For 6 and 8 deck games, double S13v5 and S15v4. The table above is for an infinite number of decks where double is allowed after splitting. This chart must be memorized solidly before one can expect to have edge over the house. When there are multiple letters in a cell (for example DH) it means to do the first thing if possible, otherwise the second. Note that two aces is S12 in this chart (and not P02 or anything else). Look up the row corresponding to your hand and the column corresponding to the dealer up card. The simulator here supports a few of the variations common at $100 minimum tables around Las Vegas and Atlantic City.

LS: Do you have an option to surrender after the dealer checks for blackjack?.

S17 vs H17: Does the dealer stand or hit soft 17?.

DAS: Are you allowed to double after you split?.

Try to get a higher point total than the dealer, but don't go over 21.
