There is much debate surrounding this question, with some believing that dealers do indeed shuffle after every hand, while others maintain that the practice is not universal. The majority of casinos use a random number generator to determine the order in which cards are dealt, so it is difficult to determine with certainty whether or not dealers actually shuffle after every hand.
Some proponents of the shuffle-after-every-hand theory argue that it helps to improve the fairness of the game. By randomly mixing the cards, it is believed that dealers will have a harder time predicting the hands of other players and will therefore be less likely to cheat.
Furthermore, it is argued that shuffling also helps to reduce the amount of noise in the casino, making it easier for players to hear their dealer.
However, opponents of the shuffle-after-every-hand theory argue that it can create more chaos and confusion in the casino. In particular, they argue that dealers may become more careless and may make more mistakes when dealing cards if they are constantly shuffling them.
Furthermore, opponents of the shuffle-after-every-hand theory argue that players who are good at predicting which cards will be dealt next can take advantage of this by playing more conservatively in order to avoid getting carded.
Ultimately, there is no definitive answer as to whether or not blackjack dealers shuffle after every hand. However, based on the arguments put forward by both sides, it seems likely that most casinos do not actually perform this procedure on a regular basis.
