Blackjack table

Hard 18 against a dealer 5 is a strong stand, since the dealer is likely to bust and hitting risks busting my hand. Doubling is not worth the extra exposure here.

Hard 14 against a dealer 2 is a hit under basic strategy; doubling is only worthwhile with 10 or 11, and standing on 14 loses to most dealer outcomes.

Hard 13 against a dealer 8 is a losing stand, and basic strategy calls for hitting since the dealer likely makes 18 or better. Doubling is not worthwhile here.

A hard 18 against a dealer 2 is a strong stand, since the dealer's weak upcard gives a good chance of busting and doubling would add risk for little gain.

Hard 14 against a dealer 6 is a stand under basic strategy, since the dealer is likely to bust and hitting risks busting my hand. Doubling is not worth it with a total this weak.

Hard 15 against a dealer 10 is a losing stand, and doubling is not favorable with no surrender available, so hitting is the best option.

Hard 14 against a dealer 4 is a stand under basic strategy, since the dealer's weak upcard gives a good chance of busting and hitting would likely bust my hand.

A hard 17 is a stand against a dealer 10-up, since the dealer's likely total is 17-21 and hitting risks busting on most draws.

Hard 14 against a dealer 5 is a stand under basic strategy, since the dealer is likely to bust. Doubling here risks too much on a hand that is weak but not strong enough to press.

Hard 15 against a dealer 7 is a losing stand, and doubling is not favorable, so hitting is the standard basic-strategy play.

Hard 12 against a dealer 2 is a hit under basic strategy, since the dealer's weak upcard does not justify standing on 12 and doubling is not favorable here.

Hard 17 against a dealer 2 is a stand, since the dealer's weak upcard gives a good chance of busting and any hit risks busting my hand.

Hard 18 against a dealer Jack is a stand under basic strategy, since the dealer is likely to make 20 or bust only after a stiff. Doubling or hitting here adds more risk than it gains.

Hard 10 against a dealer 5 is a strong doubling spot since the dealer is likely to bust; doubling one card maximizes expected value here.

Hard 13 against a dealer 10 is a losing stand, so basic strategy favors hitting over standing or doubling.

Hard 10 against a dealer 6 is a strong doubling spot in basic strategy, since the dealer is likely to bust and one card can bring the hand to a strong total. Doubling takes advantage of this edge.

Hard 19 against a dealer 10 is a strong standing hand, and hitting or doubling risks busting for little gain. Standing is the correct basic strategy play.

A hard 8 against a dealer 9 is a weak total that can't stand, and doubling on 8 is too weak to justify the extra risk, so hitting is the best option.

A hard 17 against a dealer 9 is a losing stand, and the dealer's likely strong total makes hitting the better option despite the bust risk.

Hard 10 against a dealer 10 is a hit under basic strategy, since doubling only pays off against dealer 2 through 9. Hitting gives a better expected result than doubling or standing here.

A hard 12 against a dealer 10 is a losing stand, and drawing one card has a better expectation than standing on 12 here.

Hard 20 is a strong total that beats most dealer outcomes, and the dealer's 6 upcard is weak, so standing is clearly best rather than risking a hit.
