I know how you feel. Playing against opponents who, the only thing they know about poker is, that it is important to mix up your game. They will play virtually any hand in any position in a different way every time. So when I play with my friends, I've found that the physical tells
are the only thing I have. For instance how close to them self they put their chips when they bet is a very good tell if they are bluffing
or not. close to them self and they expect to get their chips back. Far away they don't expect to get them back. If they seem confident and slams their chips in the board when they call, bet or raise is often a huge sign of weakness. If they glance at their chips after the flop comes, they probably have a good hand, cause they allready know when the flop comes they want to bet it. Theese are some things you should try to look at, and then forget all about their betting patterns, cause they don't tell you anything. Not alll players have the same tells, but if you try to pay attention to it I'm almost completely sure you will pick up a few tells on all you opponents.
