Just happened again. First round of an SNG tourney so no reads on anyone, but no reads on me either.
Dealt AK. Raised 8x BB preflop. Two callers. Flop comes K A 6 rainbow. I make pot sized bet. One caller. Turn is a 4. Pushed. Guy calls my all in and turns over pocket sixes.
Unreal. I'm totally scared of AK now.
