Is it more beneficial to bet your flush draw (pocket cards are suited, flop comes 2 cards same suit as your pocket cards) with few people in a pot, or check behind them and see another free card. If you hit your flush you're likely to make more profit if an opponent as well pairs a card. I can see reason to bet and try to take the pot down right their but it can become costly if you get check-raised.

Sometimes I will bet out on a flop that gives me a flush draw to try to set up a check raise on the turn if your flush hits. I don't do this too often though because people will read into your betting patterns. I think it depends wheter you are playing limit or NL. Don't know to much about limit but I think there are some situations where you bet out or even check raise the flop with a flush draw to build equity for your hand.

check it 50% bet it 50% liek aprevious poster said bets it 100% if its 2 overcards. Depend son the players though. Normally I'd bet minumum but sometimes a healthy bet is good. Gives the player the impression you are trying to reduce their pot odds because of the flush draw, essentially representing top pair.

i usually jsut bet it if im in position and its checked to me.
if i have the flush draw with 1 or 2 overcards, i sometimes go for the check-raise (this usually gets u a freecard on the turn)
