Wow. So it's a 1/2 game, its raised to 10bb, and there are 5 callers? What kind of crazy game do you play in.

That being said, I fold preflop. But as it was played, I'm not a fan of the push. Given his raise, and his bet, there's really nothing indicating that your AJ might be good.

His call is questionable, but IMO, so is your push. (unless you have some reads on the guy)
