Blackjack table

Hard 17 against a dealer 6 is a stand under basic strategy, since the dealer is likely to bust. Hitting or doubling risks busting for little gain.

Hard 18 against a dealer 4 is a stand: the dealer is likely to bust, and doubling or hitting risks more than it gains.

Hard 19 against a dealer king is a strong standing hand, and doubling or hitting only adds risk of busting.

Hard 14 against a dealer 7 is a losing stand, since the dealer likely makes 17 or better, so hitting is the basic-strategy play. Doubling is not worth the extra risk here.

Hard 19 is a strong total that beats most dealer outcomes, and the dealer's 7 upcard makes busting likely for a hit to be risky, so standing is the better play.

Hard 15 against a dealer 10 is a losing stand, and surrender is not allowed, so hitting is the best basic-strategy play. Doubling on 15 is not favorable here.

A hard 18 is a stand against a dealer 10 under basic strategy, since busting on a hit is more likely than improving to a winning total.

A hard 9 against a dealer 3 is a strong doubling spot because the dealer's weak upcard gives a good chance of busting. Doubling takes one extra card for the best expected value.

Hard 6 against a dealer 4 is a clear hit since doubling on 6 is weak and standing cannot win often. Hitting with no bust risk on one card is the best option here.

Hard 16 against a dealer 4 is a stand in basic strategy, since the dealer is likely to bust with a weak upcard. Hitting risks busting on a card of 6 or higher.

A hard 15 against a dealer 8 is a standard hit: the dealer likely makes a strong total, and doubling a 15 here is not worth the extra risk.

Hard 18 is a strong total against the dealer's 8, and any hit risks busting on a card of 8 or higher, so standing is the better play.

Hard 13 against a dealer Ace is a losing stand, and doubling with 13 is weak, so hitting is the basic-strategy play to improve the hand.

Hard 20 is a strong standing total, and the dealer's upcard of 6 is weak, so standing gives a favorable outcome while hitting risks busting.

Soft 18 against a dealer 9 is a weak hold, and basic strategy for this rule set favors hitting here, since the ace lets a hit take the hand to a firm total without busting.

Hard 13 against a dealer 9 is a weak hand that busts often if the dealer makes 19 or better, so hitting is the better play. Any card from a 10 or higher busts, but the other cards keep the hand alive.

Hard 17 against a dealer 9 is a stand, since any hit risks busting on a 10-value card or a hand that still loses to the dealer's likely 19 or 20.

Hard 19 against a dealer 9 is a clear stand; doubling or hitting would risk more than it gains.

Hard 12 against a dealer 7 is a hit under basic strategy, since standing on 12 loses to the dealer's likely 17-21 and doubling a hard 12 is not favorable.

Hard 15 against a dealer 7 is a losing stand, since the dealer likely makes 17 or better, so hitting gives the best expected value under basic strategy.

Hard 13 against a dealer 6 is a basic-strategy stand, since the dealer is likely to bust. Doubling or hitting here risks more chips than it gains.

Hard 13 against a dealer 3 is a basic-strategy stand because the dealer is likely to bust, and hitting risks busting on a high card. Doubling with 13 is not worth the extra exposure here.

Hard 19 against a dealer King is a strong standing hand; hitting or doubling risks busting for little gain.

Hard 20 is a strong total that beats most dealer outcomes, and the dealer's ten upcard gives a high bust chance, so standing is clearly best.

A hard 16 against a dealer 8 is a losing stand, and basic strategy calls for hitting. Doubling is not favorable with 16, so I'll take another card.

A hard 17 against a dealer king is a stand under basic strategy, since the dealer's likely total of 20 makes hitting a losing play and doubling is not favorable.
