You snuck your reads in on me, however, I'm not going to alter my post.

First, would need is a read on your opponent however without it we can still come to a decision.

What I like to do in these situations is try to build a hand range for my opponent and use a tool like pokerstove to determine my equity against that range. I then take my equity, compare it to my pot odds, and make a decision.

Let's say that our opponent will certainly do this with AA and KK, he will also do this 33% of the time he is dealt JJ, QQ, and AK. Also, every once in a while he's the world worst poker player (quite possible at 2nl) and once in every blue moon he has AQo. Make sure you realize the is definitely the tighest (best) hand-range this player should ever have. If it were me at the time I would go all-in over his shove to charge the player on the button the maximum in this spot.

Let's look at a very tight range:

Board:
Dead:

equity win tie pots won pots tied
Hand 0: 40.198% 28.03% 12.17% 7198143 3126434.00 { AhKh }
Hand 1: 59.802% 47.63% 12.17% 12233549 3126434.00 { KK+, QcQd, QdQh, JcJd, JdJh, AcKc, AdKd, AsKs, AcKs, AdKs, AdKc, AsKh, AsQh }
Now let's look at a much looser range:

Board:
Dead:

equity win tie pots won pots tied
Hand 0: 52.067% 44.68% 07.39% 45899511 7593030.00 { AhKh }
Hand 1: 47.933% 40.54% 07.39% 41652669 7593030.00 { TT+, 44-33, AJs+, AQo+ }
You can see how drastically our ranges change if we perceive this villain to be capable of this move with a larger/weaker hand range. We've now gone from a 59:41 underdog to a 52:48 favorite, making this call PF fairly easy/standard. I would have made this call, and if I were playing $2nl I'd have a bankroll in the $75-$100 range and not have to worry about gambling it up with the donkish players who make moves like this. Make sure you're always rolled for your level and these calls become much easier to make.
