Villain's 58/21/1 over about 65 and from what I had seen is a monster station/bleeder - called a flop raise and two barrels with middle pair on a 4 flush board 20 hands before this.

So, the call preflop i obviously a bit loose but I was trying to get in some pots with the donk. However, on that turn...what's my play there? I feel like he's the kind of player who raises AI with a lone 9 there, and it's clearly not the best card for me to bluff, and I think he's still calling with any pair, which puts me in a really awkward position when I don't hit on the river. A friend of mine suggested just calling the flop bet, but I don't know how I feel about that, even though it may have kept the BB in the pot....any advice will be greatly appreciated, besides 'don't call raies oop w/ A7s'...thx

IMO fold in SB. As played, bet the flop and check it down to the river. Fold to the re-raise on the flop or raises on the turn and river. Your playing this OOP so this is rough. He is going to be in almost any hand you play so better to wait for the right cards.
