hmm, i have a few

fold kq to any pf raises in a higher limit game that isn't full of retards

stop calling All-ins with vulnerable hands (big one for me today)

never underestimate the power of stupid players, you need really good hands to take them down

don't worry about pot odds so much, if you're beat, and you know it, fold.

when in doubt, raise

bluffing big pots in cash games is a good way to lose chips (unless of course you've laid down some monsters before this, DONT BLUFF)

learn the difference between aggression and bluffing, theres a fine line
