Your effective pot odds, assuming you call the turn raise and another bet on the river:

(6.75 + 1) : 2 = 3.9 : 1

so your hand has to be good more than 1/(3.9 + 1) = 0.21 = 21% of the time to profit from calling down. Against the majority of 2-4 players I doubt you will win as often as that.

Unless I had reads and strong reasons to believe Villain was making a move, I would fold.
