I say call. Pot odds are 2-1 and you're probably not a far worse dog if behind. Also image considerations lead me to favor a call: if u back off here, the chances are other players will target you for future moves. The call sends the message: don't F with me, or be prepared toe die. Losing the hand is also not a disaster chip-wise. It's not as clearcut as quizhand #1, but im pretty sure the call is the way to go.
