikiran won an exchange that proved decisive in the end. It was an overwhelming attack on his king which forced Short to throw in the towel after 35 moves.
