21 Coach: Blackjack Strategy

Basic strategy is the mathematically optimal decision system for blackjack — it tells you the correct move (hit, stand, double down, split, or surrender) for every possible hand based on your cards and the dealer's up card.

21 Coach: Blackjack Strategy makes learning this strategy fun and interactive:

- Guess the correct move for every hand you're dealt
- Get instant feedback when you're wrong, and learn the right answer
- Use hints when you're stuck
- Learn to spot common traps like the insurance bet

Fully customizable to match the table you play at:
- Number of decks (1-8)
- Dealer stands or hits on soft 17 (S17/H17)
- Double after split (DAS)
- Surrender rules (early/late/none)
- Preset rule sets like Vegas Strip, Downtown, and European

Practice at your own pace with different skill levels (Beginner, Intermediate, Advanced) and practice modes (All Hands, Soft Hands Only, Pairs Only, Custom). Track your hands, guesses, and most frequent mistakes over time to internalize basic strategy — no memorization required.
