Blackjack Basic Strategy Chart for French Rules Variants (2026)

Basic strategy is the mathematically optimal decision for every possible blackjack hand combination. It’s not a system, a hunch, or a shortcut — it’s the result of computing the expected value of every possible action (hit, stand, double, split, surrender) for all 550 unique player-dealer hand combinations and selecting the action that minimizes expected loss or maximizes expected gain.

The difference between playing « by feel » and playing perfect basic strategy is approximately 2-4% house edge reduction. A casual player facing a 3-5% house edge can bring it down to 0.5-0.7% with basic strategy alone. On a €25 average bet over 200 hands per session, that’s saving €100-€170 in expected losses per session. Basic strategy is free money left on the table by everyone who doesn’t use it.

This chart is specifically optimized for French (European No Hole Card) rules, which differ from American Hole Card rules in critical ways that affect strategy for approximately 15% of hand combinations.

French Rules Overview: What Makes Them Different

French-facing online casinos predominantly use European-style rules. Understanding the specific rule set is essential because strategy changes depending on the rules in play. The standard configuration at most French-facing offshore casinos is:

• No Hole Card (NHC): The dealer takes only one card face-up initially. No peek for blackjack. This is the defining French rule difference.
• 6 or 8 deck shoe: Most online blackjack uses 6 or 8 decks. Single-deck games are rare online.
• Dealer stands on soft 17 (S17): The more player-friendly variant. Some casinos use H17 (hits soft 17), which adds approximately 0.22% to the house edge.
• Double on any two cards or Double on 9-11 only: Varies by casino. Restricted doubling adds ~0.09% to house edge.
• Split up to 3 times (4 hands): Standard. Some casinos limit to one split.
• No surrender: Most French-facing casinos don’t offer surrender. When available, it reduces house edge by ~0.08%.
• Blackjack pays 3:2: Essential. Never play 6:5 blackjack — it adds 1.4% to house edge.

The No Hole Card Adjustment

The No Hole Card rule’s impact is often underestimated. In American-style blackjack, the dealer checks for blackjack immediately when showing an Ace or 10. If the dealer has blackjack, the hand ends and you only lose your original bet — doubled bets and splits are returned.

In NHC (French rules), you don’t know the dealer has blackjack until after you’ve acted. If you double or split, and the dealer subsequently reveals blackjack, you lose all money on the table — including the doubled or split portions. This changes several key strategy decisions:

• Don’t double 11 vs dealer Ace (hit instead)
• Don’t split 8-8 vs dealer Ace (hit instead, or surrender if available)
• Don’t double soft 19 (A-8) vs dealer 6 (stand instead)
• Don’t split A-A vs dealer Ace at some configurations (depends on payout rules)

These NHC adjustments reduce approximately 3-4% of hands from their American strategy counterpart. Small in frequency, but each misplay against a dealer 10 or Ace carries significant expected value cost.

The 10 Most Costly Strategy Mistakes

Not all mistakes cost equally. Here are the ten most expensive deviations from basic strategy, ranked by expected value cost per occurrence:

Eliminating just the top three mistakes — standing on 16 vs 7, not doubling 11 vs 6, and not splitting 8s vs 6 — saves approximately 0.3% of overall house edge for a typical player. That’s more than a third of the total gap between intuitive play and perfect strategy, concentrated in just three decision points.

Adapting Strategy for Online Casino Variants

Online casinos offer blackjack variants that modify standard rules. Each modification shifts optimal strategy. The most common variants at French-facing casinos:

Blackjack Surrender: Adds the option to forfeit half your bet before acting. Surrender is correct for hard 16 vs dealer 9, 10, or Ace, and hard 15 vs dealer 10. This single option, used correctly, reduces house edge by approximately 0.08%.

Double Exposure Blackjack: Both dealer cards are dealt face-up. Dramatically changes strategy — you now have perfect information about the dealer’s hand. However, the game compensates by paying even money on blackjack and requiring dealer wins on ties, resulting in a higher overall house edge (~0.69%) despite the information advantage.

Infinite Blackjack (Evolution): Unlimited seats, all players share the same hand and make individual hit/stand decisions. Uses standard NHC rules with an added « Six Card Charlie » automatic win. The side bets (Hot 3, Any Pair, 21+3, Bust It) carry 2-13% house edges and should be avoided.
