Player's Hard 20 vs Dealer's 10 — Best move (Basic Strategy)
You have Hard 20 and the dealer shows 10. The optimal basic strategy move under common U.S. casino rules is below.
Scenario Overview
You’re sitting on a hard 20 (like 10+Q), and the dealer is showing a 10. In the classic player hard 20 vs dealer 10 spot, your hand is already one of the strongest totals you can have without being a natural 21. This is exactly the kind of moment where blackjack basic strategy keeps things simple: protect your big number and let the dealer do the risky work.
Key Constraints & Objectives
Your objective isn’t to “beat the dealer’s 10” directly—it’s to maximize long-run value. With a hard 20 blackjack decision, the key constraint is bust risk: any hit can easily turn a near-lock into an instant loss. A basic strategy chart exists to remove guesswork here, and it consistently prioritizes preserving strong totals over chasing an unnecessary extra point or two.

Best move: STAND. Across generally applicable blackjack basic strategy guidance, you stand on hard 20 regardless of the dealer’s upcard, including a dealer 10 upcard strategy situation. Your total is already high enough that improving it is unlikely, while damaging it is very easy.
Reasoning and Tradeoffs
Standing on 20 minimizes risk and maximizes your chance to win when the dealer makes a weaker hand or busts. In player hard 20 vs dealer 10, the tradeoff is emotional more than mathematical: the dealer’s 10 looks scary, but your hand is still excellent. You’re not trying to “get safer”—you’re already safe. The dealer must complete their hand, and that process creates opportunities for you to win without taking on extra danger.
Why Not Other Options
Hitting is the big trap. With 20, you only improve with an Ace (to 21); almost everything else breaks your hand, which is the opposite of avoid busting in blackjack. Doubling down is also unnecessary: you’re already at a premium total, and adding a forced draw introduces needless volatility. If you use a basic strategy chart, this is one of the clearest “do not get fancy” moments—stand and let the dealer resolve the hand.
Quick Checklist / TL;DR
- On player hard 20 vs dealer 10, the correct play is to STAND.
- Hard 20 is strong; hitting usually turns a winner into a bust.
- Blackjack basic strategy (and any basic strategy chart) treats 20 as a protected total.
Common Mistakes
- Hitting because the dealer shows a 10 and it “feels” dangerous.
- Trying to improve 20 even though only an Ace helps and most cards bust you.
- Ignoring the basic strategy chart and making a reactive, fear-based decision.
