If I'm going to steal the blinds, any hand will do, at least from the button. I will make this move from the SB as well, but I'm more likely to actually have a hand of some sort. Now, I don't consider raising from the button w/K5 stealing. This is a value bet. With just the blinds to act, King high may in fact be a gamer. Of course I'd be happy to win the hand right out, but I'm in position and not afraid of going HU against one of the blinds. If I get 2 calls, or a re-raise, the hairs on the back of my neck start to raise as well.
