I think the push after the check and flat call preflop was definately the right move with your hand.

Playing the hand in the first place is what I am more interested in. I have had a lot of situations like this recently where I am not sure if I should fold or raise. I lean towards folding because they have seen you steal recently, 4 to act 3 of which make things very hard on you if they come over the top, and stealing doesn't greatly increase your relative position with the stacks the way they are. Curious on this since this has been my big dilema recently with these sort of hands close to or at bubble.
