If you're new to poker and you want to try a live game, try playing online poker first.
It's not quite the same as a live poker game, but the cards come out about the same way in online poker as they do in live poker.
After you've had several or many hours of online poker play under your belt and you've learned how to play poker, then try the live games.
To get a hands-on experience before you hit a table, you can also try what most casinos offer; free poker lessons at one of their tables.
Most of the larger casinos offer game lessons for free during certain hours of a day.
The best thing to do is contact a casino floor manager and ask them directly if they offer free poker lessons.
If they do, then go to one, get your first hands-on live poker lesson, and learn the basics of live poker play. And then go for it.
As I've mentioned before, practice makes perfect...or at least a better poker player if that's the game you're playing.
