I have never made a single deposit on any site in the 20 odd years I have been playing On-line Poker, Sure I have bought into Live game Tournaments in Pub's Club's and Casino's but they are different in that you can see your opponents and watch for visible tell's.
On-line there are thing's that can and do happen all the time, and there is nothing worse than losing Internet connection or having a computer crash on you, causing you to lose the game and money.
Poker is just a game, a game I enjoy playing and if I can play On-line for FREE! so much the better, I use the practice I gain from playing On-line and can go to any Live game and play with some of the best players in the tournament, I have done well playing both On-line and Live Games building decent Bankrolls, Virtually and for Real Cash.
There are a lot of differences between Virtual Poker and Live Games, and if you want to be a successful profitable player you need to adjust your game play, depending on where and when you play, just like you need to change your playing style when you change from Tournament games to Cash Games.
It is an ability I have, so that I can play and win in both types of Poker (virtual and live) and do so playing different formats of the game Like Stud, Draw and Omaha as well as Holdem. Why limit yourself to one form of Poker (holdem) when there are so many different types of Poker out there.
When the fun Stops, STOP!
