Hello dudiloiu,
Actually I'd say that thin value is often times even a leak and which may cost you a lot in long run. And therefore you really have to search for those kind of spots.
Now lets take a look at the hand. We are against a station who goes to showdown a lot. Therefore we can consider taking big value here and by what I mean I would usually bet with made hands pretty big.
Flop: Would bet it like $1,20+ for value from any kind of Ax/draws/maybe even weaker PPs.
Turn: Would as well bet it bigger ~$3 at least and if we get raised then we know where we stand since he is pretty passive player.
River: And yes, I would likely go for value here. If he had like flush I am pretty sure he would be inclined to raise it on turn or at least donk the river to not miss value. Therefore I would go for value on river and maybe even if I would have done those bigger bets on all streets we could easily just ship it here. Expect to see a lot of Ax holdings in this case.
Best regards.
