Slightly lost with oesd in 3-bet pot

[HustlerLA]

So when 3betting a villain who has a tight 3bet calling OOP range, is it best to give up on the flop if we miss flop? Seems -EV to make this move just to take it down pre and give up on a missed flop which is most flops.

this pot is more difficult to play because we actaully got a nice flop and dont want to be pushed off.

What is the consenus if the flop was 2 4 8 r,? Is making a bet on that flop best becasue our only hope is FE and if villain shoves we have an easy fold? Or do we just c/f?
