i was in ring game, i had pocket aces, another player kk and another 99, when i made a big raise i was surprised that another guy reraised me,and the third guy calleed,i knew that one of them had pocket kk or qq or even aces,so i just called, the flop was 9, 8. k.both mu opponents flopped sets,but of course i didn't know it, so i checked and waited to see where i am, the pocket kk guy, made a big bet,to my surprise the other guy reraised with set of 9,at this point i knew i was beat and throw my rockets in the mac, the guy with a small set lost all his chips.the odds to flop two sets was so small but it happened.
