Strange Nut Flush Hand Against TP

[shpanko]

Villain is 19/12/1.5, Hero has been running like 25/20/3 and pretty active at the table, c/r'ing flops 3-betting pf a lot. I haven't really been caught bluffing that bad asides from a few c-bets that got called. The flop c/r I feel is fairly standard b/c his calling range is fairly narrow on the A high flop. Then his raise is so small that I feel committed to call.

Once we hit on the turn what's our plan? Bet? If so how much?

Hero?

Note stacks are ~180 BB's. PF isn't standard for me but the BB was real fishy and MP and I are deep so I don't think it's terrible. Especially since I'll be making a lot of moves on the flop.
