100NL (20bb-200bb buyin)
Villain is unknown but over small sample seems like a solid tag. No huds available.
My main question is what should we be calling with in this spot also what hands would you 4 bet?

LJ ($32) limps $1
HJ Hero ($172) AsJs $3.50
Co fold
Btn folds
Sb ($230) 3 bet $14.50
BB fold
LJ folds
Hero ?

Typically continue range would be:
A10s+, KJs+, 77+, AK+, T9s+

SB 3 bet range
TT+, AQ+, A10s+, KJs+, QJs+

Postflop a lot of players on this app just smash 50%, 66%, 100% pot buttons on the flop, so not a lot of floating we can do postflop vs a 1\3 sizing you see in training videos.
