Dealer Advantage (poker)
In a draw poker game, before the draw, the dealer gets information
about how everyone
bets before it is his turn to act, at the draw, about how many
cards they take, and, again,
after the draw, about how they bet. In hold 'em-type games in
which the betting each round proceeds from the dealer's left
and around, the dealer finds out how each player acts on his
hand before himself having to act. This positional edge is called
dealer advantage.
