Blackjack table

Hard 16 against a dealer 7 is a basic-strategy hit; standing loses more often than drawing since the dealer's 7 upcard frequently makes 17 or better.

Hard 18 against a dealer 7 is a clear stand; hitting risks busting a made hand that already beats most dealer outcomes.

With double-after-split allowed, basic strategy says split 2s against a dealer 7; two weak starting hands become better hitting opportunities than a hard 4.

Hard 5 vs dealer 7 is far too weak to stand; standing only wins on a dealer bust, so I take a card and reevaluate. Doubling is not justified at total 5.

Hard 10 against a dealer 7 is a hit per basic strategy; doubling is unavailable on this multi-card split hand, and standing on 10 gives up expected value.

Hard 17 vs dealer 7; standing is correct since hitting risks busting for little gain.

Hard 12 against a dealer 7 is a clear basic-strategy hit; standing leaves the hand too weak against a likely dealer 17-20, and doubling with 12 is not viable.

Hard 15 against a dealer 7 is a clear basic-strategy hit; standing loses to any dealer 17+ and the dealer is more likely to make a hand than bust.

Hard 11 against a dealer 10 is a standard double-down in 6-deck basic strategy; maximizing value on the most favorable drawing total.

Hard 20 against a dealer King is nearly unbeatable; standing maximizes expected value and avoids any risk of busting.

Never split fives; hard 10 against a dealer 4 is a strong double per basic strategy, maximizing EV with the dealer likely to bust.

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

Hard 15 against a dealer 4 is a stand per basic strategy; the dealer's bust probability is high and hitting risks busting with 12-value cards.

With double-after-split allowed, basic strategy says split 3,3 against a dealer 2; building two hands starting at 3 beats hitting into a weak total of 6.

Hard 8 (3+5) vs dealer 2 is a basic-strategy hit; doubling an 8 against a weak upcard is still negative EV compared to drawing.

Hard 14 against a dealer 2 upcard: basic strategy says stand, since the dealer's bust probability is high and hitting risks busting. I'll keep hand 1 (soft 14) for later action.

Soft 14 (A-3) against a dealer 2 is too weak to stand or double; basic strategy says hit to try to improve to a made hand.

Hard 14 against a dealer 2 is a standing play in basic strategy since the dealer's bust probability is high with a low upcard.

Hard 8 versus a dealer 8 is a clear hit per basic strategy; doubling is unfavorable and standing leaves the likely weaker total.

Hard 15 against a dealer 8 is a basic-strategy hit; standing risks losing to the dealer's likely 18, and only a bust on 10 or higher hurts.

Hard 18 vs dealer 8 is a clear stand; hitting risks busting for minimal gain.

Hard 16 against a dealer 3 is a standing situation per basic strategy; the dealer's bust risk is high and hitting risks busting with 10-value cards abundant.

Hard 7 vs dealer 9 is a clear hit; doubling is too aggressive against a strong upcard.

Hard 16 against a dealer 9 is a losing standing position; basic strategy calls for a hit since the dealer's likely made hand beats 16.

Hard 17 against a dealer 9 is a stand in basic strategy; hitting risks busting (~69%) with little gain since 17 already beats many dealer outcomes.

Soft 16 (A-5) against a dealer 2 is a standard hit; doubling is only correct against dealer 3-6, and standing leaves a weak total.

Soft 18 vs dealer 10 is a losing standing position; basic strategy says hit to try for 19-21, with A7 able to absorb a bad card.

Hard 18 against a dealer 10 is a clear stand; hitting risks busting with little upside since only 2-3 improve the hand.

Hard 17 against a dealer 5 is a clear stand; hitting risks busting while the dealer is likely to bust from the 5 upcard.

Hard 16 against a dealer 4 is a standing play per basic strategy; the dealer's bust probability is high and hitting risks busting with 10-value cards abundant.

Hard 17 against a dealer 10 is a standing hand in basic strategy; hitting risks busting with no meaningful gain since only 2-4 improve without high bust risk.

Hard 12 vs a dealer 10 is a losing total; basic strategy says hit (standing only wins if the dealer busts, and 12 can't bust with one card). Doubling would just stake more on a negative-EV spot.

Hard 8 against a dealer 5 is too weak to stand and not a standard double; hitting is correct to build toward a strong total while the dealer has a bust-prone upcard.

Soft 19 is a strong made hand; basic strategy stands against a dealer 5, and doubling is not legal here anyway.
