Pretty live table, lots of guys are drinking. This is all I know, I just sat down and this is literally my first hand at the table and I get A♥ A♦ in CO and I have $500.

Someone raises UTG+1 to $15, 2 calls, I 3b to $50 (too small?) in CO, button cold calls 3b and everyone else flats.

Flop: 9TJr Pot $157 Checked to me....... (only button behind me)

Is there merit to checking back and why? What should be our plan for the rest of the hand? Remember this is my first hand at the table and I just sat down and the only read I have is that this game is a bit wild.
