c/r on the flop, if button 3-bets, call and c/f the turn UI. Otherwise lead the turn, call if raised, and c/c the river if its HU, otherwise I would c/f if SB is still around.

I encourage c/r the flop to gauge your opponents strength, if they 3-bet you and you improve on the turn, you are likely to extract a few more bets from them. c/r may also force overcard draws to fold on the turn.
