a little value on crappy boards?

Hand 1:
-villain is playing pretty taggy overall, but haven't had many hands on him. He hasn't done anything that stood out yet and is running 22/17 over a small sample (100 hands)
-he probably doesn't have any impression of me yet
-is this turn always a bet? if so how much?

Hand 2
-villain is new to the table, so no reads yet. I'm not sure what his range is
for leading into me on flop and calling my raise
-after two checks, does this river have any more value?

Hand 1 I see value in betting, 200 or so.

I think hand 2 is actually more of a good bluffing spot than it is a valuebet.

Hand 1: Wow, this is super tough. I think I lean towards check behind since we have pot behind and can easily get a stack on the river. His hand kind of looks like AK, QQ, or KQ too so it seems like i'd rather wait and see..
1. the river card
2. if he bets into me on the river.

If he checks i shove it like its hot.

Hand 2: Yeah just check.
