I think it depends on villains image of you. Assuming he has not seen you bluffing it is a check for me and call a small bet. Id put villains likely range to be JJ, TT,99 and 88. KK,QQ he 3 bets pre. Any sets / straights I think he"s raising turn. You are probably ahead so you need to call a reasonable bet, but I dont think he"d call a third bet with anything you beat. If however you have been loose and agressive then a $4 bet will prob get a crying call from JJ,TT,99 .
