Blackjack table

Hard 14 against a dealer 10 is a basic strategy hit, since standing on 14 loses more often than taking a card does. The dealer has already peeked and has no blackjack, so there is no extra risk from that.

Hard 16 against a dealer 6 is a standard stand, since the dealer is most likely to bust. Doubling on 16 is not correct basic strategy.

Hard 18 against a dealer 8 is a stand in basic strategy; hitting risks busting and doubling has negative expected value.

Hard 9 against a dealer Ace is best played as a hit under basic strategy, since doubling is not favorable against an Ace. The dealer has already peeked and has no blackjack.

Hard 19 is a strong total, and hitting risks busting with almost any card beyond an Ace or deuce, so standing is correct even against a dealer Ace.

Hard 12 against a dealer 2 is a hit in basic strategy, since standing on 12 against a 2 is slightly worse. Doubling is not recommended with this hand.

Hard 9 against a dealer 10 is a hit in basic strategy; doubling is only marginal against a ten, so hitting is the standard play.

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

Hard 14 against a dealer 7 is a hit by basic strategy, since the dealer's likely total is 17 and standing on 14 loses more often. Doubling is not recommended on a hard 14.

Hard 8 against a dealer 4 is best played by hitting under basic strategy. Doubling only becomes correct on totals of 9 to 11 here, and 8 is too weak to justify the extra bet.

Hard 13 against a dealer 4 is a stand by basic strategy, since the dealer busts often with a weak upcard and hitting risks busting my own hand.

Hard 9 against a dealer 6 is a standard double, since the dealer is most likely to bust and one extra card gives a strong chance at a good total.

Hard 20 against a dealer ten is a strong made hand; standing is optimal, and splitting tens or doubling has lower expected value.

Hard 17 against a dealer 3 is a stand in basic strategy; hitting risks busting and doubling is not favorable.

Soft 14 (A,3) against a dealer 6 is a standard double in basic strategy, since the dealer is likely to bust and doubling is allowed on any first two cards.

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

Hard 17 against a dealer 6 is a stand in basic strategy, since the dealer busts often and hitting or doubling would be worse.

Hard 11 against a dealer 10 (K) is a close call in a multi-deck game with a stand-on-all-17s dealer. Basic strategy for 6 decks with S17 says to hit, since doubling is only favored against 2 through 9 and the dealer has already peeked for blackjack.

Hard 19 against a dealer 3 is a clear stand; hitting or doubling would add risk with no positive expected value.

Hard 13 against a dealer 8 is a losing stand, since the dealer is likely to make 18 or better. Basic strategy says to hit, and doubling is not recommended.

Hard 14 against a dealer ten is a losing spot either way, but basic strategy says hit because standing on 14 loses more often than hitting. Surrender is not offered and doubling is clearly worse.

Hard 18 against a dealer ten is a stand; hitting risks busting and is worse in expectation.
