Blackjack table

Hard 20 against a dealer jack is already a strong made hand, so standing is clearly best. Hitting, doubling, or splitting tens would only risk a winning total.

Hard 15 versus a dealer 10 is a hit under basic strategy; standing loses more often and doubling is too risky.

Hard 19 against a dealer 10 is a strong made hand; standing is the clear basic-strategy play rather than risking a bust by hitting or doubling.

Soft 18 versus a dealer 2 is a basic-strategy stand: the hand is already strong and doubling or hitting risks a worse total against a weak upcard.

Pair of 8s totals 16 against a dealer 10-value upcard; splitting is the basic-strategy play because 16 is a weak total and two separate 8s give better expected value than hitting or standing.

Hard 18 against a dealer queen is a clear stand; hitting or doubling risks busting a strong total.

Soft 19 versus a dealer ten is a strong made hand; basic strategy is to stand rather than hit or double.

Hard 20 is a made hand against a dealer 5; standing avoids busting and is the highest-EV basic-strategy play.

Hard 14 versus a dealer 10 is a clear hit in basic strategy; standing loses too often and doubling is not justified.

Hard 16 versus a dealer 7 is a hit under basic strategy; standing loses more often and doubling is far too risky.

Hard 17 against a dealer 7 should stand; hitting busts on any card 5 or higher and is a large negative expectation.

Hard 13 versus a dealer 2 is a basic-strategy stand: the dealer is more likely to bust than to beat a made 13, and hitting risks busting.

Hard 20 against a dealer 5 is already a strong made hand; standing avoids bust risk and is the clear basic-strategy play.

Hard 12 versus a dealer 9 is a hit in basic strategy; standing loses too often and doubling is a poor value.

Hard 13 against a dealer 9 is a hit under basic strategy; standing loses too often to a made dealer hand.

Hard 18 versus a dealer 2 is a strong made hand; standing is the correct basic-strategy play.

Hard 19 against a dealer 5 is a strong made hand; standing is the clear basic-strategy play, while hitting or doubling risks a bust or a worse total.

Hard 9 versus a dealer 10 is a hit in basic strategy; doubling is only correct against weak upcards.

Hard 16 against a dealer 10 is a basic-strategy hit; standing loses too often when the dealer makes a hand.

Hard 15 versus a dealer 7 should be hit under basic strategy; standing loses too often and doubling is not justified.

Hard 19 versus a dealer 8 is a strong made hand; standing is the clear basic-strategy play, while hitting or doubling risks busting a likely winner.

Hard 17 versus a dealer ten is a clear stand; hitting or doubling risks busting a made hand.

Soft 18 versus a dealer 4 is a basic-strategy double in a multi-deck game where the dealer stands on soft 17, and doubling is legal.

Hard 13 against a dealer 8 is a hit under basic strategy, since standing loses too often to dealer 18.
