I also go back and forth here against unknowns. If I raise I normally do it on the flop and if they lead the turn again dump it. I am probably giving up something against an unknown because you do encounter an idiot with 55 or J9 here ocasionally. It just sucks so hard to raise the turn and get lead into again on the river that I try to avoid it against a total unknown, unless I'm going to welcome that river lead.

People who lead into me on every street make me want to kill things.
