[Tailgunner]

I wouldn't have opened with it PF, limping and considering the action if I need to call a raise... I think it's too marginal out of position to risk an open-raise approaching the bubble when you consider it likely that at least one aggressive player will call and you don't know if the blinds may have hit a hand. The last place you want to be is tested for all your chips by a blind reraise when it probably won't eliminate the villain.

Having been card dead should never be a consideration.

If I was fishing for information with that 1/2 pot bet, yes I would have stuck to my guns and folded to the check-raise. Knowing he's super-aggressive, however, I would not expect that bet to reveal anything and would have pushed the flop to break his drawing odds. I may try to check it down if I truly feared AJ or J9, but not with the read you had.
