X/r pre with premium cards. Make it big. If someone opens to $15 and there are 4 callers, then your x/r should be > $100.
Play lots of speculative hands when in position if you can do it cheaply. In short don't tighten up, but use position effectively.
Play for stacks at all times. Do not see a turn unless you intended to get stacks in.
Overbet big for value. 1.5x pot at least.
Stop slow playing.
Stop bluffing. Just don't bet unless you have it.
Do not show your cards.
Lol, do not table change...
