<Whitehat1963> I might be a bit worried if he turned up at a tournament with a giant silver robot named Vlastimil Hort


Mr Datu is not a player I know much about.

2000 Istanbul Chess Olympiad:

On the eve of important last round match versus Latvia, Philippines' IM Idelfonso Datu was stricken with an ulcer attack and was immobilized the whole night. Since the pairings had already been submitted, it was either drag him to the playing hall or forfeit the game. Philippines' Board 6 Ronald Bancod half-carried him to the tournament venue and sat him opposite IM Meijers on Board 4. Although very pale and in cold sweat, Datu massacred the Latvian…really an inspiring sight to behold!!!
