Passive play is pretty much never right...

Raise preflop. Too many people try to get cute to hide their hands and they don't get the maximum out of their hands. The thing is, at lower limits, the majority of players are not making reads on you, keeping notes on you, etc. They will not recognize plays by you, so straight forward play will work better.

Bet out the flop. How is folding even a question in your head? You have top pair with the nut flush draw. You are not losing to many hands right now, and you have redraws to vastly improve your hand. How can you really put anyone on a flopped flush or straight here? Even if you did, you'd be right to keep going with your hand. Raise and reraise.

I'd bet/call the turn, with the expectation of check/folding if I am raised and I don't improve on the river. You still have redraw outs if someone has the straight. A raise will also let you see if someone is likely to have you beat.

If just called on the turn, I'm a little hazy on the river. Not sure what's better, check/call or bet/fold.
