Squeeze spot or Fold?

Should we 4bet fold or 4bet call?

1. Your size is very sub optimal. You basically committed yourself into calling. When you make it 2.50, you need to call 3.85 more to win 13, pot odds = 29.6%

Equity Win Tie
MP2 28.60% 27.30% 1.31% { AQs }
MP3 71.40% 70.09% 1.31% { QQ+, AKs, AKo }

Even against this ultra strong range, you have almost enough equity to call. So based on your 4bet size, you are committed and have to call.

You should make your 4bet size 1.80-2$.

SB is short, ranges are wider for 3betting. I think AQs is a call.

Equity Win Tie
MP2 39.83% 32.17% 7.66% { AQs }
MP3 60.17% 52.51% 7.66% { 88+, AQs+, AQo+ }

Villain is probably jamming 99+, AQ+, maybe even 88. Your pot odds if you make it $2 preflop is ~33% which makes it a pretty clear call.

And this is a clear 4bet, assuming the average guy at microstakes is 3betting 10%+ of hands here in SB vs BU.

Thanks a lot.
