Blackjack Counting Introduction 2 — Questions and Answers
Question 1: What is the primary purpose of card counting in blackjack?
- To memorize every card that has been played
- To track the ratio of high to low cards remaining in the deck (Correct answer)
- To predict the dealer's hole card
- To calculate the exact probability of busting
Correct answer: To track the ratio of high to low cards remaining in the deck
Card counting tracks the proportion of high cards (10s, aces) versus low cards remaining, allowing players to adjust bets accordingly.
Question 2: Which mathematical concept underlies all card counting systems?
- The law of large numbers
- Bayes' theorem
- Conditional probability based on card removal (Correct answer)
- The Fibonacci sequence
Correct answer: Conditional probability based on card removal
Card counting exploits conditional probability — removing cards from the deck changes the probabilities of future hands.
Question 3: Why do blackjack players have an advantage when the deck is rich in high cards?
- Dealers must hit on soft 17 more often
- Blackjacks pay 3:2 and occur more frequently, and dealers bust more often (Correct answer)
- The house edge disappears entirely
- Players can split more effectively
Correct answer: Blackjacks pay 3:2 and occur more frequently, and dealers bust more often
High cards increase blackjack frequency (which pays 3:2) and cause dealers to bust more since dealers must hit to 17.
Question 4: What does a 'true count' represent in card counting?
- The total number of cards remaining in the shoe
- The running count divided by the number of decks remaining (Correct answer)
- The count only of aces remaining
- The cumulative sum of all cards counted
Correct answer: The running count divided by the number of decks remaining
The true count normalizes the running count per deck remaining, providing an accurate picture of advantage regardless of shoe depth.
Question 5: Who is widely credited with first publishing a mathematically proven card counting system?
- Stanford Wong
- Ken Uston
- Edward Thorp (Correct answer)
- Arnold Snyder
Correct answer: Edward Thorp
Edward Thorp published 'Beat the Dealer' in 1962, introducing the first mathematically verified card counting system.
Question 6: What is the house edge in a typical blackjack game with basic strategy but without counting?
- 0% — the game is perfectly even
- Approximately 0.5% (Correct answer)
- Approximately 3–5%
- Approximately 10%
Correct answer: Approximately 0.5%
Basic strategy reduces the house edge to roughly 0.5%, and card counting can shift this to a player advantage.
Question 7: How does increasing deck count (e.g., 1 deck vs. 8 decks) affect card counting effectiveness?
- More decks make counting easier because the count changes less frequently
- More decks reduce the counter's advantage because count fluctuations are smaller relative to the shoe (Correct answer)
- Deck count has no effect on counting effectiveness
- More decks make it impossible to achieve a positive count
Correct answer: More decks reduce the counter's advantage because count fluctuations are smaller relative to the shoe
In multi-deck shoes, the true count changes more slowly, reducing the magnitude of the player advantage at any given count.
