Blackjack table

Hard 12 against a dealer 10 is a losing stand, and doubling is weak here, so hitting is the best basic-strategy play.

A hard 18 is a stand against the dealer's 10, since busting on a hit is more likely than improving to a winning total.

Hard 13 against a dealer 10 is a losing stand, and doubling is only worthwhile with 9-11, so hitting is the basic-strategy play.

Hard 20 is a strong total that beats most dealer outcomes, and busting on a hit with a dealer Queen showing is too risky. Standing is the correct play.

Hard 12 against a dealer 7 is a weak hand that busts rarely on one card, and standing here leaves the dealer's likely 17-plus too strong, so hitting is the better play.

Hard 17 against a dealer 5 is a stand, since the dealer is likely to bust and doubling on 17 with a 10-value card is not worth the extra risk.

Hard 13 against a dealer King is a losing stand, since the dealer likely makes 17 or better. Hitting is the basic strategy play, and doubling on 13 is not worth the extra risk.

Hard 20 is a strong total that beats most dealer outcomes, and the dealer's 9 upcard gives them a low chance of making 20 or 21, so standing is clearly best.

Hard 15 against dealer 8 is a losing spot, but doubling here is weak; hitting gives the best expected value versus standing on a poor total.

A hard 17 against a dealer 8 is a standing hand, since the dealer's likely total is strong and hitting risks busting on most higher cards.

Hard 18 against a dealer 8 is a strong standing hand, and doubling or hitting risks busting into a likely dealer total of 18 to 21.

Hard 15 against a dealer 9 is a losing stand, and doubling is not favorable here, so hitting gives the best expected value.

Hard 13 against a dealer 8 is a losing stand, and doubling there is not basic strategy, so hitting gives the best expected value.

Splitting aces against a dealer 4 is the standard play, since each ace can become a strong hand and the dealer is weak. Chat is off, so the table message stays empty.

Hard 20 is a strong total that beats most dealer outcomes, and the dealer's upcard of 10 is weak, so standing avoids busting.

Splitting aces is the standard optimal play against a dealer 6, giving two separate hands that each start from an ace. Split aces get one card each, and with the dealer showing a weak upcard this maximizes expected value.

Hard 13 against a dealer 10 is a losing stand, and basic strategy calls for hitting here rather than doubling.

A hard 14 against a dealer 10 is a weak total that busts often if the dealer makes 17 to 21, so hitting is the standard play. The ace is counted as 1, so a hit cannot bust.

A hard 17 against a dealer king is a standard stand, since the dealer busts roughly 23% of the time and hitting risks busting on a card of 10 or higher.

A hand of 5 cannot bust on one card, so hitting is clearly right; doubling with a hard 5 against a dealer 6 wastes the chance to improve a weak total and is not the best use of the double.

A hard 8 is too weak to stand on against a dealer 6, and hitting has no bust risk at this total, so I'm taking a card.

A hard 17 against a dealer 6 is a stand, since the dealer is likely to bust and any hit risks busting my hand.

A total of 20 is a very strong hand, and standing against the dealer's 6 keeps the chance of losing low. Splitting or hitting would only add risk.
