Blackjack table

With hard 13 against the dealer's 6, standing is correct basic strategy because the dealer is likely to bust. Hitting or doubling would unnecessarily risk busting a made total.

Hard 6 against a dealer Ace is a clear hit; doubling is not favorable with such a low total, and standing would surrender too much equity.

With a hard 13 against the dealer's Ace, standing is too weak; hitting gives the best chance to improve without busting on the next card.

Hard 15 against an Ace is a losing stand, so I hit to try to improve; the dealer has already peeked for blackjack, so this decision only matters when the dealer does not have a natural.

I have a hard 19, which is a strong total; standing is correct against any dealer upcard, including an Ace.

Hard 14 against a dealer 10 is a losing stand, so I hit to try to improve without risking an extra double bet.

I have a hard 20, and the dealer's upcard is a Jack without blackjack (peeked). Standing maximizes my chance to win or push, while hitting risks busting.

Hard 19 against a dealer 4 is a strong standing hand; hitting or doubling risks busting or reducing expected value.

Hard 10 against a dealer 10 is a hitting hand, not a double; splitting 5s is also poor. Hit to maximize expected value.

Hard 14 against a dealer 10 is a losing stand, so hitting is the correct basic-strategy play to try to improve toward 17-21.

Hard 10 against a dealer 9 is a profitable double spot in 6-deck S17 blackjack, and doubling is legal on the first two cards. Splitting the 5s would be much weaker than treating the hand as a 10.

With a hard 11 against a dealer 3, doubling is the optimal basic-strategy play, maximizing value while I am favored to improve to a strong total.

Hard 10 against a dealer 4 is a strong double-down spot, maximizing expected value with one card to come.

I have a hard 20 against a dealer 7; standing is clearly best since doubling or splitting would risk a near-locking hand for no strategic gain.

Hard 12 against a dealer 3 is a basic-strategy hit; standing risks losing to many dealer outcomes while hitting improves the total without busting on most cards.

Dealer upcard 3 is weak, and standing on hard 14 avoids busting while giving the dealer a good chance to break.

Hard 10 against a dealer 8 is a standard double-down spot: hitting once with doubled stake maximizes expected value given the dealer's weak upcard.

Hard 12 against a dealer 10 is a hitting hand; standing risks losing immediately to a made dealer hand, while hitting gives a chance to reach 17–21.

I have a hard 19 against the dealer's queen, so standing is the strongest play; hitting risks busting for no benefit.

With a hard 11 against the dealer's 3, doubling is the optimal play to maximize expected value by getting one card while increasing the bet.

Hard 12 against a dealer 8 is a losing stand, so I hit to try to reach 17–21. Doubling is not appropriate with a weak total against a strong dealer upcard.

Hard 6 against a dealer 8 is a clear hit; doubling is not favorable, and standing on 6 would be too weak.

Hard 15 against a dealer 8 is a losing stand, so I hit to try to improve to a stronger total.

Hard 19 against a dealer 8 is a strong standing hand; hitting risks busting and gains little since the dealer must hit to 17 and often already has a made hand.

A hard 20 is strong; standing avoids risking a bust against the dealer's Ace.

With hard 11 against a dealer 10, doubling is the optimal basic-strategy play because it increases the wager while giving a strong chance to make 21.

With a hard 14 against the dealer's 3, basic strategy is to stand and let the dealer take the risk of busting.
