Preflop: good

Flop: good (a c-bet can be discussed of course)

Turn: If BB is a thinking player you have a tough decision now, cause he should know that AK is in your range. As he fires a psb against two opponents indicates a strong hand for me, and there are a lot of possible holdings in his range that beat you (KT,33,99,TT,QJ,AA).

So you are in a tough situation now:

- you can push the turn as you did
- you can call and fold if he pushes the river
- calling turn and call a river push is bad (pushing the turn yourself is better)
- you can fold

so none of these choices look really good, but as this is a 5$ buy-in I think pushing the turn is the best one. at a higher buy-in I would even think about a fold here.
