You are good vs a typical LAG's range here and dead in the water vs a typical nut peddler. With no read, I like to give my opponents credit for the latter until proven otherwise, as they tend to prove the otherwise rather quickly. If you feel you are more likely to be ahead and are going to continue with the hand, just put 'em in on the flop,as there are a LOT of cards you will be playing guessing games with on the turn.
