Blackjack table

Hard 13 against a dealer Ace (dealer peeked, so no blackjack) is weak; basic strategy says hit, since standing loses more often than drawing does.

Hard 14 (3, T, A counted as 1) against a dealer Ace is a losing stand; basic strategy says hit, since the dealer peeked and has no blackjack and is likely to make a hand of 17 or better.

Hard 9 against a dealer ten is a hit in basic strategy; doubling is only correct against a 2 through 6 upcard, and the dealer's Queen makes it unfavorable.

Hard 16 against a dealer ten is a losing spot either way, but hitting loses slightly less than standing in basic strategy. With three cards already in hand, the 16 is not a composition-dependent exception, so hit.

Hard 17 (4+5+7+A with the ace counted as 1) against a dealer Queen: hitting risks busting too often, so standing is the standard play.

Hard 16 against a dealer 7 is basic strategy to hit, since the dealer likely has a made hand of 17 or better and standing wins too rarely. Doubling is not advisable on 16.

Hard 20 against a dealer ten is a strong hand; standing is basic strategy and splitting tens is lower EV.

Hard 19 against a dealer King is a strong standing hand; hitting or doubling would carry too much bust risk and lower expected value.

Hard 20 against a dealer ten is a strong made hand; standing beats splitting tens, which is a worse expected value play in basic strategy.

Soft 15 (A,4) against a dealer 3 is a close call: basic strategy for S17 says double against 4-6 only, so against a 3 the correct play is to hit.

Soft 17 (A,4,2) against a dealer 3 is a hit by basic strategy; doubling is not legal with three cards, and hitting a soft hand cannot bust it.

Hard 13 (4+A+2+6 with the ace counted as 1) against a dealer 3 is a stand in basic strategy, since the dealer busts often with a weak upcard.

Hard 15 against a dealer 9 is a basic strategy hit; standing loses more often, and doubling on 15 is not favorable.

Hard 16 against a dealer ten is a weak spot, and basic strategy says to hit. No surrender is available, and the dealer has already peeked for blackjack.

Hard 20 against a dealer 7 is a very strong hand, so standing is the best basic-strategy play. Splitting tens is not worth the risk.

Hard 19 is a strong made hand; basic strategy says stand against a dealer 5, which is a weak upcard likely to bust.

Hard 19 against a dealer ten is a clear stand; hitting or doubling would carry a high bust risk and lower expected value.

Hard 11 against a dealer 7 is a standard double; it has strong positive expected value and doubling is legal on the first two cards.

Hard 15 against a dealer 5 is a standard stand in basic strategy, since the dealer busts often with a weak upcard. Doubling is not recommended with a hard 15.

Hard 12 against a dealer ten is a basic strategy hit; standing relies on the dealer busting, which is less favorable than taking a card.

Hard 19 against a dealer ten is a clear stand; hitting risks busting with most cards and gains little.

Hard 17 against a dealer 8 is a standard stand; hitting risks busting and doubling has negative expected value.

A hard 20 against a dealer 5 is a strong hand, and basic strategy says to stand. Splitting tens is not worth the added risk even against a weak upcard.
