Ok, so you never fold them. Fine. Are you always raising with them? I'd say I do 99% of the time if I'm original raiser, and probably reraise 75% of the time.

I am a decent post flop player, and can usually fish out when I'm beat, so I'm comfortable limping and folding if I have to, but I subscribe to the theory of betting your quality hands when you get them more often than not.

I have probably only laid down KK successfully once or twice that I can think of and it was never heads up. I currently subscribe to the same belief... I'm never folding KK preflop. My doubt has been in seeing them get outflopped for more than half my stack or all of it on many recent occasions when it's all or nothing preflop.

Also, why did you use 100bb as a measuring stick?
