Hard 19 against a dealer 4 is a strong standing hand; hitting or doubling risks turning a likely winner into a loss.

Hard 18 against a dealer 5 is a clear stand; hitting risks busting a strong hand while the dealer is likely to bust from a weak upcard.

Hard 12 against a dealer 10 is a clear basic-strategy hit; standing loses to any dealer draw to 17+, and doubling is not viable at 12.

Hard 14 vs dealer 10 is a hit per basic strategy; standing loses more often than drawing.

Hard 15 vs dealer 10 is close, but standing is the standard basic strategy play; hitting risks busting with only ~23% win chance either way.

Hard 20 is nearly unbeatable; standing maximizes expected value against a dealer 4.

20 is a near-certain winner against a dealer 5; doubling or hitting risks a strong hand for no reason.

Hard 12 against a dealer 5 is a standing situation in basic strategy; the dealer's bust risk is high and hitting risks busting with 12.

Hard 12 vs dealer 9 is a losing standing position; basic strategy calls for a hit since the dealer's strong upcard likely makes a made hand.

Hard 13 against a dealer 9 is a clear basic-strategy hit; standing loses far more often than drawing, and only busting on a 10 improves the dealer's position marginally.

Hard 15 against a dealer 4 is a basic-strategy stand, since the dealer is likely to bust. Doubling with 15 is too risky against a strong upcard.

Hard 20 is nearly unbeatable; standing maximizes expected value against a dealer 8. Doubling or splitting tens would only risk a dominant hand.

Hard 12 against a dealer 9 is a clear hit per basic strategy; standing loses to any dealer 19 draw and only wins if the dealer busts, while hitting risks little given the many 10-value cards that improve the hand.

Hard 13 against a dealer 9 is a clear hit per basic strategy; standing loses against the dealer's likely 19, and only a 10 busts me.

Soft 14 against a dealer 7 is too weak to stand; basic strategy says hit, and doubling is only correct against weak upcards like 5 or 6.

Hard 13 against a dealer 7 is a basic-strategy hit; standing loses to the dealer's likely 17-20, so I need to improve the hand.

With a total of 20 against a dealer 6, standing is clearly optimal — hitting risks an almost certain bust, and the dealer's weak upcard makes 20 a near-certain winner.

Hard 15 vs dealer 5 is a basic-strategy stand; dealer is likely to bust and doubling a stiff hand is negative EV.

Hard 12 against a dealer King is a clear hit per basic strategy; standing loses to any dealer 10-completion, and the bust risk is low enough to justify drawing.

11 against a dealer 6 is a strong doubling spot: only ~1 in 13 draws busts, and the dealer is likely to bust from a 6 upcard. Doubling maximizes expected value versus hitting.

Hard 13 against a dealer 2 is a basic-strategy stand; hitting risks busting with no offsetting dealer bust reduction. Fixed bets make variance avoidance optimal.

Hard 16 against a dealer 10 is a standard hit per basic strategy; standing loses more often than hitting, and doubling is far too risky here.

Hard 19 is a strong made hand; standing is correct against any dealer upcard, especially a 10 (King). Hitting risks busting with no meaningful gain.

Hard 19 is a near-made hand; standing wins most of the time against a dealer 7, while doubling would risk a strong hand for no strategic edge.
