Too loose, or pictureperfect?

Picture this:

BB is a true fish (loose-passive and very very weak), UTG has a VPIP of about 70-75, Button is a TAG.

You get A2o in the CO, UTG calls as ever, everybode else folds to you.

You like A2o enough to think its good enough for this very specific situation to raise with?

nope... If you can get them to fold on the flop easily then yes, otherwise no...

I auto-raise this to clean up the button and most likely your ace outs. Depending on how UTG plays post-flop, this is an easy read whether you're wa/wb.

No probably not. BB is going to be in the hand regardless if he is extremely loose. SB might be in there too. You'll probably have to play the A weakly if you hit and see any resistance. The 2 is nearly useless if you hit it and there are a couple of people who will call down with anything in the pot. So I definitely do not raise in this situation.

I'd wait for a better spot, you have little equity with this hand as the fish described will likely play any ace for 2 bets.
