Blackjack table

Standing on 19 against the dealer's Queen is the correct basic strategy play; hitting risks busting with little chance of improving to a winning hand.

Hard 9 vs dealer J is a clear hit; doubling would be risky with a high upcard and no blackjack possible.

Standing on 15 against a Jack is a losing play; hitting gives a chance to improve to 17-21, and the dealer likely has a 10-value hole card.

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

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

Standing on 17 against a dealer 6 is the correct basic strategy play; the dealer is likely to bust with a weak upcard, and hitting risks improving to a marginal total while exposing me to a bust.

Hard 20 against a dealer 6 is a strong standing hand; hitting risks busting with little gain, and doubling a 20 is not advisable.

Standing on 20 against a dealer 7 upcard is a strong play; the dealer is unlikely to beat 20 and hitting risks busting.

Hard 11 is the strongest doubling candidate; dealer's King upcard is weak and unlikely to improve enough to beat 11 plus one card. Doubling locks in the bet and maximizes expected value on this favorable spot.

Soft 17 against a dealer 9 is a borderline hand; standing avoids busting and lets the dealer risk busting with a weak upcard, which is the safer play here.

Standing on 20 against the dealer's Ten is the correct basic strategy play; hitting risks busting with no realistic chance to improve to a winning hand.

Standing on 17 against a Queen is the correct basic strategy play; hitting risks busting with no realistic chance to improve to a winning hand.

Standing with 15 against an 8 upcard minimizes the risk of busting on a hit, since the dealer is likely to end with a moderate or weak total.

Hard 12 vs dealer 3 is a marginal stand, but doubling a weak 12 is risky; hitting keeps me alive and avoids busting with a stiff hand.

Standing with a hard 18 against the dealer's 3 is the correct basic strategy play, as hitting risks busting with little gain.

Standing on 15 against a dealer 4 is the correct basic strategy play, as the dealer is in a weak position and hitting risks busting with a high probability.

Hard 20 against an Ace upcard is a strong hand; standing avoids busting and lets the dealer risk busting on the hole card.

With a hard 6 against a dealer 7, doubling is risky and standing loses. Hitting keeps the hand alive and gives a chance to improve to a playable total.

Soft 17 against a dealer 7 is a marginal spot, but hitting risks busting the soft hand with little gain; standing is the safer play.

With a hard 14 against the dealer's J, hitting risks busting more often than it improves the hand; standing is the mathematically sound basic-strategy play.

Hard 14 against dealer's 10 is a basic-strategy stand candidate, but with 5 decks remaining and a fresh shoe, hitting to avoid a likely dealer 20 is slightly preferred; doubling a weak 14 is too risky.

Hard 20 against a dealer 7 is a strong hand; hitting risks busting with little gain, and doubling is not advisable with such a high total.

Standing on 14 against a queen is a losing play; hitting gives a chance to improve to 17+ despite the bust risk. Doubling is too risky with a stiff 14.
