This happened on my .25/.50 table today. It was easily the worst beat I have ever put on someone, but the one he would have put on me if the river had been different was gonna be pretty damn bad.

I just called on the flop cause I had flopped top full house, and I figured these guys were all way behind, and that i would be better suited to raise the turn. Then the turn was a six, which was kind of unnerving, but the blind both checked to me, so I bet it. Then when it got three-bet coming back to me, I was feeling about the sickest I have ever felt with the top full house. I almost considering even laying it down, but I decided I just didn't have it in me to lay that down, not at .25/.50. Then the river was a seven, and I almost had a stroke. Just so no one thinks I'm an idiot for not capping that river, the BB's three-bet was only 15 cents, as he was all-in, and it wouldn't let me raise it, which sucked, as I had these other two suckers tagging along. Still, It was easily the biggest pot, in terms of BBs, that I have won. I am especially cracked up by the idiot tagging along with QJs.
