NL2 SH, AKo vs BB squeeze

I don't think he will be that tight at this spot. There are so much dead money in the pot to collect with an iso raise. The amount is also small... I would 4bet.

If I 4bet, I would isolate myself vs better hands (sure, some times he will fold). I don`t think there is enough 'dead' money to justify this play.
If you think he is not that tight, should not I be better of by just flatting IP?

You want to invite the players behind you to stay?

I rather invite them with weaker range, they would play fit/fold anyway.
For me, it sounds better than risking my whole stack vs UTG squeezer.

In the micro's folding is fine here I believe. 4betting can never be very profitable. You'll make him fold some of his bluffs sometimes, but you'll also be obliged to go broke as an underdog a lot of the time. Considering the rake, 4betting doesn't seem very profitable to me, unless squeezer's stat look somewhat loose. Not saying 4betting is a -ev thing here to do, but it's a close one. Think I would keep down variance here and move on to the next one.
