The complete, mathematically optimal basic-strategy chart — for your exact rules.
Basic strategy is the set of mathematically best decisions for every hand in blackjack. Played perfectly it cuts the house edge to well under 1%. This chart is computed live for your table rules.
Blackjack basic strategy is the mathematically optimal way to play every starting hand. For any combination of your two cards and the dealer's up-card, there is exactly one decision — hit, stand, double, split or surrender — that maximises your expected value over the long run. The chart above lays out all of those decisions for your chosen rules.
Rows are your hand, split into three groups: hard totals (no ace, or an ace counted as 1), soft totals (a hand with an ace counted as 11, e.g. A-7 = soft 18) and pairs you may split. Columns are the dealer's up-card, 2 through Ace. Find the cell where your hand meets the dealer's card and make that move.
Yes. Perfect basic strategy is not a betting system or a trick — it is the proven baseline that every serious blackjack resource teaches. It reduces the house edge to roughly 0.5% under common rules and even lower with favourable ones. It will not make blackjack a guaranteed win, but it is the single biggest thing you can do to stop giving money away.
Reading a chart is one thing; recalling it under pressure is another. Use the basic strategy trainer to practise hand by hand with instant feedback, and check the exact house edge your rules produce.
