Hey,

yesterday i got into this spot and i really have no idea what to do. Is folding okay? Or should I 3-bet small or 3-Bet shove? I have no idea what a range the SB is playing there. Calling is no option in my opinion.

PokerStars - 60/120 Ante 15 NL - Holdem - 9 players
Hand converted by PokerTracker 4

UTG+1: 7.47 BB (VPIP: 50.00, PFR: 2.78, 3Bet Preflop: 0.00, Hands: 36)
MP: 20.4 BB (VPIP: 36.67, PFR: 0.00, 3Bet Preflop: 0.00, Hands: 30)
MP+1: 35.98 BB (VPIP: 31.58, PFR: 5.26, 3Bet Preflop: 0.00, Hands: 19)
MP+2: 10.72 BB (VPIP: 36.11, PFR: 30.56, 3Bet Preflop: 16.67, Hands: 36)
CO: 24.2 BB (VPIP: 50.00, PFR: 0.00, 3Bet Preflop: 0.00, Hands: 4)
BTN: 10.18 BB (VPIP: 21.05, PFR: 10.53, 3Bet Preflop: 0.00, Hands: 19)
SB: 24.23 BB (VPIP: 33.33, PFR: 13.89, 3Bet Preflop: 0.00, Hands: 36)
Hero (BB): 22.42 BB
UTG: 16.43 BB (VPIP: 13.73, PFR: 8.00, 3Bet Preflop: 4.76, Hands: 51)

9 players post ante of 0.13 BB, SB posts SB 0.5 BB, Hero posts BB 1 BB

Pre Flop: (pot: 2.63 BB) Hero has 8 A

fold, UTG+1 calls 1 BB, fold, fold, fold, fold, fold, SB raises to 2 BB, fold, UTG+1 calls 1 BB

hard to say how their ranges look like in 0.25 sng tbh. i would treat this as if sb min raises blind v blind, so defending is good here

Why is calling 1 extra BB with 20 behind no option?

You have a small sample but enough to know that SB's stats are not those of a good player - a player whose 'passive gap' (i.e. VPIP-PFR) really is 20% is 30x more likely to post that stat over a 30 hand sample than someone whose passive gap is 6%. Yes he could be trapping but he could be doing a lot of other things and no we don't know his range that well.

I'd be happy enough to call a couple of streets with a flopped A or pick it up if no one else wants it postflop so 1BB is worth paying to see a flop with 7BB in it.
