There are three players with this title, Alexis 'J0hnny_Dr@m@' Zervos , George 'gkap13' Kapalas and Stavros 'IDOLLS' Kalfas. All three players are from Greece.
According to Zervos' reply in the thread:
this is a new concept by pokerstars in order to determine which player from greece can make team pro we have all been offered a sponsorship and according to the results in 2011 best performer will be awarded team pro status...So it seems one of the three Greek poker pros will be chosen to become a member of PokerStars Team Pro. The details haven't been made public but it seems they will be counting online as well as live results and more. I'm guessing that we'll see blog updates or a web page tracking their progress soon.
In 2010 all three did well in PokerStars tournaments. Here were their results.
PokerStars has also started the Greek Poker Cup, 'the first-ever major poker tournament on Greek soil'.The event will be held at the Club Hotel Casino Loutraki, the largest casino in Greece.
Seems like this was a good market to target based on what I've seen so far. If you're Greek and you haven't created a PokerStars account yet click here to join the fun!
