All I could think looking at the flop is I know this guy is a LAG, he plays 1/4 of his hands and bluffs every other hand he plays, and my KK is an investment so i called.

While I realize this should go in the bad beats section, the point here is do you usually go all the way with your AA KK AK when faced with situations and players like this? I just couldn't bring myself to throw it away.
