I don't mind betting to atleast beef up the pot or take it down right there. For example, if I have a flush draw and its 15/30 and the pot is 180 w/ 2 or maybe 3 other players, I might make a bet of about 45-60.
I do this because, in the micros, I will pick up the pot a decent percentage of the time right then and there to make it profitable,... the other percentage of the time, I'll hit my card right after against maybe 1 other caller. From there I'd try and get value... Then, of course, another percentage of the time I'm up against a player I think might not have much at all and would fold to a bigger bet and I would then be picking up a much more profitable pot.
This doesn't work all the time, and I pick and choose when I want to do it (whether or not I'm up against players who trap/slowplay a lot or maybe are aggressive) so I might just take a free card.
