As for Andrei Istratescu, he has been living in France for several years, after a dispute with the biggest chess cheater ever: Alexandru Crisan.
Wow! From that link I see that manest is IM(soon to be GM) Lenderman. I remember a few years ago, when he was a lowly 2000 player, he got kicked out of the Dos Hermanas tourn on ICC cos he reached the later rounds and only GM's are good enough to do that:-) He's the top player in the USA open circuit now is he not?
