Blackjack table

A hard 9 against a dealer 3 is a strong doubling spot, since the dealer is likely to bust and one extra card is a good expected gain. Doubling is legal on any first two cards.

Hard 16 against a dealer 7 is a losing stand, and the dealer's likely 17-plus makes hitting the better option. Doubling is not worth the extra risk here.

Hard 17 against a dealer 2 is a stand under basic strategy, since the dealer is likely to make a weak total and busting the 17 with a hit is the bigger risk.

Hard 20 is a strong total that beats most dealer outcomes, and the dealer's Js upcard gives little reason to take risk. Standing preserves the hand against a likely dealer 20 or 19.

A pair of tens totals 20, which beats most dealer outcomes; splitting or hitting risks busting a strong hand against a dealer 9.

Hard 16 against a dealer king is a losing stand, and doubling is not favorable here, so hitting is the basic-strategy play.

Hard 18 against a dealer king is a stand, since the dealer's likely total of 20 beats most hands and hitting risks busting on a 10-value card.

Hard 15 against a dealer 10 is a losing stand, and doubling is unprofitable with a 15, so hitting is the basic strategy play here.

A hard 17 is a stand against a dealer 10, since the dealer must hit soft 17 and busting the hand with a hit is a larger risk.

Soft 17 against a dealer 10 is a hit in basic strategy, since doubling soft 17 is only profitable against dealer 3 through 6. Hitting gives a better expected result than standing on 17 here.

Soft 18 against a dealer 10 is a losing stand, and hitting is the basic-strategy play here since the hand can improve without busting on one card. Doubling is not legal in this observation.

Soft 20 is already a strong total against a dealer jack, and hitting risks breaking a hand that is likely to win more often than not.

Soft 15 against a dealer 7 is a weak doubling spot, so hitting keeps the ace flexible and improves the hand without overcommitting the bet.

A hard 15 against a dealer 7 is a losing stand, so basic strategy favors hitting to improve the hand.

Two tens total 20, which beats almost any dealer result and busting on a hit is too likely. Splitting or doubling is worse than standing here.

A hard 5 is too weak to stand on and doubling only pays with a strong total, so hitting is the basic-strategy play against the dealer's 6.

Hard 7 against a dealer 6 is an easy hit since standing loses to most dealer outcomes, and any card from the shoe is unlikely to bust a 7.

A hard 17 against a dealer 6 is a standing hand, since the dealer's weak upcard makes busting likely and hitting 17 risks a bust on most draws.

Hard 20 is a strong total that beats most dealer outcomes, and the dealer's 4 upcard is weak, so standing avoids busting.

Hard 12 against a dealer 5 is a basic-strategy stand, since the dealer is likely to bust and hitting a 12 risks busting on the next card.

Twenty is a very strong total against a dealer 9, and splitting or hitting would only add risk of busting.

A hard 10 against a dealer 5 is a strong double-down spot, since the dealer is likely to bust and one extra card has a good chance of making 19-21.

A hard 9 against a dealer 3 is a strong double-down spot, since the dealer's weak upcard gives this hand a good chance to win with one extra card. Doubling also keeps the expected value high relative to hitting or standing.

Hard 12 against a dealer 3 is a hit under basic strategy, since standing only becomes correct against dealer 4 through 6. Taking a card avoids a weak standing total.

A hard 17 against a dealer 3 upcard is a stand in basic strategy, since the dealer is likely to bust. Hitting would risk busting on most draws.

Hard 20 is a strong total that beats most dealer outcomes, and the dealer's 7 upcard gives them a weak-to-average chance to finish above 20, so standing is clearly best.
