200nl- Extracting value

[mxrider]

Couple of notes: Button steals a lot (44) and only folds to 3bets 56% and flats cbets 67%. I'd like comments on betsizing preflop and on the flop. On the turn, what should my action be???? When he calls the flop cbet, he has a 0% fold to turn bet (only twice) and once he shoved over me when I double barrelled a flushdraw and had to fold.

I think, bet sizing is fine.
Just bet on the turn. It's not a good situation for him to bluff and he might think, that we are double barreling and shove a flushdraw - or he might have an A and can't fold it...
Betsizing is dependent on your style.

Shove the turn. Bet a little more on the flop so that the turn shove isn't so close to pot-size.
