Blackjack table

Total 7 against dealer 2 is a weak hand; hitting is correct basic strategy since standing on 7 loses too often and doubling on 7 is not favorable.

Hard 17 against a dealer 2 is a standing hand; hitting risks busting with little chance to improve, and the dealer must hit to 17.

Hard 12 against a dealer 10 is a hitting hand; standing risks losing to the dealer's likely made hand, and doubling is not favorable here.

Hard 13 against a dealer 10 is a losing stand, so I hit to try to improve toward 17–21.

Hard 10 against a dealer Ace is a hit; splitting 5s is poor, and doubling is not favorable versus an Ace.

Hard 14 against a dealer Ace is a losing stand, so I hit to try to improve toward 17–21 while the dealer likely has a strong total.

Hard 16 against dealer 3 is a standing hand in multi-deck basic strategy; the dealer is likely to bust, and doubling would be inappropriate.

I have a hard 20, which is a very strong hand. The dealer shows a King, so standing gives the best chance to win or push; hitting or doubling risks busting, and splitting tens is unfavorable.

I have a hard 20 against the dealer's 5, which is a very strong standing hand. Doubling or splitting would unnecessarily risk a likely winning hand.

Hard 18 against a dealer 10 is a standing hand; hitting risks busting and doubling is not justified with a weak matchup.

Hard 15 against a dealer 7 is a losing stand, so I hit to try to improve; doubling is not favorable with a weak total.

Hard 20 against a dealer 7 is a strong standing hand; hitting risks busting for no gain since only an ace would help and any hit card would bust or leave 20.

With a hard 5 against the dealer's 9, hitting is the only sound play; standing loses too often and doubling adds risk to a weak total.

Hard 12 against a dealer 9 is a hit; standing is too weak against a strong upcard, while hitting gives a chance to reach 17-21.

Hard 16 against a dealer 7 is a losing stand (dealer makes 17+ far more often than busting), so hitting maximizes equity; doubling on 16 is not viable.

Hard 19 against a dealer 3 is a strong standing hand; hitting risks busting and doubling adds variance with no real gain since 19 already beats most dealer outcomes.

Hard 20 against a dealer queen is a standing hand; hitting risks busting with no meaningful gain, and doubling adds unnecessary risk for no edge.

Hard 16 against a dealer 5 is a standing hand; the dealer is likely to bust, and hitting risks busting first.

Hard 19 is a very strong total; standing against a dealer 2 avoids busting and keeps a likely winning hand, with no reason to double.

Soft 19 against a dealer 9 is a strong standing hand; hitting or doubling risks busting or worsening a near-made total.

Hard 14 against a dealer 10 is a losing stand, so I hit to try to improve; doubling is not justified on this weak total.

Hard 19 against a dealer 10 is a standing hand; hitting risks busting with little chance to improve.

Hard 19 against dealer 4 is a strong standing hand; hitting or doubling risks busting for no gain.

Hard 13 against a dealer 9 is a losing stand, so I hit to try to improve toward 17–21. Doubling is not appropriate with a weak total against a strong upcard.

Hard 19 against a dealer 3 is a strong standing hand; hitting or doubling risks busting for no reason since 19 already beats most dealer outcomes.
