Fold AQs to a raise preflop
If the first bullet gets called, don't fire a asecond without a read
Don't call of your stack with TPTK
Do fire a CB if one overcard to your pocket pair flops with a small field. Do not fire into two overs.
Do not slowplay unless villain is a maniac
If you know you've been rivered take a deep breath and press Fold
When you flop a weak ace from blind bet the flop, then check/fold every other street without a read

Anything that I am missing? I play theoretically much, much better than I play in practice, hopefully this will help a little
