1. I open raise with AJ from any position. I might fold AJ in early position if facing a raise (depends on situation, of course...) -- but with no raise in front, I raise myself.

2. I never enter a pot and fold to a raise when it's only one more bet. I can't think of a situation where you would do this with any hand you considered entering the pot with in the first place (except for maybe if the limp was a mis-click in the first place). I probably fold, though, if it's raised and re-raised.

Here,
- A) you're getting great odds to call here (even if you're dominated).
- B) rock may even be raising with hands that do not dominate you or may even be worse than what you hold (e.g., KQs, ATs, TT, 99, etc.) to buy button, drive out the blinds, etc.
