deep stacked

We don’t know how big that 3bet is, but in the vast majority of instances I think the answer is yes.

This is right ^^ that is extremely deep stack, and I think regardless of position, unless the 3B is enormous - I'm seeing a flop with 89s unless it's like a quarter of my stack to call.

What do you believe the chances are the original raise will 4bet? How big is the 3bet? How good are the Vs in the hand? Anyone else other than the raise and 3 bet call the raise or 3bet?

I am calling a reasonably sized three-bet from the BTN if I was the opener and the three-bettor is one of the blinds.

It would take a lot for me to even consider flat-calling a three-bet on the button with just about anything. Biggest consideration is if there is a fish I want to keep in the hand.
