"Boyet" Yap was an orphan who Campo took in as a ward and housed, fed, and clothed. He always gave Boyet odd jobs around chess tournaments, and one day assigned him a job as a "board boy" (someone operating the demonstration boards) during the 1979 Marlboro Chess Classic in Manila. When one of the foreign invitees had to cancel on the last minute due to visa problems, Yap was picked to take his place — apparently because he was the strongest chess player among the staff. Imagine that — from being board operator he jumped to one of the participants in a major (Grandmaster) GM tournament. - excerpt from an article of Bobby Ang 'Chess Piece' which appears regularly in Business World
