Deal one up card to each player, followed by a down card to the dealer.Then deal a second up card to each player, followed by the dealer's up card. Make sure the cards are laid out diagonally so that both numbers on each card are visible. This makes it easy for both the player and the dealer to read the cards.
If the dealer is showing a Two, Three, Four, Five, or Six, he is more likely to bust. The Five and the Six are the cards most likely to lead to a busted hand for the dealer. In this case, the player doesn't have to take big risks to try to get closer to 21 -- he simply needs to avoid busting himself.
