I just got back from an AC trip playing $1/2 and $2/5 NLHE and learned a few important lessons about live poker.

1. Never play tired. It's like burning money.
2. Table selection is not important. All table have 2-5 decent players, 0-2 sharks, and the rest are fish.
3. Seat selection is critical. Never sit to the right of a good LAG. No matter how badly you are crushing the table, all of your money will end up in his stack.
4. When in doubt, fold to aggression. 80% of your opponents are tight passive or loose passive. The moment they get aggressive, you're crushed. (This is by far the most important bullet point.)
5. Whatever the obvious hand is for your opponent, that's what he has.
6. 3xBB raise pre-flop is the same as calling. Nobody folds to anything less than a 4xBB raise. Therefore, always raise 4-10xBB pre-flop (depending on limpers). You'll get plenty of action.
7. Nobody pays attention to pot odds. A $35 bet into a $20 pot is viewed the same as a $35 bet into a $100 pot.
8. Nobody folds a pre-flop monster, regardless of post-flop board texture. Your money will be made by cracking aces and kings, not by getting aces and kings.
9. Suited connectors and small pairs are the best possible hands pre-flop (see previous point).
10. Women are ultra-tight. Any woman that is not ultra-tight is a shark.

Thoughts? Clearly all of this advice is useless against sharks. Against sharks, simply play your game (for me, that's LAG from late position and TAG from early position, i.e. positional poker).

I'll post some specific hands from the weekend later.
