Most strategy charts online show one frozen table and never tell you which rules it assumes. This one is generated live by the same engine that powers our blackjack trainer: pick the number of decks, S17 or H17, double after split and late surrender — and every cell recomputes. Cells that flip between rule sets (11 vs ace, soft 18 vs 2, soft 19 vs 6, 8-8 vs ace with surrender) are exactly where most players lose money with the wrong chart.
Memorize it with the free blackjack trainer — it checks every decision you make against this chart and explains your mistakes — then measure what perfect play is worth with the built-in million-hand simulator.
It is the mathematically optimal decision for every combination of your hand and the dealer's upcard — hit, stand, double, split or surrender — computed to minimize the house edge. Played perfectly, basic strategy cuts the house edge to roughly half a percent under good rules.
Yes. Whether the dealer hits or stands on soft 17 (H17/S17), whether you can double after splitting (DAS), and whether late surrender is allowed all flip specific cells — for example 11 vs ace and soft 18 vs 2. This chart regenerates live from the rules you select instead of showing one frozen table.
Find your hand on the left (hard total, soft total, or pair) and the dealer's upcard on top. The cell color tells you the play: H hit, S stand, D double (else hit), Ds double (else stand), P split, R surrender. Hands of 5-7 always hit and hard 18+ always stands.

Fictional practice only. Basic strategy minimizes the house edge but does not beat the game by itself; card counting on top of perfect basic strategy is what creates a player edge. 18+.
