3 handed 5-10 little deep

[gomberg]

3 handed 5/10. I'm on button ($2.2k).

I raise to $35 w/ 85o. SB folds, BB calls ($1.5k)

flop ($75). 258r.

reads:
Player in the BB is why I'm playing. He's been calling a lot of bets w/ very random, non-strong hands postflop. He had just seen me bet 1/2 pot on two streets w/ a monster then full pot river. His min-raises mean at least a pair. He's also never reraised preflop - he's cold called out of position twice now w/ AA and KK then ended up potting the turn and river w/ an overpair.

Back to the hand...

BB checks, I bet $75, BB CR to $150, Hero...

Plan for rest of hand?
