The shuffle in Blackjack can affect the game’s odds, especially for players who count cards. If a deck is rich in high cards (10s and aces) before the shuffle, players have a better chance of winning, but shuffling resets the deck, bringing the odds back to baseline. For most players, shuffling doesn’t significantly change the game’s odds since it resets the deck composition, making the game more predictable. However, for card counters, shuffling is crucial because it erases any advantage they might have gained by tracking the remaining cards. In casino settings with automatic shuffling machines, the odds are less predictable, as the deck is shuffled more frequently.
