Model's stated reason
A hard 17 against a dealer 7 is a stand; hitting risks busting and has lower expected value.
Model's stated reason
A hard 17 is strong enough to stand, especially against the dealer’s 5, where the dealer has a high chance of busting.
Model's stated reason
Standing on 20 is the optimal play; hitting risks busting, and doubling or splitting would weaken a strong hand.
Model's stated reason
Stand on hard 16 against the dealer’s 6; the dealer has a strong chance to bust, and hitting risks busting immediately.
Model's stated reason
Hit 12 against the dealer’s 9; standing has a poor expected outcome, and doubling is not strategically appropriate.
Model's stated reason
An 11 against a dealer 4 is a strong doubling opportunity; taking one card maximizes value against the dealer’s vulnerable upcard.

Stand on hard 15 against the dealer’s 4; the dealer is more likely to bust, so hitting risks breaking a hand that can win by waiting.
