Blackjack table

Hard 13 vs dealer 3 is a classic hit/stand borderline; I'll hit to improve, since standing on 13 is marginal and the dealer's weak upcard doesn't justify standing yet.

Hard 9 vs dealer 3 is a classic double-down spot, but with a 1000 starting bankroll and only 990 remaining after the first bet, I'm preserving capital by hitting rather than risking another full bet on a single card draw.

Soft 20 is a very strong hand; hitting risks busting with little gain, so standing is optimal against the dealer's 3.

Hard 12 against dealer's 10 is a weak hand; hitting is the statistically correct play to avoid standing on a likely losing total, and doubling is too risky here.

Standing on 17 against a dealer Ten is the correct basic strategy play; hitting risks busting with little chance to improve to a winning total.

Standing on 19 is the correct basic strategy play regardless of the dealer's 9 upcard, as hitting risks busting with little chance of improving to a winning total.

Standing on 15 against a dealer 2 is the basic-strategy play; hitting risks busting on a 7 or higher, and doubling is not justified with a weak total.

Standing on 18 against a dealer 4 is the correct basic-strategy play; doubling would risk turning a strong hand into a bust with no meaningful edge.

Standing on 15 against a dealer 2 is the correct basic strategy play; hitting risks busting with a weak hand.

Hard 11 against dealer's Q is a strong double-down spot; I'll risk 10 more to maximize expected value on a near-guaranteed 10-value card.

Standing on 16 against a dealer 9 is a clear loser; hitting minimizes expected loss. Doubling a hard 16 is far too risky, so hitting is the best option.

Dealer's 5 is a weak upcard, and doubling a soft 13 maximizes expected value against it.

Hard 20 is a very strong hand; standing maximizes the chance to beat the dealer's weak 5 upcard without risking busting or giving up the advantage of doubling a marginal hand.

Standing on 14 against a dealer J is the mathematically correct play to avoid busting, as hitting gives a high probability of drawing a 7 or higher and going over 21.

Holding a hard 20 against a Queen upcard is a strong position; hitting risks busting with little gain, and doubling is unnecessary.

Dealer shows a weak 5 upcard, so standing on 14 is the correct basic strategy play to avoid busting and let the dealer likely bust instead.

Standing on 15 against a dealer 3 is the basic strategy play; hitting risks busting on a 10-value card, and doubling is not recommended with a hard 15.

Standing on 16 vs dealer 8 minimizes expected loss; hitting risks busting and doubling is unfavorable with a weak total.

Standing on 16 vs dealer 8 avoids busting and lets the dealer risk busting with a weak upcard; doubling is too risky with a marginal total.
