Filipino teen chess whiz Wesley So remained in contention at the 71st Corus Chess Tournament by beating International Master Roeland Pruijssers of the Netherlands in the tenth round Wednesday (Thursday in Manila). The competition is being held in Wijk Ann Zee in the Netherlands.

A report posted on BilliardPhilippines.com said So prevailed after 47 moves of a Sicilian Defense to remain in solo second with 7.0 points on account of five wins, four draws and a loss.

The 15-year-old Filipino Grandmaster (GM) is just half a point away from GM Tiger Hillarp Persson (2586) of Sweden who defeated German GM Frank Holzke.

It was Holzke who gave So's first loss in three top-level tournaments.

So's last three remaining opponents are IM Manuel Bosboom of the Netherlands, David Howell of England, and Persson.
