Well, I don't know who it is. But I think that Olivier Rochus used to play doubles with that guy. He was probably also in the AFT center in Mons. I'll try to find his name somewhere in my memory.
Fred, who's working with me at my site, helped me. He remembers the guy playing doubles with Oli at that time (in the ETA -14 events): it was Thomas Berton. He was one of the best by the -14 but never confirmed. Today's he's B-15 and plays in chapelle-lez-Herlaimont. Born on 11/4/81. Picture is probably from Les Petits As 1995.
If you want to be sure, send the picture to the responsibles of his club
