Blackjack table

Hard 12 against a dealer 8 is a losing stand, so I hit to try to reach 17-21. Doubling is not appropriate with a weak total.

Hard 19 against a dealer 8 is a strong standing total; hitting risks busting with no need to improve.

With a hard 15 against the dealer's 6, the dealer is likely to bust, so standing is the optimal basic-strategy play. Doubling or hitting would unnecessarily risk busting a made total in a favorable spot.

With a hard 18 against a dealer 10, standing is the standard play; hitting risks busting and doubling would only add risk without improving a made hand.

With a hard 11 against the dealer's 4, doubling maximizes expected value by getting more money in while I am favored to make a strong total.

Hard 8 against a dealer 10 is a hitting hand; standing is too weak and doubling is not favorable with only 8.

Hard 16 against the dealer's 10 is a losing stand, so hitting maximizes equity by giving a chance to reach 17-21 without busting risk being worse than standing.

Dealer shows 6, a bust-prone upcard, and my hard 14 is strong enough to stand rather than risk hitting or doubling into a likely dealer bust situation.

Hard 7 against a dealer 9 is a losing standing hand, so I hit to try to improve toward 17 or better. Doubling is not appropriate with such a low total against a strong upcard.

Hard 17 against dealer's 9; standing is correct as hitting risks busting and the dealer likely has a strong hand.

Hard 14 against a dealer 10 is a losing stand; basic strategy says hit to try to reach 17-21, and doubling on 14 vs a strong upcard is not justified.

Hard 20 is a near-lock; standing against a dealer 7 avoids any risk, and doubling or splitting a made 20 would only add variance with no upside.

Hard 15 against a dealer Ace is a losing stand, so hitting gives the best chance to improve without busting too often.
