Blackjack table

I have a soft 19 (A+8) against the dealer's Queen. Standing is the optimal play since hitting risks busting or only marginally improving, and doubling would be reckless with a weak upcard.

Standing on 15 vs dealer 3 avoids busting and lets the dealer risk busting with a weak upcard; doubling is too risky with a high bust chance.

Standing on 14 against a dealer Ten is the mathematically correct basic strategy play to minimize expected loss, as hitting risks busting more often than it improves the hand.

Hard 11 against dealer Ace is a strong doubling spot; 6-deck S17 basic strategy doubles 11 vs A, and doubling maximizes expected value on a near-guaranteed improvement to 17+.

Standing on 17 against a dealer 5 is the correct basic strategy play; hitting risks busting with only a 32% chance of improving to 18-21.

My hand totals 19, which is strong against the dealer's 2. Standing avoids the risk of busting and lets the dealer likely bust with a weak upcard.

I have a hard 20 against the dealer's 4, which is a strong position; standing maximizes my chance to win without risking a bust.

Hard 5 is a terrible hand; standing loses almost always. Doubling is risky with only 5, so hitting maximizes the chance to improve before deciding.

Hard 15 vs dealer Q is a losing hand; standing minimizes expected loss since hitting busts ~54% of the time with no double option available.

Hard 12 vs dealer 9 is a losing hand either way, but hitting reduces the bust risk compared to standing and gives a chance to improve to 17-19. Doubling is not justified with only 33% chance of making a strong hand.

Hard 12 vs dealer 6 is a marginal stand in basic strategy, but with a 2 showing I prefer to hit to improve my total and avoid standing on a weak hand.

Standing on 18 against a dealer 6 is the correct basic strategy play, as the dealer is likely to bust with a weak upcard.

Standing on 16 against a 10 is the least bad option; hitting risks busting over 60% of the time and doubling is too risky with a weak total.

Standing on 13 against a dealer J is the correct basic strategy play to avoid busting with a weak hand.

Soft 18 against an Ace upcard is a solid standing hand; doubling would risk turning a strong soft total into a weaker one, and hitting offers little upside while increasing bust risk.

With a hard 10 against the dealer's 2, doubling is the mathematically correct play to maximize expected value, as the dealer is unlikely to bust and I have a strong drawing chance.

Standing on 20 against a dealer 5 is the optimal play; hitting risks busting with little gain, and doubling is not advisable on a hard 20.

Standing on 15 against a dealer 3 is the correct basic strategy play; hitting risks busting with a 68% chance, and doubling is not advisable with a stiff hand.

Hard 20 against an Ace is a strong hand; standing avoids the high risk of busting and lets the dealer's potential blackjack resolve naturally.

Standing with a hard 19 against an Ace upcard minimizes the risk of busting while still having a strong chance to win or push.
