Hi all...shall we go 4-bet all-in with this with ca 19bb? Made a calculation and it could be slightly +EV (+2bb EV ca) versus 3betting range of villain like this: 99+, AQs+, A4s-A2s, Ad5d, Ah5h, AJo+, presuming he would fold 99,AJo and A2s-A5s (or whatever bluffs may he have there) and we would have ca 37% equity when he calls with given range.

I guess it's fold tho as players on micros will probably be tighter here with 3bet vs UTG.

What range can we 4bet shove here as default in this scenario ? I'm so bad in these spots with shortstack...

I think we need like 40% equity here if called to be good in this spot and by my calculation we should 4bet all in TT+ and AQ+ considering his range will be pretty tight here...right?

The best way may even be folding 55 pre with 20bb :-D
