Q6s vs weak fish

Villain is 50/40ish lag on rock infested table. Took me a short time to realize he was the prime target. Saw him minraise weak twopair vs river bet and snapcall 3bet for like 3x on wet board (the other guy had flush). Also bets flops big, and turns small if he is weak, easy to take down by a raise.

Here I called because it was cheap and its wrong not to be in a pot with this guy. I don't see him having anything on flop, prolly just betting big to scare off both of us. Hows my raise size? 4x maybe better?
What to do on turn? Jam?

Another hand, still the same fish. No relevant info on other villain. Whats the best line here and why? Obviously I'm trying to extract some extra value from other villain but I fear calling will seem way too strong.
