Question: This was the worst beat I ever had. I'm playing in a no limit game. I get pocket aces so I raise pre flop. Another player re-raises me and a third goes all-in. I go all-in next and the third guy goes all in. The flop comes: Ah, Jh, 9s. So now I'm feeling real good right? I got the nuts trip aces. Next comes the turn: Js. Ok, this is great right I figure I just won a huge pot with three of us all-in. I have a full house Aces over Jacks. Can't beat that right? Wrong. The river is a 10h. Ok so I have the full house. Wanna guess what the other two have?? Pocket jacks and KQh. That's right dude. I got beat by both four of a kind and a Royal Straight Flush all in the same hand!!! Any idea what the odds of that happening is? I've lost a lot of all-ins, but I don't thing anything will ever beat that one. Just figured I'd share that one with everyone. The good new is it was only a .25/.50 game with a max buy-in of $50. I lost about $45.
