INTERNATIONAL MASTER Master Wesley So demolished No. 63 Tigran Mamikonian of Armenia Friday to pick up his third straight win in the 2007 World Juniors and Girls Chess Championships at the T. Petrosian Chess House in Yerevan, Armenia.
So, who turns 14 on Oct. 9, essayed the Bishop Opening with the white pieces to record the victory in 51 moves.
A dubious knight move by Mamikonian on the 30th move allowed So to win a pawn, enough to win the endgame.
So is tied for the lead with Grandmaster David Howell of England and third seed GM Maxim Rodshtein of Israel, his fourth round opponent.
Rodshtein dumped IM Evgeny Romanov of Russia in 41 moves of a Gruenfeld Defense while Howell took the measure of IM Gogineni Rohit of India.
Bunched with 2.5 points apiece were top seed GM Wang Hao of China, GM Ivan Popov of Russia, GM Arman Pashikiran of Armenia, GM Victor Laznicka of Czech Republic, GM Gawain C.B. Jones of England, GM Georg Meier of Germany, GM Parimarjan Negi of India, IM Narayanan Gopal of India and IM Sasha Kaplan of Israel.
