Blackjack table

Hard 9 versus a dealer 3 is a standard double: the dealer is weak (bust card), and doubling maximizes expected value on this favorable matchup.

Hard 16 against a dealer 7 is a stand in multi-deck basic strategy; hitting risks busting, and the dealer is likely to make a standing total.

Hard 17 against a dealer 2 is a standing hand; hitting risks busting and doubling is not favorable.

I have a hard 20, which is a very strong hand. The dealer shows a Jack, so standing is the optimal play to avoid busting and likely win or push.

Hard 20 against a dealer 9 is a strong standing hand; hitting or doubling risks busting, and splitting tens is not favorable here.

Hard 16 against a dealer 10 is a losing stand, so I hit to try to improve; doubling is not appropriate on this total.

Hard 18 versus a dealer 10 (K). Basic strategy says stand on 18 against a 10, since hitting risks busting and the dealer already lacks blackjack (peek passed). No double or split available.

Hard 15 against a dealer 10 is a losing stand; basic strategy says hit, and doubling on 15 vs 10 is not justified.

Hard 17 against a dealer 10 is a standing hand; hitting risks busting with little chance to improve.

Soft 17 against a dealer 10 is a hitting hand in multi-deck S17 basic strategy; standing on 17 risks losing to any dealer made hand, while hitting can improve without busting immediately.

Soft 18 is weak against a dealer 10, and with no double available the correct basic-strategy play is to hit and try to improve.

I have a total of 20 against the dealer's Jack, so standing is the strongest play and avoids risking a bust.

Soft 15 against a dealer 7 is not strong enough to stand or double; hitting is the standard play because the hand cannot bust and can improve with many cards.

Hard 15 against a dealer 7 is a losing stand, so I hit to try to improve toward 17–21 while the dealer is not in a bust-prone upcard range.

I have a strong total of 20, and the dealer's upcard is a ten but has already peeked for blackjack (no blackjack), so standing avoids busting and maximizes expected value.

With a hard 5 against a dealer 6, hitting is correct; doubling would lock me into one card and a likely weak final total.

Hard 7 against a dealer 6 is still too weak to stand; basic strategy says to hit and try to improve toward a stronger total.

Hard 17 against a dealer 6 is a standing hand; the dealer is likely to bust, and hitting risks busting before the dealer acts.

Hard 20 is a very strong hand; standing maximizes expected value against a dealer 4 upcard, and doubling would only add risk without improving the hand.

Dealer upcard 5 is a bust card; with hard 12, standing avoids busting and lets the dealer draw into a likely bust.

With a total of 20 against dealer's 9, standing is the optimal play; splitting or doubling would reduce expected value.

Hard 10 against a dealer 5 is a strong double opportunity, maximizing expected value by getting more money in while the dealer is likely to bust.

Hard 9 against a dealer 3 is a strong double opportunity, so I will double to maximize expected value.

Hard 12 against a dealer 3 is a hitting hand; standing risks losing to a likely dealer made hand, and doubling is not justified on 12.

Hard 17 against dealer upcard 3; basic strategy says stand, as hitting risks busting and the dealer must draw to 17+ from a weak 3.

Hard 20 against dealer 7 is a strong standing hand; doubling would risk a near-certain win for no gain, and splitting tens is -EV.
