I have to agree with ilikeaces86...when you bet and check here you're chances of winning are higher if you are in position. 1- they could all fold. 2- you'll be heads up or 3-way with good chance they check to you. 3- if you hit the flush on either card you are less likely to get pegged on your cards and ups your implied odds greatly.

Some other advantages are that if no one raises they are probably on a draw or slow playing. Either way they will likely check the turn. This play doesn't hurt too bad if you have to let it go and could pay off huge if and when you do hit. And who knows maybe pair the ace and call anything affordable.
