Blackjack table

Total 11 is a strong doubling hand against a dealer 10 upcard, and doubling maximizes expected value by getting one more card at twice the stake.

I have a strong 20 against a dealer 9; standing maximizes expected value and avoids unnecessary risk.

Total 20 is very strong against a dealer Queen; hitting or doubling risks busting for little gain. Standing maximizes expected value.

Hard 13 against a dealer king is a losing hand if standing, so hitting gives the best chance to improve to 17 or better. Doubling is not advisable with 13 versus a strong upcard.

Hard 13 against a dealer 8 is a hitting hand in basic strategy; doubling is not profitable with this total.

Hard 17 is a made hand and basic strategy says to stand against a dealer 8, since hitting risks busting far more often than it improves the hand.

With a total of 11 against a dealer 8, doubling is the optimal basic strategy play to maximize expected value.

Hard 10 is a strong doubling hand against dealer 7, and doubling maximizes expected value here.

Dealer upcard 5 is a bust card, so standing on 12 maximizes expected value per basic strategy.

Hard 18 is a strong made hand against a dealer 2, and the dealer is more likely to bust or make less than 18, so hitting or doubling risks a good hand unnecessarily.

Hard 14 against a dealer 9 is a losing hand that needs improvement, so hitting gives the best chance to avoid busting while trying to beat the dealer.

Hard 17 is a made hand and hitting risks busting against a dealer 9; standing is the better expected-value play.

Hard 13 is too weak against a dealer Ace; hitting gives a chance to improve while standing likely loses to a made hand. Doubling is not advisable with 13 versus a strong upcard.

Hard 10 vs dealer 6 is a strong double-down spot; dealer is likely to bust and we maximize value with one more card.

Hard 13 against dealer 4 is a stand in basic strategy since the dealer is likely to bust or make a low total.

Hard 14 against a dealer 10 is a losing hand; hitting gives a better chance to improve than standing, and doubling is not profitable here.

Hard 14 against a dealer 8 is a drawing hand; standing gives too little chance to beat the dealer's likely made hand, so hitting is correct.

Total 19 is strong against a dealer 8; hitting risks busting with little upside, so standing is the correct basic strategy play.

Hard 13 is too weak against a dealer 7, which often makes a made hand, so I need to draw to improve.

Hard 14 against a dealer 10 is a losing hand that needs improvement, so hitting gives the best chance to avoid busting while trying to reach a stronger total.

Hard 16 against a dealer 7 is a losing hand, but standing gives the dealer too many chances to make 17 or better, so hitting is the correct play.

Holding 18 against a dealer 7, standing is correct to avoid busting and 18 is a strong hand.

Hard 19 is a strong hand against a dealer 10 upcard; hitting risks busting for little gain, and doubling is not profitable here. Standing is the correct basic strategy play.

Hard 18 beats a dealer 5 upcard often enough; hitting risks busting, and doubling is not appropriate on 18. Standing is the correct basic strategy play.
