Blackjack table

Hard 17 against a dealer 6 is a standing hand; the dealer is most likely to bust, and hitting or doubling a made 17 risks busting for no gain.

Hard 18 against a dealer 4 is a strong standing hand; hitting risks busting and doubling is not warranted with 18.

Hard 19 against a dealer King is a strong standing hand; hitting risks busting and doubling is pointless with 19 since only an ace or 2 improves it marginally while risking a bust.

Hard 14 against a dealer 7 is a losing stand, so I hit to try to improve; doubling is not correct for this total versus a strong upcard.

Hard 19 against a dealer 7 is a strong standing hand; hitting risks busting with little chance to improve.

Hard 15 against a dealer 10 is a losing stand, so I hit to try to improve; doubling is not justified on a weak total.

Hard 18 against a dealer jack is a strong standing hand; hitting risks busting with little upside since the dealer must still make a hand.

Hard 9 versus dealer 3 is a standard double-down spot; doubling maximizes expected value by getting more money in while the dealer is likely weak.

Hard 6 against a dealer 4 is a clear hit; standing on 6 risks losing to almost any dealer total, and doubling is not favorable with such a low total.

Hard 16 against dealer upcard 4 is a standing hand in multi-deck basic strategy; hitting risks busting when the dealer is likely to break.

Hard 15 against a dealer 8 is a losing standing hand and doubling is too risky; basic strategy is to hit and try to improve.

Hard 18 against a dealer 8 is a standing hand; hitting risks busting with little chance to improve, and the dealer must still draw to 17 or more.

Hard 13 against a dealer Ace is a losing stand, so I hit to try to improve toward 17-21. Doubling is not appropriate with a weak total against an Ace.

I have a hard 20 against the dealer's 6, so standing is clearly optimal. Doubling or splitting would only risk a strong winning hand.

Soft 18 against a dealer 9 is a hitting situation in multi-deck basic strategy because standing loses too often to the dealer's likely 19 or 20. Doubling is not appropriate here, so I take one card.

With a hard 13 against the dealer's 9, standing loses too often; hitting is the correct basic-strategy play to try to improve to 17 or better.

Hard 17 against dealer 9 is a standing hand; hitting risks busting with little chance to improve against a strong upcard.

Hard 19 against a dealer 9 is a standing hand; hitting risks busting on a strong total with no upside.

Hard 12 against a dealer 7 is a losing stand, so I hit to try to reach 17–21. Doubling is not favorable with 12 versus a strong dealer upcard.

Hard 15 against a dealer 7 is a losing stand, so I hit to try to improve toward 17 or better.

With a hard 13 against the dealer's 6, standing is the correct basic-strategy play because the dealer is likely to bust.

Hard 13 against a dealer 3 is a standing hand in basic strategy; the dealer is likely to bust, and doubling would be too risky.

Hard 19 against a dealer king is strong enough to stand; hitting or doubling risks busting or adding unnecessary exposure with no realistic improvement.

I have a hard 20, which is a very strong hand. Standing is optimal since hitting risks busting and doubling would add unnecessary risk with no chance to improve a 20.

Hard 16 against dealer's 8 is a losing stand, so I must hit to try to improve; doubling on 16 is far too risky.

Hard 17 against a dealer king is a standing hand; hitting risks busting and doubling is not favorable.
