Card counting in blackjack is a strategy where players track the ratio of high cards (10s, face cards, and Aces) to low cards (2-6) remaining in the deck. By keeping a mental tally of the cards that have been dealt, players can estimate when the deck is favorable to them, meaning more high cards remain. This allows them to increase their bets when the odds are in their favor and adjust their playing decisions accordingly. While not illegal, casinos monitor for card counters and may ask them to leave. It requires practice and is most effective in games with fewer decks and less frequent shuffling.
 
Card counting in blackjack is indeed a strategy that involves the tracking of the ratio of high cards to low cards in a deck or shoe. By keeping track of which cards have been dealt, players can gain insight into the composition of the remaining cards and adjust their bets and playing decisions accordingly.

The high cards (10s, face cards, and Aces) are favorable to players because they increase the likelihood of getting a natural blackjack (a 2-card hand totaling 21) and increase the chances of the dealer busting. On the other hand, low cards (2-6) benefit the dealer by reducing the likelihood of busting.

As the game progresses and cards are dealt, card counters assign a point value to each card. For example, high cards are assigned a value of -1, low cards are +1, and neutral cards (7-9) are assigned a value of 0. By keeping a running count of these values in their heads, players can estimate the "count," which indicates when the remaining cards are favorable for them.

When the count is high and favorable to the player, indicating that there are more high cards remaining in the deck, the player can increase their bets to take advantage of the favorable odds. Conversely, when the count is low and unfavorable, the player can decrease their bets or play more conservatively.

Card counting is not illegal, but casinos frown upon the practice and may ask suspected card counters to leave the premises. To counteract card counting, casinos often use multiple decks and employ frequent shuffling to minimize its effectiveness.

Overall, card counting is a skill that requires practice, focus, and concentration. It is most effective in games with fewer decks and less frequent shuffling, where the player's ability to track the cards can have a more significant impact on the game's outcome.
