What is the best things to do in cash games ??
Or to not do...

I believe in cash games the worst thing you can do is getting caught bluffing and playing most of hands. One of the most important things in my opinion is gaining respect at the table and you don't get that by bluffing or going all in like a maniac. Hope this helps. Good luck

I agree with whats stated above . I would say once people respect you the fear you and you can semi bluff a bit more but if you see something test it, you have to beat both the machine and the player on online poker
