What bet to make in this Texas Holdem Tournament?
You had 8 big blinds. That is a spot to push pre flop (go all-in) out of position (OOP). You should be playing a wide range in that spot and could get called with a wide range. You win the bet that was placed and the small blind if the villain folds. Losing to K3 is unlucky but you need to gamble with a small stack and AA is a good hand to gamble with.
