I've never played Holde'em where there is a badbeat jackpot (they don't have any in Ontario). But in case I ever go to somewhere thathas it, I have a few questions:

is it only the person who loses who gets the entire jackpot or does his opponent get some of it? for example, if the jackpot is 50K, and player A has quad kings and loses to player B who has Quad Aces, does player A get 50 K or is it split somehow.
If the answer is that Player A gets all the money, then what happens if player B folds his winning hand (because he is an idiotor out of spite for player A)? Does that mean player A wins the pot but loses the jackpot because he now wins the hand??

Thanks in advance
