The worst bad beat I ever took in my poker history was getting beat holding quads. I had a pocket pair and flopped the quads and was looking to get some more chips into the pot for a hand I figured was mine.
My opponent also had a pair and caught something on the flop, which was good news for me since he now had a full house to my quads, but the river gave him his 4 of a kind.
OUCH!
