Here is the table for single deck without the option of doubling down after splitting. I have highlighted the decisions that should never change because of the number of decks, doubling rules or splitting rules. The yellow boxes represent the decisions of hitting, doubling down and splitting that should never change. For the sake of simplicity, I haven’t included the affected surrender decisions. If your boss gives you a basic strategy table that differs from one you have already memorized, if would be willing to bet that the differences are in the borderline decisions that aren’t highlighted on this chart.
