Blackjack table

With A-A against a dealer 8, splitting is the standard basic-strategy play. Each Ace starts a fresh hand with strong doubling potential and avoids the weak 12 total.

Hard 17 against an Ace is a classic stand hand; hitting risks busting with no realistic chance to improve to a winning total, and doubling would be reckless with a stiff hand.

Soft 16 vs dealer 6: doubling risks busting with a weak soft total, so I hit to improve to a stronger hand while the dealer is weak.

Standing on 14 against a dealer 6 is the correct basic strategy play since the dealer is in a weak position and likely to bust.

Hard 20 is a very strong hand; standing maximizes expected value against the dealer's 10 upcard and avoids the risk of busting.

Hard 13 vs dealer 7 is a classic hit; standing loses more often than hitting due to dealer's likely 17+.

Standing on 15 against a dealer 7 is the mathematically correct basic strategy play, as hitting risks busting with a high probability of drawing a 10-value card.

I have a hard 20 against a dealer 7, which is a strong hand. Standing avoids the risk of busting and is the optimal basic strategy play.

Standing on 16 against the dealer's 9 is the mathematically correct play; hitting risks busting with a high probability, and doubling is not advisable with such a weak total.

With a hard 10 against dealer's 10, doubling is risky and standing is weak; hitting gives a chance to improve to a strong total without committing extra chips.

Hard 12 against dealer's 10 is a classic marginal spot; hitting avoids the high bust risk of standing while the dealer likely has a strong hand. With no doubling or splitting available, hitting is the only reasonable play.

Hard 14 against a 10 upcard is a losing hand regardless of action, but standing minimizes expected loss compared to hitting into a high bust probability. I'll take the dealer's bust risk.

Standing on 15 against a dealer 9 is the mathematically correct basic strategy play; hitting risks busting with a high probability and doubling would be worse.

Standing on 17 against a dealer 6 is the correct basic strategy play; doubling is not recommended on a hard 17.

Standing on 13 against a Jack is the correct basic strategy play to avoid busting, and doubling would be too risky with a weak total.

Hard 12 vs dealer Q is a basic-strategy stand, but doubling a weak 12 is unfavorable; hitting keeps the hand alive and avoids busting with a stiff total against a strong upcard.

With a hard 9 against a dealer 2, doubling is statistically favorable because the dealer's weak upcard increases the chance of the dealer busting or ending with a low total, and I have a strong starting hand to capitalize on the double bet.

Standing on 15 against a dealer 7 is the correct basic strategy play; hitting risks busting with a weak upcard and no dealer blackjack peek concern here.

Soft 13 against a dealer 2 is a marginal double in 6-deck games; I'm doubling to capitalize on the weak upcard and the favorable soft total.

Standing on 18 against a dealer 4 is the correct basic strategy play, as the dealer is weak and hitting risks busting.

Hard 9 vs dealer 3 is a basic-strategy hit; doubling is not recommended here, so I take a card to improve the hand.

Standing on 18 is the correct basic strategy play against a dealer 3, as hitting risks busting with little gain.

Soft 17 against a dealer 7 is a marginal spot; standing avoids busting while the dealer is likely to make a moderate hand, and doubling is too risky given the dealer's upcard strength.

Hard 17 against a dealer 9 is a stand under basic strategy; hitting risks busting with little gain. Doubling is not recommended at this total.

Standing on 16 vs dealer J avoids busting and is the least bad option since doubling would risk 20 chips on a weak hand.
