Single-deck 3:2 basic strategy

A dedicated total-dependent chart for a single-deck H17 game where a natural still pays the full 3:2.

Reviewed by Casino Calculated Editorial TeamPublished September 21, 2026Last reviewed September 21, 2026
Bottom line: This is a 3:2 chart. The common 6:5 single-deck game is economically different even when many playing decisions match.

Profile

This chart assumes H17, 3:2 blackjack, double on any first two cards, DAS, no surrender, dealer peek, split to four hands, and no resplitting or hitting split aces.

Why the payout comes first

Single deck is not automatically favorable. A 6:5 payoff can overwhelm the deck-count benefit, so verify 3:2 before using the chart or judging the game.

Table check

  • Verify 3:2—not 6:5
  • Confirm H17
  • Confirm double after split
  • Use this chart only with dealer peek

How the chart is chosen

For each player state and dealer upcard, compare the conditional expected value of every legal action over the remaining-card distribution. The chart selects the action with the greatest expected value under the stated deck count, dealer rule, doubling, splitting, surrender and dealer-blackjack procedure.

Scope: These are rule-matched, total-dependent starting-hand charts—not composition-dependent charts. Exceptions can occur in one- and two-deck play. Insurance and side bets are excluded.
