Vietnam's number two chess player GM Nguyen Ngoc Truong Son finished second behind Italian player Fabiano Caruana at the Biel International Chess Festival in Switzerland that ended Friday.
In the first seven games, seventh-seed Son (Elo 2,617) split points with all the big names including defending champion French player Maxime Vachier-Lagrave and 17-year-old Italian Caruana before beating Anish Giri of Holland and Evgeny Tomashevsky of Russia to take the lead.
However, 20-year-old Son had the same points as Caruana and Maxime, so the latter had to fight each other to play against Son in the final.
Caruana beat Maxime and faced Son in the fight for the championship. In the fast chess decider, Son drew once and lost once to finish second.
The 43rd edition of the Biel International Chess Festival attracted the world's top 10 young players.
He was below other big names like 19-year-old French player Maxime (Elo 2,723), ranked 3rd in world youth rankings; 22-year-old Russian Evgeny (Elo 2,708); and Fabiano Caruana (Elo 2,697) 5th in the world youth rankings.
Along with Son's achievement, it has been a good month for Vietnamese chess, with top chess player Le Quang Liem coming in second at the Dortmund super-GM tournament in Germany a week earlier.
