Blackjack 21 Puzzle

Blackjack is a card game that pits the player against the dealer. It is played with one or more decks of cards. Cards are counted as their respective numbers, face cards as ten and ace as eleven or one (in our game it will show up on the counter as 11 unless you are over 21). The object of Blackjack is to beat the dealer. This can be achieved by getting Blackjack (first two cards equal 21) without the dealer's Blackjack, making your final card count greater than the dealers without exceeding 21, or not exceeding 21 and the dealer removing upon exceeding his count of cards of 21.
