I think this was a 56$ game on Bodog. Might have been a 29.

SB: 2300 chips
BB (Hero): 2000
UTG: 4200
MP: 2000
CO: 1500
BTN: 3000

Blinds 200/400

Hero dealt AJ

Fold,Fold,CO raises 1500 All-in,Fold,SB calls 1500, Hero?

Yeah so do I call this or not? Both of these guys are regs, and the only fish left at the table is UTG who doubled off me earlier by calling with T8s on the bubble when he was 3rd in chips. I think this info is somewhat relevant because if the game continues I have to steal through this guy.

I have at least 100 games of history with both of the guys involved in this hand and I'm very confident that CO is shipping any Ax,Kx,pair, all Broadway combos and maybe some suited Qx,Jx and high suited connecters. I also know that SB is never calling light. He has TT+ AQs+,AK and he may even be tighter than that. I wouldn't be surprised if he was calling QQ+,AKs.

If I call and CO wins I'm very short, ~1.5bb, but there's a good chance that if I do call SB has a pair that dominates CO and I have an ace that also dominates him.

Folding means that if the shortie doubles SB is left with about 2bb.

Is this worth a call? What's the bottom of my calling range?

snapfolding this....really don't want to be flipping (at best) here when there will either be a megashorty or we're ITM next hand.

I'd want KK+ to call here personally.

fold, i might call AA (push) depending on my mood, when 2 players are allin there is no reason for you to get involved, unless you are playing in a team with SB, then sure- call with any two cards
