Blackjack table

Hard 20 against a dealer king is a strong hand that beats most dealer outcomes, and splitting or doubling is not appropriate here, so standing is the correct play.

Hard 12 against a dealer 5 is a stand under basic strategy, since the dealer is likely to bust and hitting risks busting my hand.

Hard 17 against a dealer 4 is a stand under basic strategy, since the dealer is likely to bust and doubling or hitting adds more risk than reward.

A hard 10 against a dealer 7 is a strong doubling spot, and the dealer stands on soft 17, so doubling the bet is the highest-expectation play.

Hard 7 against a dealer 10 is too weak to stand, and doubling on 7 gains little, so I'll take a card to improve the hand.

A hard 17 against a dealer 10 is a stand: the dealer's likely made hand is strong, and any hit risks busting on a 10-value card.

A hard 6 against a dealer 10 is too weak to stand and too low to double profitably, so hitting gives the best expected value.

A hard 9 against a dealer queen is a weak stand, and hitting has no bust risk since any card up to 10 keeps the hand live, so hitting is the better play.

A hard 19 is a strong total against the dealer's 10-value upcard, and hitting risks busting on most of the remaining cards.

Hard 17 against a dealer jack is a stand under basic strategy, since the dealer's likely 20 or 17 makes doubling or hitting a poor expected value.

Hard 12 against a dealer 3 is a basic-strategy stand, since the dealer's weak upcard gives them a high bust chance and hitting risks busting. Chat is off, so the table message stays empty.

Hard 16 against a dealer Ace is a losing spot whether I stand or double, and surrender is not available, so hitting is the standard best play. Dealer hits soft 17 here, which slightly favors the dealer, but hitting still gives the best expected value.

Hard 13 against a dealer 6 is a stand under basic strategy, since the dealer's weak upcard gives the hand a decent chance to win without taking a card that is likely to bust.

A hard 6 against a dealer 8 is a weak total that busts rarely to hit, and the 3-3 split is not favored against an 8 under these rules. Hitting is the standard play here.

A hard 14 against a dealer 8 is a weak total, but standing relies on the dealer making 18 or better, which is common. Hitting gives a better expected outcome than standing here, and the bust risk on one card is acceptable.

Pair of sixes against a dealer Jack is a hit under basic strategy, since splitting 6s only pays against dealer 2 through 6. Hitting 12 is the better play here.

Hard 20 is a strong total that beats most dealer outcomes, and the dealer's Queen upcard gives a weak chance of improving past it, so standing is clearly best.

Hard 12 against a dealer 6 is a stand under basic strategy, since the dealer must hit weak totals and busts often. Doubling or hitting would risk busting the hand.

Hard 9 against a dealer 6 is a strong doubling spot, since the dealer is likely to bust and one card is enough to make a good total.
