This hand has been driving me batty for weeks so let's see what you guys think.
In a tourney, blinds 200/400. I'm in the BB. Healthy stack.
Guy under the gun raises to 1200. He's been pretty quiet for over an hour I've been playing with him - maybe played 3 hands tops.
I look down at K ♣ K ♠ so I re-raise to 2600.
UTG 4-bets to 5k. Hijack folds.
I make the decision to find out if he has AA and pop it again to 12k (still have 23k back). He then goes all-in.
So here I am in a 6-bet situation for the rest of my stack against a complete nit. I still had plenty of chips back. I'll save what I did until I hear what everyone says but do you call or fold?
