Blackjack table

Soft 20 (A-9) is nearly unbeatable; basic strategy says stand against any dealer upcard, including a King.

Hard 11 against a dealer King in a 6-deck, S17 game is a hit per basic strategy; doubling is only favored against weaker upcards here.

Hard 12 against a dealer 10 is a basic-strategy hit; standing leaves the hand too likely to lose to the dealer's likely 20.

Hard 13 against a dealer 7 is a basic-strategy hit; standing risks losing to a likely dealer 17-20, while one card cannot bust me.

Soft 17 against a dealer 10 is a clear hit per basic strategy; standing loses to most dealer outcomes and doubling is not warranted with A-6 vs 10.

Hard 12 against a dealer 10 is a basic-strategy hit; standing loses to any dealer 12+ while hitting only busts on a 10.

Hard 20 against a dealer 7 is a clear stand; only a dealer 8/9/10 draw can beat it, and hitting or doubling risks a near-certain winning hand.

Hard 20 is a near-made hand; standing wins the vast majority of the time against a dealer 5. Doubling or splitting tens would recklessly risk a dominant hand.

Hard 15 against a dealer 2 is a standing hand in basic strategy (6 decks, S17); the dealer's bust risk on small upcards outweighs the risk of busting on a hit.

Basic strategy: hard 18 vs dealer 10 is a marginal hand; hitting loses less long-term than standing since dealer 10 upcard frequently makes 19-20.

Hard 9 against a dealer 10 is a clear hit; doubling is only correct against weak upcards 3-6, and standing loses to the dealer's likely 20.

Hard 19 is a strong made hand; standing is clearly optimal against a dealer 10 since hitting risks busting for negligible gain.

Hard 7 against a dealer 2 is far too weak to stand or double; basic strategy says hit until reaching a safe total.

Hard 16 versus a dealer 2 is a standard stand in basic strategy; the dealer's bust risk is high and hitting risks busting most of the time.

Hard 20 against a dealer 4 is a near-lock; standing maximizes expected value with virtually no risk of busting.

Hard 15 against a dealer 2 is a stand per basic strategy; the dealer's bust probability is high enough that hitting risks more than it gains.

Soft 20 (A-9) is a near-made hand; standing wins against a dealer 10 upcard except when the dealer makes 20 or 21, and no alternative improves expected value.

Hard 20 is a near-unbeatable hand; standing wins the vast majority of the time against a dealer ten, while splitting or doubling would destroy a made hand for no strategic gain.

Hard 10 against a dealer 8 is a standard double per basic strategy; the expected value of doubling exceeds hitting with a strong chance of drawing a 10-value card.

With 11 against a dealer 8, basic strategy favors doubling: one more card gives a strong hand most of the time, and the dealer 8 is not strong enough to justify just hitting for maximum expected value.

Hard 17 against a dealer J is a clear basic-strategy stand; hitting risks busting with minimal upside, and doubling 17 is far too risky.

Hard 13 against a dealer 3 is a standing hand in basic strategy; the dealer has a high bust chance and hitting risks busting.

Hard 15 against a dealer 10 is a losing hand if stood; basic strategy with no surrender available is to hit and try to improve to 17-21.

Hard 20 is a near-certain winner; hitting risks an almost certain bust with no upside.

Hard 20 against a dealer J is a strong standing hand; splitting tens would destroy a near-winning total for negligible gain.
