Negi, who played white, and So have a rook and four pawns each when the game was drawn by perpetual check.

Although the match lacked the expected fireworks, the Negi-So match drew a lot of attention in the international chess community since it pitted two of the world's youngest grandmasters.

Negi became the world's second youngest player to earn a GM title at age 13 years, four months and 22 days, while So was the seventh youngest at age 14 years, one months and 28 days. Both are also 16 years old.

Chessdom.com live game analyst GM Buenaventura "Bong" Villamayor said So held a slight initiative against Negi, who had to battle his way with a fractured pawn structure on the kingside.

But the Filipino champion failed to find a way to sustain the pressure against the hard-defending Indian hero with less time on his clock. Negi minimized So's attacking chances when he forced an exchange of the queens on the 15th move.

"The queen exchange on 15. Qf3 fractured Negi's kingside, but So's attack was minimized. Now, So had to find ways in maintaining his initiative...not easy with less time," said Villamayor, the only Filipino player invited to join the Chessdom.com team analyzing the games in Corus.

The draw was the fourth in as many matches for So, who earned an invitation in this tough, category 16 tournament (average rating ELO 2629) after topping Group C of the same tournament last year.
