Blackjack Basic Strategy Chart

Optimized for Duel.com rules: S17 (dealer stands on soft 17), infinite decks, no DAS (double after split)

Key Rules for Duel.com:
  • Always decline insurance - it's negative EV even against dealer Ace
  • Expected win rate: ~45% of hands with perfect basic strategy
  • Zero edge: Over time, EV = 0 with optimal play
  • Short sessions: Variance can work in your favor - aim for +$5 then stop
  • Infinite decks: Card counting doesn't work - focus on Basic Strategy
📊 How to Read These Charts:

Find YOUR hand total in the left column, then look across to the column matching the DEALER'S upcard. The cell shows the optimal play.

Example: You have Hard 15, dealer shows 6 → Find "13-16" row, look at "6" column → S = Stand

🎯 Critical Strategy Points (Based on Dealer Upcard):
Dealer Weak (2-6) - "Bust Cards"
  • Dealer 2-3: Stand on 13+, they'll likely bust
  • Dealer 4-6: Stand on 12+, highest bust probability
  • Double more: Dealer weak = aggressive doubling (9-11, soft hands)
  • Never hit stiff hands (12-16): Let dealer bust themselves
Dealer Strong (7-A) - "Pat Cards"
  • Dealer 7-A: Hit until you reach 17+ (they likely have 17+)
  • Dealer 10: Assume they have 20 - hit aggressively
  • Dealer Ace: Most dangerous - decline insurance, hit to 17+
  • Don't stand on 12-16: You'll lose to their likely pat hand
🔍 What to Look For in Your Play:
Common Mistakes to Avoid:
  • Hitting 12-16 vs dealer 2-6: Should stand - let dealer bust
  • Standing on 12-16 vs dealer 7-A: Should hit - dealer likely has 17+
  • Not doubling on 11: Always double vs 2-10 (hit vs Ace)
  • Splitting 10s: Never split - you already have 20!
  • Not splitting 8s or Aces: Always split these
  • Taking insurance: Always decline - negative EV
Track These Metrics:
  • BS Adherence: Aim for 90%+ - check "Followed BS" when logging
  • Win rate vs dealer upcard: Should win more vs 4-6
  • Double success rate: Doubles should win ~55% vs weak dealer
  • Bust rate on hits: If >30%, you're hitting too much on stiffs
  • Overall win rate: Should be 43-47% with perfect BS
⚠️ Duel.com Specific Reminders:
  • Infinite deck: Card counting is useless - stick to Basic Strategy
  • No DAS (Double After Split): Be more conservative with pair splits
  • S17 (Stand on soft 17): Slightly better for player than H17
  • Zero edge with perfect play: Your mistakes = house advantage
  • Variance is your friend: Short sessions (10-20 hands) can beat EV=0

💡 General Bankroll & Session Tips

Optimal Bet Sizing
  • Starting bankroll $35: Bet $2-$3 (5-10%)
  • Bankroll $50+: Can increase to $3-$5
  • Bankroll <$25: Drop to $1-$2 or stop

  • Consistency matters: Stick to same bet size per session
Session Management

  • Loss limit: Stop at -$7 to -$10 loss
  • Time limit: 20-30 minutes max per session
  • Game limit: 15-25 games then reassess
  • Break after streaks: 3+ losses = 5 min break
🎲 Understanding Zero Edge (EV=0)
What It Means

On Duel.com, the house has NO mathematical advantage. Over infinite plays, you'd break even. This is RARE - most casinos have 1-5% edge.

How to Exploit It

Short sessions leverage variance. You can win +$5-$10 before variance swings back. Long sessions → regression to EV=0 (break even).

The Catch

Discipline is everything. Chasing losses, over-betting, or ignoring strategy creates YOUR OWN house edge against yourself.

📊 Expected Outcomes (with optimal play):
10 games:
Win: 40-60%
Variance: High
25 games:
Win: 45-55%
Variance: Medium
50 games:
Win: 47-53%
Variance: Low
100+ games:
Win: ~50%
Variance: Minimal

Takeaway: Shorter sessions = higher chance to profit from variance. Longer sessions = closer to break-even.

🧠 Psychology & Discipline
Avoid These Behaviors:
  • Chasing losses: Doubling bets after losses
  • Overconfidence: Increasing bets after wins
  • Tilt playing: Emotional decisions after bad beats
  • Ignoring limits: Playing past stop-loss point
  • "One more game": Breaking your win goal
Winning Mindset:
  • Pre-set limits: Decide win/loss limits BEFORE playing
  • Celebrate small wins: +$5 is a successful session
  • Accept variance: Losing streaks happen even with perfect play
  • Track everything: Data reveals patterns you can't see in-game
  • Take breaks: Fresh mind = better decisions
✅ Ideal Session Checklist:
  1. Set win goal (+$5) and loss limit (-$7) BEFORE starting
  2. Choose game: Mines (M=3, K=3-4) or Blackjack with BS chart open
  3. Bet consistently: $2-$3 per game
  4. Log each game immediately in this tracker
  5. Check dashboard after every 5 games - are you on track?
  6. Stop when you hit win goal OR loss limit (whichever first)
  7. Review "Your Stats" tab to learn from the session
  8. Wait 1+ hours before next session (avoid tilt)
