Blackjack table

Hard 12 against dealer's Q is a marginal spot; hitting avoids standing on a weak total where bust risk is low and dealer likely has a strong hand.

Standing on 18 against the dealer's queen is the correct basic strategy play, as hitting risks busting with little chance of improving to a winning hand.

Hard 13 against dealer's Q is a basic strategy stand, but doubling a weak hand is risky; hitting keeps the hand alive and avoids doubling into a likely loss.

Hard 20 against a dealer Queen is a strong standing hand; hitting risks busting with little upside.

With a hard 12 against a dealer 7, hitting is the mathematically correct play; standing loses more in the long run. Doubling is too risky with a weak total.

Standing on 17 against a dealer 5 is the correct basic strategy play; doubling would risk 10 chips for marginal gain on a marginal total.

Standing on 13 against a King avoids busting and is the correct basic strategy play, as the dealer's strong upcard makes hitting risky.

Standing on 19 against the dealer's Jack is the correct basic strategy play; hitting risks busting with little upside.

Hard 12 vs dealer 9 is a weak hand; hitting avoids an immediate loss while doubling risks busting with a weak total. Standing here gives the dealer too much chance to win.

Standing with 18 against a dealer 9 is the correct basic strategy play; hitting risks busting with little gain.

Standing on 18 against a dealer 2 is the correct basic strategy play; doubling would risk turning a strong hand into a weak one.

Standing on 16 against a dealer 3 is the mathematically correct play; hitting risks busting with a high probability of drawing a 10-value card, and doubling is not justified with such a weak total.

Standing with 18 against the dealer's 8 upcard is the correct basic strategy play, as hitting risks busting with little chance of improving to a winning hand.

Standing on 17 is the correct basic strategy play regardless of the dealer's upcard, as hitting risks busting with no realistic chance to improve to a winning total.

Soft 12 (A,A) against dealer Q is a weak hand; doubling locks in a small loss rather than risking a bust on a hit, and I have no table chat to justify a bluff.

I have a hard 20 against the dealer's 10, which is a strong hand; hitting risks busting with little upside, so standing is the optimal play.

Dealer shows a 6, which is a weak upcard. Standing on soft 12 (A,A) avoids busting and lets the dealer likely bust with a weak card.

Soft 14 against a dealer 7 is too weak to stand; hitting preserves the soft total and avoids busting while improving the hand. Doubling is not justified with such a low soft total.

Standing on 14 against a dealer 7 is the mathematically correct basic strategy play to avoid busting and let the dealer potentially bust.

Standing on 13 against a King upcard gives roughly a 40% bust chance if I hit, but standing loses more often in the long run against a high dealer card. Hitting is the mathematically correct play to improve my total.

Hard 14 against dealer K is a classic losing total; standing risks busting to a likely dealer 17+, so hitting is the correct basic-strategy play. Doubling is not allowed here, and splitting is unavailable.

Hard 17 against a King is a classic stand hand; hitting risks busting with little chance to improve to a winning total.

Hard 5 vs dealer 6 is a classic double-down spot; the dealer is weak and doubling maximizes expected value on a favorable hand.
