2) Continuation Bets, if you are the preflop raiser, no one has bet the flop in front of you, you should put in a continuation bet assuming the flop is not too wet. Regardless if you missed the flop or not the odds are your opponent missed too. A continuation bet allows you to maintain aggression, initiative, gets value in the pot for made hands, and gives you fold equity against your opponent. There are caveats to this play. Like I previously mentioned, a wet flop is usually not a good situation to cbet with nothing. The likelihood of your opponent having a hand is too high. If your opponent is a calling station or is picking up that you cbet too much you don't want to cbet with nothing. This is a situation where you would obviously bet with a good made hand or strong draw. You also don't want to cbet a multiway bot without a strong hand. You are likely to get called and players will have two more streets to beat your marginal, weak, or non existent hand.
