Another Min Raise: Straight on a flush board

[beset7]

Villain is 59/10/3. His aggression factor on the river is 6 (!?!).

These situations never fail me to trip me up. Whats your line. I think I fold to many winners here and push to many losers. Any input, standard lines, suggestions would be appreciated. Thanks.

why bet the turn?

presumably this guy will raise you with not just the flush here but the question is are you willing to call his turn raise with just the straight?

if the answer is no then I don't like the turn bet.

What do you suggest? Short-handed I want to take it down right now and don't want a lone club drawing and yes I'm willing to call the raise most of the time which might part of the problem. I actually considered three betting.

edit: Call me crazy, but I can't think of any lines I like that involve checking the turn. Play the whole hand out for me if you check the turn. If you've got a good plan it could save me some dough.

so who is going to come out and say they check/fold the turn. i want to hear you say it.
