Los Angeles bad beaters
All of the card clubs aroud LA play roughly the same format for their bad beat (hold 'em) jackpots - its gotta be A full of T (sometimes J) or better beaten by quads or better, both hole cards must play. My usual haunt (Hawaiian Gardes) pays out a minimum of 2K on the $1/$2, $10K on the $2/$5, with payouts during bonus time reaching $100K - 60% to the losing hand, 20% to the winner, and the rest shared amongst the table.
I remember one guy throwing a fit because the board showed AAA76, and he was all-in with pocket J's. Unfortunately, I had A5, winning the $200 or so pot, but "cheating" him out of 60 grand because my second hole card didn't play. I still say it was his fault for going all-in on the flop. Either he should have figured he had the best hand and slow-played, or figured it was a jackpot-hand and checked down to the river. I would have checked to the turn, at least, because the jackpot could have been in if it turn/rivered 5 or under. Most players seem to agree that if you're in jackpot territory you should check down, and its usually understood that a bet in this situation means you have the nuts but can't make the jackpot.
