Blackjack table

Hard 13 against a dealer Ace is a losing stand since the dealer's ace often makes 17 or better, so hitting is the standard play. Doubling is not favored here, and I cannot double-check the shoe state.

My hard 14 is a poor stand against a dealer ace, and any card up to a 6 leaves me a small chance to improve, so hitting is the standard play here.

Hard 9 against a dealer 10-card is a strong double-down spot, since a single card often brings a total of 19-21 and the dealer is likely to be strong. Doubling is legal here under the first-two-cards rule.

Hard 16 against a dealer 7 is a losing spot to stand, and doubling is not favorable here, so hitting gives the best expected value.

Hard 20 is a strong total that beats most dealer outcomes, and splitting tens or hitting would only add risk. Standing keeps the bet on a clearly favorable position.

Hard 19 is a strong total against the dealer's King, and any hit risks busting on a 6-deck shoe. Standing keeps the expected loss low.

Hard 20 is a strong total that beats most dealer outcomes, and splitting or doubling a 20 is clearly worse than standing. Dealer shows a 10, so hitting risks busting for little gain.

Soft 15 against a dealer 3 is too weak to double, and standing leaves a poor total, so hitting to improve the hand is the basic-strategy play.

Soft 17 against a dealer 3 is a weak stand, and doubling is not available with three cards, so hitting is the better play.

Hard 13 against a dealer 3 is a basic-strategy stand, since the dealer is weak and busting is likely. Hitting risks busting on a card of 10 or higher.

Hard 15 against a dealer 9 is a losing stand, and doubling is only worthwhile with a stronger total, so hitting gives the best expected value.

Hard 16 against a dealer 10 is a losing stand, and without surrender hitting is the basic-strategy play. Doubling is not favorable here.

Hard 20 is a strong total that beats most dealer outcomes, and the dealer's 7 upcard gives them a weak starting point, so standing is correct. Splitting or hitting would only add risk.

Hard 19 is a strong total that beats most dealer outcomes, and doubling or hitting risks busting against a dealer 5 that often breaks. Standing is the correct play here.

Hard 19 against a dealer 10 is a strong standing hand, and any hit or double risks busting or wastes a favorable position.

Hard 11 against a dealer 7 is a strong doubling spot, since any ten-value card makes 21 and the dealer's 7 is weak. Doubling maximizes expected chips here under the fixed-bet rules.

Hard 15 against a dealer 5 is a basic-strategy stand, since the dealer is likely to bust. Doubling or hitting risks more chips than the modest gain justifies.

A hard 12 against a dealer 10 is a losing stand, and the dealer's strong upcard makes hitting the better play. Basic strategy calls for a hit here.

Hard 19 is a strong total that beats most dealer outcomes, and the dealer shows a 10, so hitting risks busting for little gain.

Hard 17 against a dealer 8 is a stand; doubling here is weak and busting risk on a hit is high.

Holding a pair of queens totaling 20 against a dealer 5 is a strong stand, and splitting or hitting would only add risk. Standing lets the dealer's weak upcard do the work.
