KOLKATA: Three Grandmasters, Sergei Tiviakov of The Netherlands, Tigran Petrosian of Armenia and Alon Greenfled of Israel, jointly led the field with three points each at the end of the third round of the Kolkata Open international chess tournament at the Gorky Sadan here on Tuesday.

Top-seeded GM Tiviakov opted for the Scandinavian defence against IM elect G.N. Gopal. The Dutch managed to get the better pawn structure and exploited the position by picking up the weak pawns of Gopal in the endgame.

Attacking game

Fourth-seeded Petrosian played an attacking game against GM Niaz Murshed of Bangladesh. The Armenian broke through on the kingside forcing Murshed to give up his knight to save what looked like an imminent mate. Eventually, GM Petrosian's extra material proved decisive.

GM Greenfeld proved too good for local IM Raktim Bandopadhyay. Playing with the white pieces Greenfeld got a queenside attack going and won an exchange. Bandopadhyay tried to come up with some counter-play on the kingside but his efforts proved futile.

GM Darmen Sadvakasov of Kazakhstan stopped giant-killer and under-13 National champion Vidit Santosh Gujrathi. The GM won a pawn against the 12-year-old and thereafter showed flawless technique to pocket full point.

FIDE Master Vidit had beaten two higher-rated opponents in the first two rounds.

IM Sundararajan Kidambi, with white pieces, put it across IM Rahul Shetty in 25 moves in a Queen's Indian Defence.
