Preflop: AA. I’m always positive about getting it all in pre with aces, when i look at aces and someone shoves I feel like I have a super power ready to be unleashed. Post flop play, I think I actually like KK better. If you flop a set with KK you can still be against an opponent who believes they have the best hand, whereas if you flop a set with AA it’s hard to get action from weaker hands since there’s an ace on the board. Also, I have no problems folding KK post flop if it looks sticky, but AA can be a death sentence.
