Post-flop:
I. Aggression is king in poker. Betting is always better than checking. If you get re-raised and you're pretty sure you're beat, or have nothing at all, simply fold. It's not wasted chips, it's just the way the game is played. Once you're a better player you'll know when not to bet and how quickly to fold and whether you can steal the pot with nothing but air from shier players and so on.
II. Learn player types. Helmuth describes the Elephant, the Jackal, the Mouse, and the Lion (as well the as the Eagle, which is an elite pro and irrelevant to us).
The Elephant never folds, but also never bets, so you're never quite sure where he stands; this is also called a calling station. Never bluff this player; and when you have the nuts, squeeze as much out of him you can. Too much and even an Elephant will flinch.
The Jackal will play every single pot as aggressively as if he has pocket aces. He'll shove pre with air. He's completely insane. When you raise with a good hand he'll almost always three bet you regardless of his cards. When you encounter this player rejoice, you're about to be rich. I shouldn't need to explain how to take advantage of him.
The Mouse never plays unless he thinks he has the best hand, pre flop or post flop. If you thought you had a good hand but the Mouse calls before or behind you, get out of there fast. Never call his raises unless you have the nuts (you won't, because he will).
The Lion is just a very good, aggressive player. He mixes his bluffs and value bets well, so it seems to fish like he's the luckiest player ever since he seems to win every pot. He also has an uncanny sense for when he's beat and can comfortably lay down great hands that lesser players would get fleeced over. Avoid tussling with a lion until you're one yourself or you have the nuts.
