I love to bet with my flush draws, especially the ace high ones. This is the only way I can get paid off. If I call then I might have to draw against odds. If I finally do make my flush then everyone knows it and no one will call my bets. I say bet 1/3 to 1/2 pot size from middle to late position. Alot of times people that were planning on betting will just call a medium sized bet and you well get better drawing odds to make up for the times when an aggressive player behind you re-raises hard and you have to drop you hand. The times you don’t want to bet of course is when someone else bets for you and gives you good odds to draw. Depending on the feel for the table you usually don’t want to pansy bet from early position into a lot of aggressive players because they will re-raise you and make you drop it.

I agree with the lemmings part too. Sometimes people will bet small with their top pair or whatever they have and give you good odds. Might as well call these guys if they bet from an earlier position than you. If they check the turn then give them back another pansy bet in which case they will normally call or you can try to semi-bluff with a 3/4 pot-sized bet depending on the player.

Also, when you make you flush always pause for just a bit to make it look like your thinking because your scared of the card then make a large enough bet to make it worth your while but one that won't scare them off. An alternative is to very weakly bet when there is a big pot in the hopes that they will try to bluff you out. This can be a big payoff when an aggressive player goes all-in. This of course only works well when you have been the aggressor.
