NL$50: Bet or stack a donk?

[Chargers In 07]

Open raiser is 16/3/2 after 35 hands, so no real read. I've been opening lots of pots and have an aggressive image. A couple hands ago he floated me on a Kxx flop w/22 and I check/call turn w/JJ and river goes check/check.

Hero checks or bets?

$14. Too many draws and its good for your image to just keep firing anyways. You'll start getting looked up lightly.

Hero bets $16.20.

I bet. He can be calling you with a variety of draws/made hands if your image is overly agg. I think you have to play off that and bet. I like the $14 idea.
