If Ddas Is Allowed, Will We Split Pairs More Frequently?
The presence or absence of DDAS (doubling down after split) will have an effect on what basic strategy decisions one makes with regard to splitting pairs. The pairs splits which it will affect, specifically, are the 2's, 3's, 4's and 6's. With DDAS allowed, the player will split twos and threes when the dealer shows the upcards of 2 through 7. A pair of 4's are split when the dealer shows a 5 or 6, and 6's are split when the dealer shows 2 through 6. Logic dictates that when DDAS is allowed, the player will split more, and when it is not allowed, the player will split less. Therefore, when DDAS is NOT available, 2's and 3's are split only when the dealer shows a 4 through 7, sixes are split against a dealer's 3-6 (rather 2-6), and 4's are not split at all.
Because of the fact that this rule alters the Basic Strategy, it is strongly suggested that all players come to memorize the variations on basic strategy which should be applied. Also make an attempt to know whether the casino you're patronizing offers DDAS, so that you can make your adjustments accordingly. If you are doing basic strategy drills at home, next to the appropriate splitting rules, denote in parenthesis the proper decisions for each rule when DDAS is not in effect. If you learn and unerstand the DDAS rule and are prepared for it, you'll "double" your fun, I promise.
