Situation 1) Just looking for your default play here assuming you have no reads. It is folded to hijack who limps, you are next with Ah4h... What is your play?

Situation 2) No read on Hijack but the players behind you are all loose and tend to coldcall raises loosely. Hijack limps, you are next with Ah4h....What is your play?

Situation 3) This time the players behind you are all tight. Hijack limps, what is your play with Ah4h?

Situation 4) Tight passive limps UTG in a 9 handed game, it is folded to you on the button. SB is tight, BB is loose, you have Ah4h....What is your play?
