Fundamentals of 5-card stud, how to play small starting pairs?

[BlueBear]

Crossposted to the Stud forum. I post this stud-related question in the poker theory forum as I feel that question is very theory based.

Assume that I start with a small pocket pair, say 33 to 55. In this game (full table 5-card stud), the low card opens, and the player directly on my right opens with a 2.

How should I play my 33? How does the ante-structure dictate my choice of play here? (I am assuming in a game with no ante, the correct play is fold).

Also, how I should I play them in a no-limit structured 5-card game?
