Blackjack table

Hard 9 against an ace is a clear basic-strategy hit; standing loses far too often and doubling is only correct against dealer 3-6.

Hard 14 against a dealer Ace is a clear basic-strategy hit; standing loses far more often since the dealer's Ace up is very strong.

Hard 15 against a dealer Ace is a clear hit; standing leaves the hand losing against most dealer outcomes, and doubling/splitting are unavailable.

Hard 13 against a dealer 3 is a standing hand in basic strategy; the dealer has a high bust probability with a small upcard.

Hard 17 is a standing hand against any dealer upcard, including a queen; hitting risks busting with little upside.

Basic strategy for a pair of 7s against a dealer 5 is to split, since each 7 played separately has better expected value than standing on 14 against a weak upcard.

Hard 16 against a dealer 5 is a standing hand in basic strategy; the dealer's high bust probability makes hitting or doubling negative EV.

Hard 17 vs dealer 5: standing is correct since hitting busts ~62% of the time and the dealer's 5 upcard is already weak. Doubling a made 17 would only add risk with no strategic edge.

Hard 15 vs dealer 2 is a basic-strategy stand in 6-deck S17 without surrender; doubling hard 15 is never correct, and hitting only becomes right against dealer 7-A or 10.

Basic strategy: hard 14 against a dealer 9 is a hit; standing leaves the hand likely losing to a made dealer 18+. Doubling only suits strong totals vs weak upcards, so hit is optimal.

Hard 17 against a dealer 9 is a standing hand; hitting risks busting with no meaningful gain since 17 already beats many dealer outcomes.

Hard 6 against a dealer 3 is far below any viable standing total; basic strategy says hit, and doubling a 6 vs 3 gives up too much EV versus drawing to a strong total.

Hard 16 against a dealer 3 is a standing hand in basic strategy; the dealer's bust probability is high with a small upcard, and hitting risks busting. Only hit 16 against dealer 7 or higher.

Hard 10 against a dealer 9 is a standard double per basic strategy; the expected value of doubling exceeds hitting.

Soft 17 against a dealer 10 is too weak to stand; basic strategy says hit (double is only correct on soft 17 vs weak upcards).

Hard 16 vs dealer 10 — basic strategy says hit; standing loses to any dealer 17+ and only wins if dealer busts.

Hard 15 vs dealer 3 is a stand per basic strategy: the dealer's 3 is a bust-prone upcard, and hitting risks busting with a stiff hand.

Hard 14 against a dealer 6 is a standard stand: the dealer's 6 is a bust-heavy upcard, so risking a hit or doubling adds more risk than reward.

Basic strategy: hard 16 against a dealer 7 is a hit, since the dealer's likely made hand of 17 beats standing on 16.

Hard 10 against a dealer ace is a hit per basic strategy; doubling is too risky against the ace even though the dealer has already peeked and confirmed no blackjack.

Hard 14 against a dealer Ace is a clear basic-strategy hit; standing loses far too often since the dealer's likely final total is 17 or better.

Hard 16 against a dealer Ace is one of the worst spots; with dealer peeking (no blackjack risk) and no surrender available, hitting is the basic-strategy play since standing loses to most dealer draws.

Basic strategy: double hard 11 against a dealer 3 — strong player total with dealer in a weak position maximizes expected value.

Hard 19 is a strong standing hand against a dealer King; hitting risks busting with little upside, and doubling is far too aggressive. Basic strategy says stand.

Hard 8 against a dealer 10 is a clear hit per basic strategy; doubling is far too weak here.

Hard 13 against a dealer 10 is a standard hit; standing loses to the dealer's likely 20 while hitting can reach 17-21.

Hard 16 against a dealer 10 is a losing standing position; basic strategy calls for hitting since standing loses ~77% while hitting improves expected value.

Hard 10 against a dealer 6 is a textbook double per basic strategy; the dealer's weak upcard gives strong expected value on the extra bet.

Hard 18 against a dealer 5 is a strong standing hand; basic strategy says stand, as hitting or doubling risks more than the expected gain.
