Blackjack table

Hard 10 vs dealer 10 is a clear hit in basic strategy; doubling here is a long-term mistake, so I take a card to improve.

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

Splitting 5s against a dealer 5 is a standard basic-strategy play to create two hands starting with 5, which can be doubled down effectively; the dealer's weak upcard increases the chance both hands improve.

Standing on 15 against the dealer's 5 is the correct basic strategy play, as the dealer is likely to bust with a weak upcard. Doubling would be too risky with a marginal total, and hitting risks busting immediately.

Hard 9 vs dealer 5 is a classic double-down spot; the dealer's weak upcard makes doubling the 10-chip bet highly favorable for maximizing expected value.

Standing on 15 against a dealer 6 is correct basic strategy; the dealer is likely to bust with a weak upcard.

Soft 19 against a dealer 3 is a strong hand; standing minimizes risk of busting and is the basic-strategy play.

Splitting 8s is the mathematically correct play against a dealer 3 upcard in a 6-deck game, as it reduces losses compared to playing a hard 16.

Hard 15 vs dealer 3 is a stand under basic strategy; hitting risks busting with little gain, and doubling is not recommended on a hard 15.

Soft 19 against a dealer 3 is a strong standing hand; hitting risks turning the Ace into a 10-value card and busting to a worse total.

My hand totals 20, which is a very strong position. Standing is the optimal play against a dealer's 2 upcard to avoid busting.

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

My hand totals 19, which is a strong standing total against the dealer's 7 upcard. The risk of busting by hitting outweighs the small chance of improving to 20 or 21.

Standing on 20 against a King upcard is the optimal basic strategy play; hitting risks busting with little chance to improve.

Hard 10 vs dealer 9 is a classic double opportunity, but with only 5 decks remaining and no true count, I prefer to hit to avoid busting and keep the hand flexible. Standing on 10 is clearly inferior, and doubling here is too aggressive without an edge.

Standing on 17 against a 9 avoids busting and is the correct basic-strategy play; hitting risks turning a likely win into a loss.

Standing on 20 against a dealer 3 is clearly correct; hitting risks busting with no realistic path to improvement, and doubling is inappropriate with such a strong total.

Standing on 19 against a Queen upcard is the correct basic strategy play, as hitting risks busting with little chance to improve to a winning hand.

Standing with 15 against a dealer King is the correct basic strategy play, as hitting risks busting with a high card and the dealer's strong upcard makes improvement unlikely.

Hard 12 vs dealer 9 is a weak hand; hitting minimizes long-term loss compared to standing, and doubling is too risky with only one card to improve.

Standing with 14 against a 9 avoids busting and relies on the dealer's high bust probability; doubling is not allowed here.

Standing on 17 vs dealer 8 is the correct basic strategy play; hitting risks busting with little gain.

Hard 12 against dealer's 7 is a weak standing hand with high bust risk if I stand; hitting gives a chance to improve to a playable total.
