first, if i was not a blind and blinds were not big, i would've folded this preflop. but there is a 2/3 chance you were in a blind and blinds may have been decent so i'll give you the benefit of the doubt.

yes, fold the turn. you'd be calling away more or less your whole stack and sacrificing your chip lead for a less than 20% chance of winning it all right there. Let this play out between those two and risk it all when you're a favorite, or at least not so far behind.
