What I meant to say before was that you should always bet the flop if you have just raised normally to maybe 4 or 5 bbs before the flop. However, when the pot has been re-raised before the flop comes out then it is already very big. In this case you don't need to bet to make him fold because he more likely has a hand and the pot is really big anyway.

The only excpetion to this is when we miss the flop in full. In this case we can bet 10% - 15% of the pot to try and make him fold sicne we probably wont win the hand if we do not bet.

If our hand has any potnential or is strong we never bet in the big pots unless it is the nuts hand. In small pots we must always bet so he can't bluff of or win with ace high or something when we have a king or queen hand.
