Hi everyone, recently I have some problems with the volatile player profiles. Just basically dont know how much credit should I get him.
First question: can we make a 3bet OTF and stack off with Jx and straight draws?
Second question: Should we make a fold on the later streets?
My reasons for calling down were like I have a good nut blockers, I am beating Jx hands and his turn and river sizing is half pot (see more bluffs with this monotone sizing, especially vs a fish) and OTR missed some potentially flush draws. And also dont see that many Kx hands which he is raising on the flop.

V is 39/32 after 32 hands
