Blackjack table

Hard 18 is a strong hand against a dealer 3, so standing maximizes expected value without risking a bust.

Soft 18 against dealer 5 is a strong double-down spot because the dealer is likely to bust or make a low total, and doubling maximizes expected value.

Hard 15 against a dealer 2 is a basic strategy stand, since the dealer is likely to bust or make a low total.

Dealer shows a 4, likely to bust; standing on 13 is the optimal basic strategy play.

Hard 20 is a strong made hand, and the dealer shows a 3, so hitting or doubling risks a sure winning position for no benefit. Standing maximizes expected value.

Hard 17 is a strong made hand against a dealer 3, and hitting risks busting. Standing maximizes expected value here.

Hard 18 against a dealer queen is a standing hand; hitting risks busting and doubling is not profitable here.

Hard 14 against a dealer 7 is a losing hand; hitting gives the best chance to improve to a total that can beat the dealer's likely 17 or better.

Total 19 is strong; hitting risks busting with only four safe cards. Dealer upcard 7 must draw to 17 or better, so standing maximizes expected value.

Hard 20 vs dealer 10 is a strong hand; standing maximizes EV.

Hard 18 vs dealer 6 is a strong hand; standing maximizes win probability without risking a bust.

Hard 13 against a dealer 8 is a losing hand, so hitting gives the best chance to improve without risking extra chips.

Soft 18 vs dealer Ace is a weak hand; dealer likely has a strong total, so hitting improves the chance to reach 19 or better. Standing with 18 is risky, and doubling is suboptimal against an Ace.

With a hard 15 against a dealer Ace, hitting is the correct basic strategy to try to improve, since standing is very weak and the dealer is likely to make a hand.

Hard 20 is a very strong hand; the only risk is dealer blackjack, but hitting cannot improve the outcome meaningfully. Standing maximizes expected value.

Standing on 17 against a dealer 3 is correct because the dealer must stand on soft 17 and is likely to bust or make a lower total.

Dealer shows a 5, a weak upcard, and my 12 is a strong doubling spot against it. Doubling maximizes expected value here.

Total 8 is weak against a dealer 10, so I need to draw to improve the hand. Doubling on 8 vs 10 is not favorable, so hitting is the correct basic strategy.

Hard 12 against a dealer 10 is a basic strategy hit since standing loses more often than drawing, and drawing only busts with a 10-value card.

Hard 14 against a dealer 10 is a losing hand, and standing gives a poor chance to win, so hitting is the correct play to try to improve.

Dealer shows a Jack, so I need to improve my soft 17. Hitting is the best play to try to reach a stronger total.

I have a strong 20 and the dealer shows a face card; standing gives the best chance to win or push. Hitting cannot bust but risks turning a winning hand into a worse one.

Dealer shows a 6, which is a favorable upcard for the player, and standing on 12 avoids the risk of busting against a likely dealer bust hand.
