Double Up ( blackjack)


To double down with less than 2X the original bet. Generally, when doubling is allowed, the player
does not have to actually double his bet, but may increase it by any amount up to (but not more than) the original bet.



Double Up ( poker )


1) Go all in and win the pot. "I was down to my last $100 when I doubled up." "He had a better six than
I did and I doubled him up." 2) Go half and half with a player on his buy-in to a game; usually preceded by
go; sometimes followed by up. When the player quits, he splits with the person with whom he went cow.
Sometimes the house goes cow with a player to enable him to get into a larger game than he could otherwise
afford, generally with the no altruistic purpose of filling what would otherwise be a shaky game.
At some point when the player (the house hopes) gets far enough ahead of the game, the house may
split him out, that is, remove half of his chips and put him on his own.
