Blackjack table

Hard 17 against a dealer 6 is a standard stand, since the dealer is likely to bust and hitting risks busting a made hand.

Hard 18 against a dealer 4 is a standard stand; hitting or doubling would lower expected value.

Hard 19 against a dealer King is a strong hand; standing is the basic strategy play, since hitting or doubling would risk busting or lose value.

Hard 14 against a dealer 7 is a hit under basic strategy, since a dealer 7 is likely to make a strong hand and standing on 14 is a losing play. Doubling is not recommended on 14.

Hard 19 against a dealer 7 is a clear stand; hitting risks busting for very little gain.

Hard 15 against a dealer ten is a weak spot, and with no surrender available basic strategy says to hit, since standing loses more often than hitting in the long run.

Hard 18 against a dealer 10 should stand; hitting risks busting too often and the expected value of standing is better.

Hard 9 against a dealer 3 is a standard double in a multi-deck game, since it has positive expected value from the extra bet when the dealer is likely to bust or end up weak.

Hard 6 against a dealer 4 is too weak to stand on, and basic strategy says to hit rather than double on totals under 9. Hitting is correct.

Hard 16 against a dealer 4 is a standard stand, since the dealer is likely to bust and hitting risks busting with many ten-value cards remaining.

Hard 15 against a dealer 8 is a basic strategy hit; standing is only correct against 2-6, and doubling is not favorable with 15 vs 8.

Hard 18 against a dealer 8 should stand; hitting risks busting and gains little, and standing is better than hitting.

Hard 13 against a dealer Ace (dealer peeked, so no blackjack) is a weak hand; basic strategy says hit, since standing on 13 loses more often against a strong upcard.

Hard 20 is a very strong hand; standing is basic strategy, and splitting tens against a dealer 6 is not worth the added risk.

Soft 18 against a dealer 9 is a hit in basic strategy, since doubling is only correct against 3-6 and standing is only correct against 2, 7, 8 (and 9 favors hitting in both S17 and H17 rules). Hitting can't bust and improves the hand's expected value.

Hard 13 against a dealer 9 is a hit under basic strategy, since standing on 13 loses more often than risking a bust.

Hard 17 (A counted as 1: 7+1+5+4=17) against a dealer 9 is a stand; hitting risks busting too often and has lower expected value.

Hard 19 against a dealer 9 is a clear stand; hitting risks busting and doubling has negative expectation.

Hard 12 against a dealer 7 is a basic strategy hit, since the dealer is likely to make a hand of 17 or better and standing on 12 is weaker. Doubling is not advisable with this total.

Hard 15 against a dealer 7 is a hit by basic strategy: the dealer likely makes 17 or better, so standing on 15 loses more often than hitting.

Hard 13 against a dealer 6 is a standard stand, since the dealer is most likely to bust. Doubling on 13 is not correct basic strategy.

Hard 13 against a dealer 3 is a basic strategy stand, since the dealer is likely to bust or end with a weak total.

Hard 19 against a dealer 10 is a clear stand; hitting risks busting and doubling has negative expected value.

A hard 20 against a dealer ten is a strong hand, and standing beats splitting tens or doubling in expected value.

Hard 16 against a dealer 8 is a basic strategy hit, since standing loses more often than hitting in the long run. Doubling is not appropriate on a hard 16.

Hard 17 against a dealer King is a stand in basic strategy; hitting risks busting too often, and doubling is clearly worse.
