A8o with a shortish stack

[Autocratic]

Tiny $1 buy in tournament, I just started with MTTs, so the money factor isn't really relevant here. 16 players left out of an initial 350 or so. Average stack is about 30K, I'm down to 17K, blinds 800/1600 with no ante. I'm dealt A8o in the CO, and the action is folded to me. The button is almost entirely irrelevant, as he clearly wants to limp to the final table. He has folded everything so far. The SB has 5K chips left and has also been playing weak/tight. The BB has about 24K and has been playing a pretty solid game, from what I can tell. Not unwilling to gamble a little, but certainly not reckless.

Do I push here, or let it go and wait for a better chance?
