Shuffle tracking is a blackjack technique that can be used to increase the odds of winning. The basic idea behind shuffle tracking is to track which cards are being used during a shuffle, and then use this information to place bets accordingly.
There are a few different ways to go about shuffle tracking, but the most common method is to keep track of the cards as they are being shuffled. This can be done by paying attention to the order of the cards as they come out of the deck, or by keeping track of which cards are being dealt face up and which are being dealt face down.
Once you have a good understanding of which cards are being used during a shuffle, you can then start to place bets based on this information. For example, if you know that a certain number of high cards are going to be used in the next hand, you can bet accordingly.
Shuffle tracking takes a lot of practice and patience, but it can be a very effective way to increase your chances of winning at blackjack.
