$1000 eff, 3-handed. I raise button with AdAh to $40, BB calls. BB is a hardcore reg, does some stupid stuff with good frequency but definitely not a donkey. Can play tight but has frequent LAG outbursts. Loves to 3b wide and light preflop. Loves to raise flop. He's capable of raising flop with draws, bottom pair+gutshot, top pair and of course monsters. Most of his flop raise range is draws. Generally after raising the draw and getting called and missing, he will check the turn. He's also capable of checking turn if he hit. He won't bluff river.

Flop: 7d2h9d Pot $85. BB checks, I bet $60, he CRs to $180.

I have a very strong read that he's on a draw. Given that and my read that he checks whiffed turns - what's the best line to extract value from him?
