DS is the term used to describe the difference between the dealer’s advantage and your edge on blackjack. On a standard 52-card deck, the dealer has an advantage of about 0.
8% over the player. This means that for every 100 hands played, the dealer will lose about 80 hands and win 20. .
Your edge on blackjack is determined by your personal playing strategy, which may include counting cards, sticking to rules-based strategies, or using certain blackjack hands as “insurance” shots. As long as you are playing within the limits set by the house (i.e.
, no more than 2% edge for American blackjack and 3.6% for European blackjack), your edge will be constant regardless of whether you are playing with a DS or not.
