Hard 17 against an ace is a stand under basic strategy; hitting or doubling risks busting a made hand.

Soft 16 versus a dealer 6 is a basic-strategy double: the weak upcard and the Ace's flexibility make taking one more card for double the stake the highest-EV play.

Hard 20 versus a dealer ten is a clear stand; hitting or doubling risks a bust and splitting tens is negative EV.

Hard 13 versus a dealer 7 is a hit under basic strategy; standing loses too often and doubling is not justified.

Hard 15 against a dealer 7 is a hit under basic strategy, since standing loses too often when the dealer makes a hand.

Hard 17 versus a dealer 10 is a clear stand; hitting or doubling risks busting a made hand.

I have a hard 20 against a dealer 7, which is a strong made hand. Standing is clearly best; hitting, doubling, or splitting tens would only risk a winning hand.
