Well, no matter which site you play on, AA seems to never want to hold up and it always seems to me KK only loses once in a great while even against each other. It usually seems as though the K will always hit against the AA. I had AA once against KK and the flop came A-K-4 so I was feeling pretty good (we were all-in so the cards were showing). But woudn't you know it....the last K came on the river. I just looked at it and gave out a laugh. You just gotta love poker.
