Georgia's Levan Pantsulaia defeated tournament leader and fellow GM Maxim Lugovskoy (Russia) in the ninth and penultimate round Thursday to snatch the lead with eight points in the 11th Chennai Open International Grand Master chess tournament here.

Tamil Nadu lad M Pranesh shocked GM Erigaisi Arjun, thereby achieving his International Master Norm in style. Requiring a draw to achieve the norm, he defeated Arjun in a Sicilian game that lasted 62 moves.

Earlier, tournament leader Lugovskoy went down to in-form Pantsulaia on the top board.

Employing the "c3" Sicilian, Pantsulaia grabbed the initiative with original middle game play.

The sheer energy he brought into his pieces undid Lugovskoy, who lost the plot in a rook and pawn ending.

Saurabh Anand continued his good form, as he brought down International Master P Shyaam Nikhil, increasing his norm chances.

The tournament concludes tomorrow with the 10th and final round.
