big draw in position

opp: regular tagg 22/18, AF 4.6

obv on the flop if he ships I'm getting it in which I would generally expect from perhaps AA/KK/QQ here. Now he just calls so I know he doesn't have a big FD or a set. When he checks do I always want to bet the turn hard. Being in position I opted to get the free card because I knew due to his huge aggression he could likely CR shove me with a medium pair or a hand like he actually had in which case I'm then forced to commit due to pot odds.

What's your best line, and if you do take the free card and he checks the river do you shove or bet it and how much?

thanks very much

Bet turn. He never has better than one pair, and most likely doesn't have AA-JJ. You have a crapload of outs.

how much do you bet so he doesn't think you're on a draw? 2/3, 3/4 ?
