1/3NL: A high in RR pot OOP

[overun]

1/3NL live game. My stack is about 500. Image is probably somewhat loose, but most of the players at the table aren't good enough to play back w/out good cards.

Villain in hand is very loose preflop, but somewhat more predictable postflop. He's normally a calling station, and rarely fires out without the goods. He loves calling with all sorts of draws, either OESDs, FDs, pair+gutshots (sometimes without good implied odds: ex. in another game, he raised in the CO, I reraised OTB w/ AQo, he calls. Flop comes out 7 high, he checks, i bet out 3/4 pot, he calls, turn is a blank, i bet 1/2 pot, he calls again, river goes check, check. He had an OESD on flop and hit a pair on the river to win the pot.) as well as strong made hands HU, but sometimes will bet/raise with combo draws or when he has a made hand and draws are out.

I'm in the SB w/ AJo. There is a straddle to $6, and Villain restraddles to $9. Three more people call the restraddle, I pop it up to $50 to go. Villain thinks about it for a second and calls, everyone else folds. Effective stacks are about $240 after the raise.

Flop comes out 842r. What's the best plan of action here? His cold calling range preflop is very, very wide, although generally it's more towards connectors, gappers, and small/mid PPs.

If I bet and get raised, most likely I'm folding. If I bet and get called, should I shut down on any non paint turn? If I check, and he bets, should I c/r or c/f?
