Blackjack Soft Hands — Soft 17 & 18 Strategy

A soft hand counts an Ace as 11, so it can't bust on the next card — A,6 is "soft 17", A,7 is "soft 18". That flexibility means soft hands are played far more aggressively than the same hard total, and they trip up most casual players.

Soft 17 (A,6) — never just stand

Soft 17 is a trap: a hard 17 stands, but soft 17 should always be improved. Double against dealer 3–6; otherwise hit. Standing on soft 17 throws away EV.

Soft 18 (A,7) — the three-way hand

This is the most misplayed hand in blackjack:

  • Stand vs dealer 2, 7, 8 — your 18 is already ahead or even.
  • Double vs 3–6 (hit if doubling isn't allowed) — press your edge.
  • Hit vs 9, 10, A — 18 is a loser against a strong dealer card; draw to improve.

Soft 13–16 (A,2 through A,5)

Always hit, and double against the dealer's weak cards — see the cut-offs in when to double down. You can never bust, so there's no reason to stand on these low soft totals.

Soft 19+ — stand

Soft 19 (A,8) and soft 20 (A,9) stand. The one nuance: under H17 rules, double soft 19 vs a dealer 6.

Rules and the dealer's own soft 17

Whether the dealer hits or stands on soft 17 (H17 vs S17) changes several of your soft-hand cut-offs and adds about 0.2% to the house edge. Fullcount computes the exact EV for each soft total under your game:
