At this point in space and time we can barely speculate who is hiding their true identity behind the screen name "long90110" on PokerStars.
My intuition told me that it could be one of the actors from that old Beverly Hills TV Series. I mean, they had really rich parents to begin with, and they made close to 300 episodes, and didn't spend anything on alcohol. At all. So they should still have some money left. After a few days of intense research, I found out that their area code is in fact 90210, and my theory goes out the window.
Seriously, this is what we know so far, he or she registered the account in Macau (the Monte Carlo of the Orient) where they hold some of the biggest cash games on the planet.
This player started playing PLO $25/50 and $50/100 in September 2009, and not much happened during the first two months, swings of $6K is nothing at those stakes.
long90110 ended the month of November down around $65K in total, but then in December he or she suddenly starts playing deep staked $200/400, and whenever this was the case, the waiting list to those tables were longer than usual.
