SB tight reg

Preflop

std

SB tight reg but don't know why he opr tons bvb vs me
3bet standard here with AAxx ss

Flop

Good flop.
Top set, disconnected flop (not affraid of wheel wraps here), but this FD heart.
Don't want to bet too loud. Give him prices to call at least one street with Axxx, and hit DP later.

Turn

Still nutty on this board, but it's turning quite drawy now.
I need value/protection, and SPR is turning quite low (SPR ~2)

Just pot it ? With the SPR and the drawiness of the board, it doesn't seem me a mistake.

In an other way, I'm never bluffing here when I pot, and on this spot maybe I need a range of bluff (I'm ip, I can try to rep AAxx if I have some 5678-like that missed, and I have some FE turn and place to put the 3rd barrel bluff river if needed)

And how would you play turn with a medium hand (like bare DP A4xx or A9xx) ? line, sizing ?
And with a good straight draw ? wrap ? pot it too
