So this spot has happened to me a few times and I was always curious what to do. Villain opens and I 3bet him IP on BU, mostly we were 150-250bb deep. I have AAxx. The flop comes something like K94r, I cbet and he x/calls. Turn brings something like 7 or 8 and giving me BD nut flush draw. Now the SPR is around 3-4. And here I'm ussually wondering what to do. A lot of villains are slowplaying KK or K9 in this spot to x/jam turn. But on the other hand, villain can still have a lot of KQJx, QJT9,... So what I'm asking is, do I bet turn or check back, realizing my equity. I guess it matters from which position villain is opening and how loose he is playing.
