Be careful...online poker is RIGGED bigtime.
I've played over 1000 sng's, in the past 6 years. They like to keep you playing, so the quicker games move, the more they take on the total rake.
I don't doubt there are a high percentage of poker bots playing for the site, as well.
None of this is regulated by the government, so it's extremely easy to manipulate the profits.
Rigging, is most obvious when you have the chip lead, then get thrown AA, AK, QQ, etc within 10 hands. You hit almost every flop, etc.
Why would they give you money? Much like a ponze scheme, keep the money circulating, to keep you playing, and the rake continuous.
If you look up pokerstars rigged on google, you'll find forum that go into detail on how lopsided the site it. I'm on Full Tilt now, and though there are less bad beats, the rigging is very obvious.
However, through tons of games, I'm a few hundred ahead...that's playing low limit sngs. To put any real money online, you'd have to be very foolish.
