How to Play a Pair of 2s

May 24, 2021

Here is an example. Suppose you are playing a six-deck game with DAS and you are dealt a pair of 2s. The dealer’s upcard is a 4. If you hit, you have a negative expectation of winning. However, if you split, you expectation of winning is positive. Pair splitting is, therefore, the preferred option over hitting because it turns a negative expectation into a positive expectation (criterion #3 above).

Here’s another example. Suppose you are playing a double-deck game with NDAS. You are dealt a pair of 2s and the dealer is showing a 2 upcard. Whether you split or hit, your expectation is negative; however, hitting has a lower negative expectation than splitting, meaning you will lose less money in the long run if you hit (criterion #2).

The reason you split 2s against a dealer’s 2 and 3 upcard when DAS is allowed (double- and multi-deck game) is because the latter is a player-favorable rule that allows you to double your bet if you were to receive a favorable draw card on one or both of your split hands (such as a 9 plus 2 equals 11). To take full advantage of DAS, you split 2s not only against the dealer’s 4, 5, 6, or 7 but also against the dealer’s 2 and 3 upcards.
