Blackjack table

Always split aces: each ace starts a strong hand, and the dealer's 4 is a weak upcard.

Double down on 10 versus the dealer's 2; this is a favorable high-value doubling situation.

Split 4s against a dealer 3; two hands starting from 4 have better expected value than playing a hard 8.

Stand on hard 14 against the dealer's 3; the dealer is relatively likely to bust, while hitting carries substantial bust risk.

An 8 is too weak to stand against a dealer 3, and doubling is not favorable. Hitting has the best expected value; splitting 4s is generally reserved for dealer 5 or 6 with double-after-split.

Hard 14 against a dealer 3 should hit under basic strategy; the dealer's weak upcard does not make 14 strong enough to stand.

Hard 17 stands against a dealer 10 under basic strategy; hitting has a high bust risk.

With a hard 8 against the dealer's Ace, hitting is the best basic-strategy play; doubling is not favored.

Hit: hard 10 against an ace is far too weak to stand, and doubling is no longer legal after the third card.

Stand on hard 18 against the dealer Ace; hitting has too high a bust risk and does not improve expectation.

Stand on hard 19 against an 8; drawing is far more likely to worsen a strong total.

Double 9 against dealer 5: the dealer is vulnerable to busting and a single additional card has strong value.

Double 9 against a dealer 5: the dealer is vulnerable to busting, and improving with one card has strong expected value.

Soft 18 should stand against a dealer 8 under standard multi-deck S17 basic strategy; doubling is not favorable here.

Stand on hard 17 against a dealer 10; hitting has a high bust risk and basic strategy stands.

Stand on hard 20; it is an excellent total and hitting or doubling only adds unnecessary bust risk.

Stand on 20; it is an excellent total and the dealer's 6 is a weak upcard.

Hit 12 against a dealer 2; standing is slightly worse under standard multi-deck basic strategy.

Stand on hard 16 against a dealer 2; the dealer is relatively likely to bust, while hitting risks busting immediately.

Soft 17 against a dealer 7 is a hit under basic strategy; doubling is not favorable against this upcard.

Hit hard 16 against a dealer 7; standing gives the dealer too much advantage.

Hard 12 against a dealer 10 is best played by hitting; standing loses too often to the dealer's likely strong total.

With a hard 8 against a dealer 10, hitting is the standard play; doubling is not favorable.

Stand on hard 17 against a dealer 10; hitting has a high bust risk and is not favorable.

Standing on hard 18 against a dealer 9 is the highest-value basic strategy play; hitting has too much bust risk.
