Hi all, let me get this straight, SB only had enough chips to post ante and Small Blind, so he is auto-allin.
This means he is dead money and was not even dealt cards right? Or is forced to fold his cards or something?
He is out anyway and we are in the money right?

PokerStars - 80/160 Ante 20 NL - Holdem - 4 players
Hand converted by PokerTracker 4

SB: 80 (VPIP: 27.12, PFR: 7.14, 3Bet Preflop: 3.57, Hands: 59)
BB: 2,176 (VPIP: 51.52, PFR: 9.09, 3Bet Preflop: 0.00, Hands: 34)
Hero (CO): 3,113
BTN: 8,131 (VPIP: 41.67, PFR: 31.43, 3Bet Preflop: 0.00, Hands: 36)

4 players post ante of 20, SB posts SB 60, BB posts BB 160

Pre Flop: (pot: 300) Hero has T T

Hero raises to 320, BTN raises to 8,111 and is all-in, fold, Hero ...

No. Unless he is sitting out, he needs to be beaten. He will be all-in for 240 chips vs BTN.

If you also call, SB needs to win vs both of you. If SB beats you, but BTN beats SB you get 3rd place.

the thing is, I called and his hand was auto folded, here is the full history:

Raw history, looks like they forced him to sit out or something, he did not participate in a final showdown despite being allin:

If he is sitting-out the hand gets auto-folded. But only if he is sitting out.
