In the boys section, playing on the first table with white pieces, yesterday's leader Saptarshi opened the game with king-pawn against which Y Sonwani of Madhya Pradesh opted for Sicilian Defence. In the middle game, Saptarshi won a pawn and commanded the board, but later he mishandled the situation to allow to escape his opponent with a draw. While on second table, top seeded Venkatesh had gained superior position in the opening from the Pelikan variation of Sicilian Defence of S Poobesh Anand (TN). On the 25th move Venkatesh won a pawn and brought home the advantage to score a full point after 49 moves.

In the girls section, playing on the top table with white pieces Anuradha had a lucky escape against R.Mahima of Tamil Nadu in the Sicilian-Pelikan Defence game.
