Blackjack
Every hand, answered

340 decisions. One page each.

Pick your hand and the dealer’s upcard. Each page gives the basic-strategy move, why it is right under the stated rules, what to do if doubling or splitting is unavailable, and the full row for comparison.

Training rules: six decks · dealer stands on soft 17 · no surrender

This is a separate educational profile. Rules can differ between app tables and other games.

  • Six decks. Dealer stands on all 17s, including soft 17.
  • US hole card and peek: decisions assume the dealer has checked and does not have blackjack.
  • Double any first two cards, including after splitting. Doubling ends the hand after one extra card.
  • Split equal card values into at most four hands. Split aces receive one card each; no resplitting aces.
  • No surrender. A natural blackjack pays 3:2; 21 after splitting is not a natural.
  • Total-dependent strategy. No card counting or expected-value estimates.

The same decisions as a chart

Choose the pair table first for a splittable pair, then soft or hard totals. H = hit, S = stand, D = double, P = split. If doubling is unavailable, hit; for soft 18, stand instead. Select any cell for the reasoning behind it.
