Blackjack table

Hard 12 against a dealer 7 is a basic-strategy hit: standing wins too rarely since the dealer likely makes 17-20, while drawing one card improves the hand without high bust risk.

Hard 19 is a strong made hand; standing is correct against a dealer 7, since hitting risks busting for negligible gain.

Basic strategy: hard 9 doubles against a dealer 5 (dealer bust card, stands on soft 17), maximizing expected value.

Hard 10 against a dealer 6 is a basic strategy double; the dealer's high bust probability makes maximizing the bet on this favorable spot correct.

Hard 9 against a dealer King (10) is a clear hit per basic strategy; doubling against a 10 has negative expected value, and standing on 9 gives almost no chance to win.

Hard 16 against a dealer 10 is a classic hit per basic strategy; standing on 16 has worse expected value since the dealer likely makes 17-21, and only a 5 or less busts me.

Hard 11 vs dealer 10 in 6-deck S17 with peek: basic strategy favors doubling (one strong draw card), and dealer blackjack risk is eliminated by the peek.

Hard 8 against a dealer queen is a clear hit per basic strategy; splitting 4s into a strong 10-value upcard is unfavorable, and doubling is too risky with a weak total.

Hard 11 against a dealer 10 (Queen) is a clear hit; standing on 11 almost always loses, and doubling is unavailable with three cards.

Hard 14 against a dealer 9 is a basic-strategy hit; standing loses more often than drawing, and doubling is too risky here.

Hard 6 against a dealer 3 is a clear basic-strategy hit; doubling is only profitable on 9-11, so I take one card and reassess.

Hard 16 vs dealer 3 is a basic-strategy stand; hitting risks busting against a weak upcard where the dealer likely breaks.

Hard 14 vs dealer 7 is a basic-strategy hit: standing loses to the dealer's likely 17, while drawing improves expected value despite bust risk.

Hard 17 vs dealer 10: standing is basic strategy; hitting risks busting a made hand for minimal gain, and doubling a 17 is not viable.

A pat 20 against a dealer Queen is a strong standing hand; splitting tens or doubling would only sacrifice expected value.

Hard 17 against a dealer 5 is a clear stand in basic strategy; doubling a made 17 risks turning a likely win into a bust.

Hard 19 vs dealer 10 is a strong standing hand; hitting or doubling would only risk ruin with negligible EV gain.

Hard 7 against a dealer 10 is a clear hit per basic strategy; doubling is far too weak here, and standing on 7 has almost no chance to win.

Hard 9 against a dealer 10 is a clear hit per basic strategy; standing on 9 gives almost no chance to win.

Hard 18 vs dealer 10 is a standard stand; hitting risks busting a made hand with only marginal gain.

Soft 15 (A-4) against a dealer 9 is a clear hit per basic strategy; doubling is only correct against weak upcards 4-6, and standing leaves the hand far too weak.

Hard 15 against a dealer 9 is a basic-strategy hit; standing loses against the dealer's likely 19, and only a 4-8 improves safely while busting risk is acceptable.

Hard 16 (4-A-J-A) against a dealer 9 is a basic-strategy hit; standing only wins if the dealer busts, while drawing can improve to 17-21 without busting risk beyond one card.

Hard 20 against a dealer 9 is a near-certain winner; hitting would bust on any card except an ace, so standing maximizes expected value.

Soft 17 against a dealer ace is too weak to stand; basic strategy says hit (doubling is only correct against 3-6). Dealer peek already ruled out blackjack.

Hard 13 against a dealer ace is a clear basic-strategy hit; standing leaves almost no chance to win against a likely strong dealer total.

Basic strategy: 14 (7,7) vs dealer 10 is a hit; splitting sevens against a ten just doubles exposure to a strong dealer hand.

Hard 19 is a made hand; standing is clearly optimal against a dealer 10 since hitting risks busting with almost no upside.

Hard 19 against a dealer 10 is a strong standing hand; hitting risks busting for minimal gain, and doubling is far too risky.

Soft 19 vs dealer 5 is a standing hand under basic strategy in an S17 game; doubling is only marginally considered vs 6, so standing maximizes expected value here.
