Hard 17 vs dealer 6 is a clear stand; hitting risks busting with little gain.

18 vs dealer 4 is a clear stand; hitting risks busting for little gain.

Hard 19 vs dealer 10 is a clear stand; hitting or doubling risks a strong hand for negligible gain.

14 vs dealer 7 is a basic-strategy hit; standing loses more often than drawing one card.

Hard 19 vs dealer 7 is a clear stand; hitting risks busting for negligible gain.

Hard 15 vs dealer 10 is a losing hand; basic strategy says hit since standing loses more often than drawing.

Hard 18 vs dealer 10 is a stand per basic strategy; hitting risks busting for little gain.

Hard 9 vs dealer 3 is a hit; doubling 9 vs 3 is not profitable.

Hard 16 vs dealer 3 is a marginal spot, but basic strategy favors hitting since standing gives ~38% win vs dealer's likely 13+ draw; hitting improves expected value slightly.

Hard 18 vs dealer 3 is a clear stand; hitting risks busting for minimal gain.

Hard 6 vs dealer 4 is far too low to stand; hitting is standard, and doubling is not justified on a 6.

16 against a dealer 4 is normally a stand, but this is a three-card 16 (2-4-K) so the composition shifts the marginal play toward hitting; with only hit/stand legal, hitting slightly improves EV.

Hard 15 vs dealer 8 is a losing standing position; basic strategy says hit.

Hard 18 vs dealer 8 is a clear stand; hitting risks busting with little gain.

Hard 13 against an ace is a losing standing hand; basic strategy says hit.

Hard 20 against a dealer 6 is a near-lock; standing maximizes expected value. Doubling or hitting only risks ruining a winning hand.

Soft 18 vs dealer 9 is close, but standing is the safer standard play; hitting soft 18 vs 9 is only marginally better and doubling is worse.

Hard 14 against an ace is a losing hand; basic strategy says hit since dealer peeking removes blackjack risk but the ace still likely makes 17+.

Soft 18 vs dealer 10 is a marginal hand; basic strategy says stand (hitting only slightly better in some counts, but standing is the safe standard play).

Hard 10 vs dealer 7 is a clear hit; doubling is only correct against dealer 2-9 in basic strategy... actually 10 doubles vs 2-9, but with 6-4 vs 7 doubling is standard too. However, hitting is safe and near-equivalent; I'll take the free card.

Hard 16 vs dealer 7 is a hit by basic strategy; standing loses more often than drawing.

Splitting 3s against a dealer 5 is basic strategy; the weak 6 total gains far more from two hands against a bust-prone dealer upcard.

Pair of 3s vs dealer 5: basic strategy says split, but with a 3-3 already split hand showing 6, hitting is standard for 6 vs 5 when re-splitting isn't ideal; actually 6 vs 5 is a hit per strategy since DAS split of 3s was taken already. Hitting 6 against 5 is the correct play here.

Hard 16 against a dealer 5 is a standard stand; dealer bust risk is high and hitting loses more often.

13 vs dealer 5 is a standard stand; dealer bust frequency is high with a 5 upcard.

Hard 19 vs dealer 10 is a clear stand; hitting or doubling risks a strong hand for no edge.

Hard 12 vs dealer K is a hit per basic strategy (only stands vs 4-6).

Hard 18 against a dealer king is a losing hand on average, but hitting risks busting; standing gives the best expected value since only 3-6 improve the hand while many cards bust it.

Hard 18 vs dealer 10 is a stand per basic strategy; hitting risks busting for minimal gain.

Hard 17 against a dealer 10 is a losing stand; basic strategy calls for a hit since the dealer's expected total beats 17 more often than not.
