Card counting is a strategy employed by skilled blackjack players to gain an advantage over the casino. It involves keeping track of the ratio of high-value to low-value cards remaining in the deck or shoe. This information helps players adjust their bets and playing decisions to maximize their chances of winning.

The concept behind card counting is based on the fact that certain cards, particularly high-value cards like tens and aces, are more favorable for the player, while low-value cards like 2s through 6s are more favorable for the dealer. When the remaining deck has a higher proportion of high-value cards, it increases the likelihood of the player getting blackjack, doubling down successfully, and the dealer busting.

Here's how card counting typically works:
  1. Assigning Values: Players assign a value to each card in the deck. A common system uses +1 for low cards (2-6), 0 for neutral cards (7-9), and -1 for high cards (10s and aces).
  2. Keeping a Running Count: As cards are dealt, players mentally keep a running count based on the assigned values. They start with a count of 0 at the beginning of the shoe.
  3. Calculating the True Count: To account for the number of decks remaining in the shoe, players divide the running count by the estimated number of decks left. This gives them the true count, which is more accurate for making betting decisions.
  4. Betting Strategy: Players increase their bets when the true count is positive (indicating a player-favorable deck) and decrease or bet the minimum when the true count is negative (indicating a dealer-favorable deck).
    Card counting can indeed work and provide an advantage to skilled players. However, it's essential to understand several critical points:

    1. Skill Requirement: Successful card counting requires significant skill, practice, and mental acuity. Players must accurately keep track of the count while also making optimal playing decisions.

    2. Legality: Card counting is not illegal, but casinos frown upon it. If a casino suspects a player is counting cards, they may ask the player to leave or ban them from playing blackjack.

    3. Variability: Card counting doesn't guarantee winning every hand. It merely shifts the odds in the player's favor over the long term. Short-term results can still be influenced by luck.
  5. 4Rule Variations: The effectiveness of card counting can vary depending on the specific blackjack rules in use, such as whether the dealer hits or stands on a soft 17.


 
The basic idea is to keep track of the cards that have been played, so that the player can predict when the deck is rich in high cards or low cards. By knowing the deck composition, the player can make more informed decisions about when to hit, stand, split, or double down. While card counting can be effective, it's not as easy as it may seem.
 
I think Card counting does work in theory, but it is not foolproof. To be an effective card counter, one must have a keen mental ability to track cards and calculate probabilities, as well as the discipline to follow proper betting strategies.

It could be something feasible for someone joining the table from the beginning. So what about someone who joins the table in the middle of time or even at the end of the tournament it seems something not feasible in online blackjack rooms you could have one player left and one player entering in the middle or even end of the game.
