Questions & Answers

Q: What is expectation and how does it affect gambling outcomes?

Expectation is the average amount a gambler expects to win or lose in a particular game. It takes into account the odds of winning and the payout if one wins. Expectation is negative for most casino games, meaning that players can expect to lose money in the long run.

Q: How does card counting work in blackjack, and how does it give players an advantage?

Card counting involves keeping track of the ratio of high cards (favorable to players) to low cards (favorable to the dealer) that are still in the deck. A higher ratio indicates that the remaining cards are more favorable for players, and they can increase their bets accordingly, increasing their chances of winning.

Q: Does card counting work in modern casinos?

Casinos have implemented measures to make card counting more difficult, such as using more decks, automatic shuffling machines, and closely monitoring betting patterns. It is challenging to be a successful card counter in modern casinos unless part of a team or exceptionally skilled at disguises.

Q: Are there other ways to profit from gambling besides blackjack and card counting?

Some promotions, new games, and rule variations provided by casinos or online betting sites may have positive expectation, offering players a small edge. Computerized calculations and finding small edges can also yield profits for skilled gamblers.
