I think that's the thing that puzzles me th most about that hand. How much money does a guy have to call that kind of betting with a Q6? I mean, when you shoved he had KK66A. With all that betting and raising before the flop, just what exactly did he think he was ahead of or was gonna be ahead of? The best card he could of caught on the river was another 6 to give him 666KK. He doesn't think that SOMEONE has one K? I can almost see it (assuming it had been free to play the hand to that point) if he had QQ or 66. At least he had the top pair not on the board or a shot at quads, but Q6? My god, that is just insane.....(hey, my kicker beat SB's kicker).
In your spot, you just have to believe that they each had an Ace-big (AQ, AJ) hand. The more I think about that hand the more sick I get about it - and I wasn't even there!
