1. Card counting can provide an edge in blackjack, but online casinos use various techniques to counter it like reshuffling frequently, slowing the dealing speed, and restricting penetration.
2. Shuffle tracking, which predicts the count after a shuffle based on how the dealer shuffled, may provide an even greater advantage than card counting alone if done accurately.
3. New software aims to track every card by exact value and suit, dynamically adjust strategy based on the remaining cards, and potentially predict shuffles, in an effort to overcome casino countermeasures and achieve a long-term winning strategy for online blackjack.
