25NL Defending vs btn steal

Villain 12/7/inf, with 29 ATS, multitabling reg.

Pre - I flat since his open range is huge, 3b probably not good, yada yada
Flop - He's betting entire range here, and I guess a raise here would be good, but I think if I had say a mid pp or Qx I'd also flat this flop
Turn - Here's what I'm thinking.. if I bet here, he's going to define his hand. He'll flat with all his pairs, and fold out all the junk. I guess I'm still crushing his non-pair range, but I wouldn't be comfortable checking here and facing a bet, or have him check back and c/f the river. My plan going into the hand was calling most cbets on dry flops and leading the turn.

Thoughts?

is our plan to c/r the turn or like just flat him a second time and try to show ace high down?
