I have some questions in some spots

We on UTG open near 15% and have pretty standart fold to 3bet  50-60, OR AJo

MP or CO make call pretty tight 8-12% (22+,AQo+,ATs+, 87s+, J9s+) 

And Flop comes Kh 7c 2s

on such board he calls tp+, srp and bckdr fd - QJs, 98s, ATs+ (maybe QTs, JTs)

We have only 34% FE

and even turn comes T - we don`t have enough fold equity, and only on the Q we have near 40% with our gutshot.

It`s easy ch/fold spot? And with what hands, which missed flop, we must bet? All broadway that has bckdr fds+oesd?
