How do you play Blackjack?
Get as close to 21 as possible without going over. Beat the dealer's hand. Face cards are worth 10, Aces are 1 or 11.
What is card counting?
Card counting is a strategy where you track high and low cards to determine when the deck favors the player. The Hi-Lo system assigns +1 to 2-6, 0 to 7-9, and -1 to 10-Ace.
When should I split in Blackjack?
Always split Aces and 8s. Never split 10s or 5s. Split 2-3 and 6-7 against dealer 2-7. Split 4s against dealer 5-6. Split 9s against dealer 2-6 and 8-9.
