Preflop, I agree with the other players, your 3-bet should be somewhat larger 5x or 30c seems about right.
As this is MW, on the flop I would x/c this most of the time as you have a BDFD but it is dependent the opponents. To protect hands like this, I will also x/c hands like AcQd on this spot so that people that play regularly against me are not so prone to bluffing
I would then only continue if I improve to a FD or TPDK with x/c on the turn
