(razz) Value raise smooth 8 on 7th?

[RustyBrooks]

Villain is a fish, overly loose and fairly aggressive (that is, more aggressive than me, AND playing more hands). I suspect he is new to razz, have never seen him before today.

I don't love my hand on 3rd but I want to isolate and the guy showing a 2 is tight and will only call me with a hand.

on 5th I know he's ahead right now but I think I'm a 60:40 favorite even if he has 2 cards under 8 in the hole. Worst case is he has A2 and I'm a 60:40 dog. Anyway I think he's just betting because he caught a 9 and I obviously have J high.

On 6th there is no had he can have that beats me, just ties, so I'm willing to put in a lot of bets here.

On 7th, what do I do here? After action on 5th and 6th I was surprised he'd bet into me. His actions on 6th make me think he had a pretty sweet draw. I don't think folding is an option, but what about raising? If he re-raises I do what?

Razz ($0.50/$1), Ante $0.10, Bring-In $0.15 (converter)
