The first thing you notice is the selectiveness of poker players in a casino. The other thing you notice will be, speed.

The dealer will always push the pace and a new player will take time to adapt. A new player will be startled by the speed. But once you get use to it, you only have to play recreational players and regulars. The first you will beat blindfolded and the latter you will be able to read them if you play more then once with them. The thing with the regulars is that they want money but don’t put time in studying poker and always make the same mistakes. So if you notice that one mistake you will probably see it again.

If you live in an area where poker has been legalized recently, you shouldn’t have any big competitions locally. Even if you play in a place like Vegas but manage to play with better players and manage to learn and study poker at the same time. Soon you will be winning a few games against them.
