Villain is 16/5/2.5 after 140ish hands. Called preflop because UTG is 48/17 and looks like a spewball. I usually would raise this flop heads up but was giving him credit for a big hand that probably isn't folding, based on his lead into a multiway pot and into the preflop raiser. Do you guys raise this? Call down as far as I did? Comments all over please.

i insta fold turn. Dont think u have much implied odds against a nit. Unless hes a nit fish Id foild it all day!

Flop seems like a nice and easy raise. If he dont have a top pair hand, he will prolly go away. If he has, we have some nice outs against him.

As played, fold turn as icheckcallu says.

I think you could fold a lot of better hands by raising flop (and have an easy fold if he 3 bets) but as played I'd let it go on the turn.
