Razz: Jammed on Third Street

[AlanBostick]

So I've got a seven in the door and A6 below. The other low cards out are a 6, who raises the bringin and an ace acting after me. I call the raise, and the ace reraises, the six three-bets.

I first thought that most of cards that help me are live, but evidently four good ones are gone.

Do I call the two extra bets, or do I fold here?
