The first is a pair that includes one of your hole cards and your Upcard.
The dealer's Upcard is a 2 through Queen, and equals one of your own cards.
This number indicates the average number of players that stay in until they receive their second Upcard.
This is because the other
players will assume you have a pair of whatever your Upcard happens to be.
If the dealer's Upcard is an ace,
the player is offered the option of taking"insurance" before the dealer checks the hole card.
If the dealer's Upcard is a poor one,
4, 5, or 6, you should stop drawing as soon as you get a total of 12 or higher.
Winning tactics in Blackjack require that the player play each hand in the optimum way,
and such strategy always takes into account what the dealer's Upcard is.
At the point when the dealer's Upcard is a poor one,
4, 5, or 6, the player should quit drawing when he gets an aggregate of 12 or higher.
When the dealer's Upcard is a good one,
a 7, 8, 9, 10-card, or ace for example, the player should not stop drawing until a total of 17 or more is reached.
At the point when the dealer's Upcard is a decent one,
a 7, 8, 9, 10-card, or ace for instance, the player ought not quit drawing until the point when a sum of 17 or more is come to.
