Okay, I've played with villian for around 50 hands. He's running at 18/4. He's been playing so tight it's not funny. he's limp folding hands on flop/river a lot.

I get priced in with Q10 in the BB against some nice deep stacks.

I've noticed that the player that raised preflop is folding a lot if bet at after flop, so I wasn't worried there.

I was moreso waiting to isolate the tight villian.

What would you expect is a big enough bet to take him off a small pp or very weak K on the river?
