Why Basic Strategy Is Your Best Bet
If you've ever sat at a blackjack table in a Philippine casino—whether at Solaire, City of Dreams, or an online site—you've probably seen players make questionable calls. Hitting a 15 against a dealer's 6? Splitting 10s? Those moves might feel lucky, but they bleed money over time.
Basic strategy is a mathematically derived set of decisions that tells you the optimal play for every hand combination. It won't guarantee wins, but it reduces the house edge to around 0.5%—far better than the 2-5% you'll face with hunches. This checklist distills the key rules so you can act fast without a cheat sheet.
Remember: Basic strategy assumes you're playing a standard game with 4-8 decks, dealer stands on soft 17, double after split allowed, and no surrender. Adjust if your table's rules differ.
The Core Rules: Hard Hands & Soft Hands
First, understand the difference. A hard hand has no ace, or an ace counted as 1. A soft hand contains an ace counted as 11 (so you can't bust with one more card).
Hard Hands: Hit or Stand?
- 8 or less: Always hit.
- 9: Double if dealer shows 3-6; otherwise hit.
- 10: Double if dealer shows 2-9; otherwise hit.
- 11: Double if dealer shows 2-10; hit against ace.
- 12: Stand if dealer shows 4-6; otherwise hit.
- 13-16: Stand if dealer shows 2-6; hit if 7 or higher.
- 17-21: Always stand.
That 12 vs. 4-6 stand is tricky—many players hit, but the math says stand. The dealer busts more often when showing 4-6, so you don't want to risk busting first.
Soft Hands: Play the Ace
- Ace-2 (soft 13) or Ace-3 (soft 14): Double if dealer shows 5-6; otherwise hit.
- Ace-4 (soft 15) or Ace-5 (soft 16): Double if dealer shows 4-6; otherwise hit.
- Ace-6 (soft 17): Double if dealer shows 3-6; otherwise hit. (If double not allowed, hit.)
- Ace-7 (soft 18): Double if dealer shows 2-6; stand if 7 or 8; hit if 9, 10, or ace. (Stand against 2-8 in some rule sets, but the double is better when allowed.)
- Ace-8 (soft 19): Always stand.
- Ace-9 (soft 20): Always stand.
Soft hands give you flexibility. Treat them as a chance to double when the dealer is weak.
Pair Splitting: When and When Not To
Splitting pairs can multiply your profit—or your losses. Follow these rules:
- Aces: Always split.
- 8s: Always split.
- 10s: Never split.
- 5s: Never split; treat as hard 10 (double if dealer 2-9).
- 4s: Split if dealer shows 5-6; otherwise hit.
- 3s, 2s, 7s: Split if dealer shows 2-7; otherwise hit.
- 6s: Split if dealer shows 2-6; otherwise hit.
- 9s: Split if dealer shows 2-6, 8, or 9; stand if 7, 10, or ace.
That last one surprises people. Standing on 9-9 against a 7 gives you 18, which beats the dealer's likely 17. Against a 10 or ace, you're better off standing and hoping the dealer busts.
Never split a pair of 5s—you have a strong 10, so double instead when the dealer is weak.
Doubling Down: Maximize Strong Situations
Doubling down lets you increase your bet in favorable spots. Use it aggressively when the dealer is weak.
- Hard 9: Double vs. 3-6.
- Hard 10: Double vs. 2-9.
- Hard 11: Double vs. 2-10.
- Soft 13-14: Double vs. 5-6.
- Soft 15-16: Double vs. 4-6.
- Soft 17: Double vs. 3-6.
- Soft 18: Double vs. 2-6.
If doubling isn't allowed (some online games restrict it), just hit. Also, never double on hard 12 or higher—you're too likely to bust.
Remember: Double after split (DAS) is common in Philippine casinos, so you can double on split hands. That makes splitting even more valuable.
Insurance and Surrender: Skip or Use?
Insurance is a side bet that the dealer has a blackjack. It pays 2:1, but the odds are against you—the dealer only has a 10-value card about 30% of the time. Always decline insurance. It's a suckers' bet.
Surrender, on the other hand, can be useful. If allowed, surrender hard 16 against a dealer's 9, 10, or ace, and hard 15 against a 10. You forfeit half your bet but avoid a likely loss. However, many Philippine tables don't offer surrender, so check the rules first.
If you're playing online, the software usually includes basic strategy hints. Use them to practice, but don't rely on them forever—internalize the checklist.
Quick tip: If you're new, print this checklist and keep it on your phone. Most casinos allow basic strategy cards at the table.
Frequently Asked Questions
Does basic strategy change with different blackjack rules?
Yes. The core rules are similar, but variations like dealer hits on soft 17, no double after split, or single-deck games require slight adjustments. For example, if the dealer hits soft 17, double more often on soft 18. Always check the table rules first.
Can I use a basic strategy card in Philippine casinos?
Generally, yes. Most land-based casinos allow you to refer to a basic strategy card. However, some may restrict phone use, so a printed card is safer. Online casinos often have built-in strategy hints.
Is basic strategy enough to beat the house?
No, basic strategy reduces the house edge to about 0.5%, but the house still has an advantage. To beat the house, you'd need to count cards, which is difficult and often banned. Basic strategy is about minimizing losses and maximizing winning sessions.
What if I make a mistake? How much does it cost?
Occasional mistakes won't ruin you, but consistent errors increase the house edge. For example, hitting a 16 against a 6 instead of standing can cost you about 2% in expected value. Practice makes perfect.
