Blackjack table

Standing on 14 against a Jack upcard avoids busting and is the statistically correct play; doubling would risk 10 chips on a weak total.

Standing on 17 against a dealer 6 is correct basic strategy; hitting risks busting with no gain, and doubling is unfavorable on a stiff 17.

Standing on 13 against a 3 avoids busting and lets the dealer's weak upcard potentially bust on its own; doubling is too risky with a stiff hand.

With a hard 5 against a dealer 2, doubling would be risky since I'm likely to bust on a high card; hitting gives me a chance to improve to a playable total without committing extra chips on a weak starting hand.

Hard 7 against dealer's 2 is a weak hand; hitting is the correct basic strategy play to improve to a standing total.

Hard 12 vs dealer 2 is a marginal stand, but hitting keeps the bust risk low and avoids a weak standing total against a potentially strong dealer hand.

Standing on 16 vs dealer 2 minimizes expected loss since hitting risks busting with a high card, and the dealer's weak upcard doesn't justify the bust risk.

Hard 20 against a dealer 7 is a strong standing hand; hitting risks busting with little gain, and doubling is not advisable with a made hand this strong.

Standing on 19 against the dealer's 10 is the correct basic strategy play; hitting risks busting with little gain, and doubling would be reckless.

Standing on 19 against a Jack upcard is the correct basic strategy play; hitting risks busting with little gain.

Standing on 14 vs dealer J avoids busting with a weak hand; doubling is too risky here.

Standing on a hard 17 against a dealer 2 is the mathematically sound play; hitting risks busting with little gain since the dealer is likely to make a hand.

Standing on 20 against a dealer Queen is the correct basic strategy play; hitting risks busting with little upside.

Standing on 15 against a dealer 6 is the correct basic strategy play; the dealer is in a weak position and hitting risks busting with a 50% chance on a 10-value card.

Standing on 15 against a dealer 5 is the correct basic-strategy play; doubling a hard 15 is not recommended. The dealer's weak upcard makes standing the safer option.

Soft 16 against a dealer King is a weak hand, but doubling is allowed on the first two cards and I have enough bankroll. I'll take one card to try to improve to a strong total while risking only one extra bet.

Splitting 2s against an 8 is the mathematically correct play in a 6-deck game, as it avoids playing a weak 4 as one hand and gives two chances to improve with doubles available after the split.

Hand totals 6, which is very weak; hitting is the only reasonable play to improve the hand. Doubling would risk 10 chips on a terrible total against an 8 upcard.

Hard 16 against dealer's 8 is a marginal spot, but hitting risks busting with a 10-value card still likely in the shoe; standing preserves the bankroll.

Soft 13 vs dealer 8: doubling is the basic-strategy play because the soft total can absorb a hit without busting, and the dealer's weak upcard makes standing less attractive. Doubling captures favorable EV on the first two cards.

Hard 19 against a dealer 2 is a strong standing hand; hitting risks busting with little gain, and doubling is not advisable on a hard 19.

Hard 7 against dealer's 8 is a clear hit; doubling would be reckless with such a weak total, and standing gives the dealer a strong chance to improve.

My hard 17 against the dealer's 8 is a marginal but correct stand; hitting risks busting with little chance to improve to a winning total.

Hard 13 against dealer 4 is a classic hit/stand borderline; basic strategy leans stand, but with a small bankroll and no insurance, taking one more card to try to improve to 17+ is reasonable. I'll hit to avoid standing on a weak total.

Standing on 14 against a dealer 3 is too risky; hitting gives a chance to improve to 17–21 without busting immediately, and doubling is not justified with a weak 14.

Standing on 15 against a 3 avoids busting and lets the dealer's weak upcard potentially bust on its own. Hitting risks a high card and is not worth the small gain.

Standing on 16 against a dealer 5 is the mathematically correct basic strategy play, as the dealer's weak upcard makes busting more likely than improving my hand.
