2-5 NL live hand vs a weird lag

I haven't posted a hand in a long time so here's a hand that I played awhile ago at a casino. I brought 1K with me and bought in for all of it, but I only have $500 left because I took one bad beat and played another hand bad.

reads - button is a nit, and SB is a loose passive old guy who is on tilt. BB is a LAG who plays anything remotely suited or connected. A few hands ago he raised pre-flop with 94s and called a re-raise. He called a bet on a 678 flop, turn was a ten and he made small bets on the turn and the river and won a big pot against JJ. He's in his 20's with slicked back hair, a hoodie and Oakley sunglasses. This casino is near Silicon Valley so my guess is he recently got a job there and now he thinks he's awesome. He's probably smart and knows that I have a tight image, but I think he cares more showing off than making money. He hasn't been at the table for very long but I'm starting to think the world would be a better place if someone killed him with a Mortal Kombat fatality.

Folded to me on the CO and I make it 20 with KTo. Button folds, old guy calls, young guy calls too.

Flop is 67T rainbow and the douchebag donks into me for $60. I haven't seen him make a bet like that before so I decide to call and see what happens. The old guy folds and the turn is 5 putting two hearts on the board (I don't have a heart). Young guy bets $60 again, do you shove, make a small raise, or just call?

I think that I fold the flop vs this villain

As played I guess you just get to call turn and call river and pay off 89?

I don't understand. The guy's range is this big *stretches arms out really wide* and I should put him on the nuts because he bets the flop? He's been playing really aggro.

Well the only hand you saw him showdown he had a pretty decent draw.

If you really think his range is monsters, air and worse 10's (or some random shit like A9) then raising serves no purpose (unless he'll call a raise with a gutshot) so just call turn and call pretty much any reasonable river bet.

I still dunno if it's that big of a deal laying down K10 on this board when he leads into 2 oppnents on this flop unless you've seen him make strong bluffs in multi-way pots.

i like the flop call. waiting for a monster at a live game is gonna be uberboring and bad for ur image, and i bet the BB tends to not pot the flop with a monster, or at least has a real wide range to do it.

im thinking raising small on the turn is the best play.
he just doesn't sound overly tricky-aggro...more like aggro in small pots. missing value sucks if he'd smooth call a turn raise with a draw, and checks the river if missing.

This is never a hand beating you, so yeah i like a small raise.

You mentioned he plays a lot of hands but do you have any reads on him leading into PFRsers?
