Blackjack table

Hard 7 versus a dealer jack is a clear hit; standing or doubling would be far too weak against a ten.

Hard 15 against a dealer 10 is a hit in basic strategy: standing loses to most dealer totals, and drawing still has a reasonable chance to improve without a double or surrender option.

A pair of aces should always be split, including against a dealer 2, because each ace starts a strong new hand.

Hard 13 against a dealer 5 is a basic-strategy stand: the dealer is weak and likely to bust, so hitting risks busting a made hand.

Pair of 3s totals 6 against a dealer 8. With DAS, basic strategy splits 3s only versus 2–7 and hits versus 8, so hitting is correct.

Hard 14 against a dealer 8 is a hit under basic strategy, since standing loses too often when the dealer makes a hand.

Hard 20 against a dealer 8 is a clear stand; hitting risks busting a strong made hand.

Hard 13 versus dealer 6 is a basic-strategy stand; the dealer is likely to bust, so hitting or doubling risks a worse outcome.

Hard 14 against a dealer 10 is a clear hit in basic strategy; standing loses too often and doubling is not justified.

Hard 17 versus a dealer 9 is a clear stand; hitting or doubling risks busting a made hand.

Hard 14 versus a dealer 5 is a basic-strategy stand: the dealer is weak and likely to bust, so hitting risks busting a made hand.

Hard 15 against a dealer 9 is a hit in basic strategy; doubling would add risk on a weak total that often loses even if it improves.

Hard 20 against a dealer 9 is a clear stand; hitting risks busting and only an ace improves the hand.

Hard 15 versus a dealer 8 is a hit under basic strategy; standing loses too often and doubling is not justified.

Hard 20 is a strong made hand against a dealer 8, and hitting risks busting on almost every card. Standing is the clear basic-strategy play.

Hard 20 is already a winning total against a dealer 2, so standing avoids busting and keeps the strong hand.

Hard 20 against a dealer 2 is already a winning hand almost always; hitting or doubling risks a bust and splitting tens gives up a made 20.

Hard 12 against a dealer 10 loses if I stand whenever the dealer makes a hand, so I hit rather than double.

Hard 17 versus a dealer 10 is a clear stand; hitting risks busting and is worse than letting the dealer play.

Hard 19 versus a dealer 6 is a strong made hand; standing is the clear basic-strategy play, while hitting or doubling risks a bust for little gain.

Soft 13 versus a dealer 6 is a standard double: the weak upcard favors taking one more card for maximum value.

Hard 20 versus a dealer king is a made hand; hitting or doubling risks busting a near-certain winner, and splitting tens is negative EV.

Hard 17 against a dealer 7 is a clear stand: hitting busts on most cards and doubling only adds risk to a made hand.

Hard 16 versus a dealer 6 is a basic-strategy stand: the dealer is likely to bust, and hitting or doubling a stiff total is a negative-EV deviation.

Soft 17 versus a dealer 8 is a hit in basic strategy; doubling is only correct against weaker upcards, and standing leaves too much equity on the table.

Hard 17 against a dealer 8 is a clear stand; hitting risks busting a made hand.
