We do get one read very quickly. This guy is a fish. We find this out on the flop when he donks 6c oop into a raised pot.

Raise flop more. You're betting 14c into a 36c pot on a draw heavy board, it's far too small. Something like 28c is what I'd be raising to.
Turn is fine, call river. He can certainly have us beat here, but he can also do this with Qxdd, and other pairs he's overplaying. I am definitely not folding, while raising would be overplaying our hand. Flop raise is fine other than sizing, but after he donks turn we're right to just pick off his bets.
