$10 NLHE 6-max: TPTK on scary board vs loosing reg!

Hey, so villain is a loosing reg so far, playing 21/16/2, tries to steal from button every single time, folds to 3bet about 50%, 3bets 13%, goes to showdown 41%, wins at showdown only 50%, folds to flop cbet 0 out of 5 times so far, and I have 150 hands, also I have a note on this guys and it says "calls 3bets with small pp out of pos""

Ok so turn get scary, and I have TPTK and about 1 pot size bet left, do I shove or do I check behind and hope for a showdown?

Hm.
So it seems villain has aggressive tendencies pre, but plays mostly abc post?
I think I'm betting 2.20 again and folding to a raise. If he calls the rest can go in on the river (unless it's a spade).

i want to say shove but I don't know what calls us with worse other than KQ. I'm thinking I would check back here and probably call a river bet or if he checks i'd throw out a small vbet

I would keep betting until he bites back ... then fold I would have thought hands like 1010, j10, kq. qj,Aj, K10 and gutshot pair combos might call

Shove, and 3-bet larger.
