Blackjack table

Standing on 15 against a dealer 3 is the mathematically correct play; hitting risks busting on a 7 or higher, which is more than half the deck, while doubling would be reckless with a weak total.

Standing with 18 against a dealer King is the correct basic strategy play, as hitting risks busting with little chance of improvement.

Soft 16 vs dealer 3 is too weak to stand; hitting preserves the ace as a flexible 11 and avoids busting on the next card, while doubling is not justified with such a low total.

I have a soft 19 (A-5-3), which is a strong hand. Standing avoids the risk of busting and is the correct basic strategy play against a dealer 3.

Hard 12 vs dealer Q is a weak hand; standing loses to any dealer 17+ which is likely with a Q upcard. Hitting is the correct basic strategy play to improve.

My hand totals 19, which is a strong standing total against the dealer's Queen upcard. Hitting risks busting with little upside, so standing is the clear play.

Hard 11 against dealer's 8 is a classic double-down spot; I have a high probability of drawing a 10-value card to make 21, and doubling maximizes expected value on this strong starting total.

Soft 20 is a very strong hand; standing avoids the risk of busting while the dealer's 8 upcard is unlikely to beat it.

Soft 13 against a dealer 6: doubling is risky because a weak card (2-6) leaves a marginal total, so I hit to preserve the soft flexibility and improve to a stronger hand.

Soft 18 against a dealer 6 is a strong standing position; hitting risks turning a favorable hand into a weak or busted one.

Standing on 15 against a dealer 6 is the correct basic strategy play, as the dealer is in a weak position and likely to bust. Doubling would risk 10 extra chips with a low probability of winning.

Standing on 19 against an Ace is the correct basic strategy play; hitting risks busting with little gain, and doubling is not advisable with a stiff total against an Ace.

With a hard 5 against a dealer 8, doubling maximizes expected value since I'm likely to improve to a strong total on the next card, and the 3:2 blackjack payout makes doubling on weak starting hands profitable in this 6-deck game.

Hard 20 is a very strong hand; standing maximizes expected value against a dealer 7 upcard and avoids the risk of busting.

With a hard 13 against the dealer's 5, hitting is the basic-strategy play to avoid standing on a weak total that is likely to lose. Doubling is not recommended here since the risk of busting outweighs the potential gain.

Soft 13 vs dealer 9 is too weak to double; hitting preserves the soft total and avoids busting while keeping the option to improve to a strong hand.

Soft 17 against a dealer 9 is too weak to hit profitably; standing minimizes expected loss since hitting risks busting or ending with a total that still loses to the dealer's likely 19+.

Hard 5 vs dealer 9 is a clear hit; doubling would be a severe mistake since I'm almost certainly behind and need to improve to 17+ or avoid busting with a low card.

Standing on 15 against a 9 upcard minimizes expected loss since hitting risks busting with a high card, and doubling is not allowed.

Standing on 17 against the dealer's Queen avoids the high risk of busting by hitting, and doubling is unattractive since I'm unlikely to improve to a strong total.

Hard 13 vs dealer 2 is a weak hand; hitting is the standard play to try to improve, and doubling a 13 is too risky.

Standing on 18 against a dealer 2 is the correct basic strategy play; hitting risks busting with little gain.

Standing on 17 is correct because hitting risks busting with no realistic path to a strong total, and doubling would be reckless against a 10 upcard.

Hard 12 vs dealer 3 is a marginal standing spot, but basic strategy favors hitting to avoid busting on a 10-value card; doubling is not clearly profitable here.
