Playing Deviations are times when the true count dictates a decision that differs from Basic Strategy. Basic Strategy is the default correct playing decision for every possible hand combination in Blackjack.

When blackjack deviations concern how one bets at the blackjack table, these are known as betting deviations. Sometimes a change to the betting scheme can be a simple aspect of money management. Knowing how to properly use a betting bankroll is very important if one decides to make blackjack a serious endeavor.

Notes
- A 'Charlie' is an automatic winner. For example the five-card Charlie rule means the player automatically wins with 5 cards, as long as he didn't bust.
- Dealer does not peek for blackjack with an ace up. If dealer has a ace-up blackjack, player loses all bets made, including from doubling and splitting. A 10-up blackjack will be revealed immediately after peeking, and the player will lose only his original wager, except a blackjack tie will push.
- BB+1 refers to an Australian rule, in which the player will lose all busted bets, plus one unit, if the dealer gets a blackjack. For example, if the player splits 8's to three hands of a 20, (doubled) 19, and a busted hand, and the dealer get a blackjack, then the player will lose 2 units, one for the busted hand, and one from the remaining 3 units on the table. There is a great deal of confusion for the term for his rule, some sources calling it 'OBBO,' for Original and Busted Bets Only.
- OBBO stands for Original Bets and Busted Only. 'Original Bets' means each original bet per hand. So, if the player bet $5 and split to three hands, he would have three original bets of $5 each. As far as I know, the OBBO rule is confined to some parts of Australia and Malaysia. In the example above, the player would lose 3 units under this rule, one for the busted hand and two for the number of unbusted hands. The term is discussed in depth in the bookThe Pro's Guide to Spanish 21 and Australian Pontoon by Katarina Walker.
- This strange rule is actually followed in Pennsylvania, on Shufflemaster TMS-300 video multi-player blackjack games. State law prohibits one player taking the cards of another player. The way they implement this rule is to give every player, and the dealer, a separate shoe. The dealer plays out his hand first, secretly, and the results stored in memory. Then the cards used by the dealer are removed for each player shoe. When all players have finished acting, the game shows what cards the dealer drew already. According to Shufflemaster, the effect of this rule is 0.02% in favor of the dealer. Shufflemaster wishes to add this rule is part of a patent-pending technology.
- Dealer does not peek for blackjack with a 10 up. If dealer has a 10-up blackjack, player loses all bets made, including from doubling and splitting. An ace-up blackjack will be revealed immediately after peeking, and the player will lose only his original wager, except a blackjack tie will push.
- Dealer does not take a hole card, or never peeks at it if he does. If the dealer has a blackjack, then player loses all bets made, including from doubling and splitting, except a blackjack tie will push. The cost of this rule to the player is 0.08% when doubling, and 0.03% when splitting. This breakdown is important in the case of Galaxy casinos in Macau, where the player only loses the original bet when doubling, but everything when splitting, if the dealer gets a blackjack.
- The push on a dealer 22 rule is a legally protected rule. The rights belong to the owner of Blackjack Switch.
- This rule can be found at the Pharaoh's Palace in Macau. The player may invoke the rule before the dealer checks for blackjack. The effect shown is based on the dealer not taking a hole card.
