When you try to play the players are you starting with people you play regularly with, or people in casinos?

Practice on regulars. i play with the same group of about 6 people and we play short handed. it is easy to get a read on most of the players. Once you can do this try to take better reads on players you have never played with before in such as in casinos, etc.

But i wouldn't worry about it too much if you are making 40/hr you are playing well.
