GRANDMASTER Oliver Barbosa shocked GM Kiril Georgiev in board two, leading the Philippines to a 2.5-1.5 victory over Bulgaria in the sixth round of the World Chess Olympiad in Istanbul, Turkey.
Barbosa, with an ELO rating of 2554, forced Georgiev, holding an ELO rating of 2682, to resign after 57 moves of a Slav encounter to grab the Philippines’ lone win over Bulgaria.
With the stunning victory, the Philippines moved up to fifth place after winning for the fifth time in six rounds as they trail only Russia, Armenia, Azerbaijan and China.
The Filipino woodpushers sealed the win with draws by GMs Wesley So, Eugene Torre and Mark Paragua.
So halved the point with GM Veselin Topalov in board one; Torre drew with GM Ivan Cheparinov in board three while Paragua forged a truce with GM Alexander Delchev in board four.
The Philippines will face Hungary in the seventh round.
In the women’s side, the Philippines bowed to France, 1-3, to remain mired in 31st place.
WIM Catherine Perena was the only winner beating IM Almira Skripchenko in board one.
WNM Janelle Mae Frayna lost to IM Milliet Sophie in board two, WNM Jedara Docena was beaten by IM Silvia Collas in board three and WNM Jan Jodilyn Fronda was outclassed by WIM Andreea Bollengier in board four.
