Single Deck Blackjack Strategy Chart

  • 1 deck
  • Dealer hits soft 17
  • No double after split
  • Double any two
  • No surrender
  • Blackjack pays 3:2
  • House edge +0.34%

The chart for the classic Vegas pitch game: one deck, dealer hits soft 17, double any two cards — but no double after split and no surrender, the trade almost every real single-deck table makes. With a 3:2 blackjack it's one of the lowest-edge games on the floor (+0.34%). Every cell is generated for exactly these rules by the engine behind the free blackjack trainer; the standard shoe chart lives at the 6-deck basic strategy chart.

No surrender cells appear because this game doesn't offer it. If your single-deck table does allow DAS or surrender, flip those rules in the interactive chart and the grid regenerates.

What changes vs the 6-deck chart

Coming from the standard shoe chart (6 decks, H17, DAS, late surrender), these are the 19 cells that play differently at this table — computed by diffing the two charts in the engine, with the rule that drives each change. Fewer decks make doubling stronger (each card you remove swings the composition more), while the no-DAS and no-surrender rules pull some splits and surrenders back to hits — and the pack is small enough to produce the famous single-deck oddity: stand on 7,7 against a ten, because two of the sevens you'd need are already in your hand.

The 6:5 trap

Most single-deck tables on the floor today pay blackjack 6:5 instead of 3:2 — and that one line of felt costs more than every other rule combined. This exact game at 6:5 carries a +1.73% house edge, worse than almost any 3:2 shoe game. The single-deck advantage is real only at 3:2; if the sign says 6:5, walk to the shoe game.

Single-deck questions

Why does the deck count change strategy at all?

Card removal. With one deck, the cards already dealt shift the remaining composition sharply — your 6,5 double against a 10 is stronger when the two small cards in your hand came out of just 52. That's why single-deck strategy doubles and splits more aggressively than shoe strategy in the borderline cells above.

Is single deck the best game in the casino?

At 3:2 with these rules it's close to the top (+0.34%), though a 6-deck S17 DAS LS game runs about the same and is far easier to find honest. At 6:5 it's one of the worst. The payout line matters more than the deck count.

Does counting work better with one deck?

Yes — the true count swings faster and further. Once this chart is automatic, the deviation chart shows the count-based index plays, and the trainer's single-deck mode deals the real thing, shuffle timing and all.
