The "high-lows" variation in blackjack typically refers to the Hi-Lo card counting system, where cards are assigned values to help players track the composition of the deck. Low cards (2-6) are given a +1 value, high cards (10, Jack, Queen, King, Ace) are given a -1 value, and neutral cards (7-9) are valued at 0. By keeping a running count, players adjust their bets and strategy based on whether the deck is rich in high or low cards. A positive count suggests more high cards are left, which is advantageous for the player, leading them to increase their bet and make more aggressive plays. Conversely, a negative or neutral count indicates the deck is rich in low cards, prompting players to bet less and play more conservatively. This strategy aims to give players an edge by capitalizing on favorable deck compositions.
 
The Hi-Lo card counting system is a popular and effective method used by blackjack players to gain a statistical advantage over the casino. By tracking the ratio of high cards to low cards that have been dealt, players can adjust their playing strategy and betting decisions accordingly. The idea behind the system is that high cards favor the player because they increase the probability of getting blackjack, while low cards benefit the dealer as they make it less likely for the dealer to bust.

When the count is high (positive), it indicates that there are more high cards remaining in the deck, which is advantageous for the player. In this situation, the player should increase their bets to take advantage of the higher likelihood of getting strong hands like blackjack and 20s. They can also adjust their playing strategy by being more aggressive, such as doubling down and splitting pairs more frequently.

Conversely, when the count is low (negative), it means that there are more low cards left in the deck, which is unfavorable for the player. In this case, the player should decrease their bets to minimize losses since the likelihood of getting strong hands is lower. Players might also choose to play more conservatively by avoiding doubling down and splitting pairs when the count is heavily negative.

Overall, the Hi-Lo card counting system helps players make more informed decisions based on the composition of the deck, allowing them to capitalize on favorable situations and minimize losses when the odds are against them. It is important to note that card counting is not illegal, but casinos may ask players to leave if they are caught counting cards, as it gives players an advantage over the house.
