Villain in this $20-180 is aggressive post-flop and has called many steal attempts pre-flop. Ok line?

If he has been calling lots of preflop raises, how is he reacting to c-bets?

I am likely c-betting this flop. If you would make a c-bet here if you missed the flop, then you should definetly make the c-bet when you connect. The flop bet has two purposes as you are likely to take down the pot with the bet and your hand also has some showdown value. If he calls my flop bet, I try to get this to showdown as cheaply as possible.

Bet the flop. He'll fold a lot in this spot, or he may be calling with the worst hand. As played, I'd fold on the river because you aren't really ahead of much.
