this is very similar to a hand I posted a bit earlier (I had pocket JJ, A came on the river). The big difference is in my hand, I had position, so I checked behind. In this hand you are acting first, and I think it is generally the best line to bet with few outs and check with outs. You have few outs, so I think bet/fold works better. As many mentioned, it makes it a bit more costly for villain to bluff you out of the pot
