Blackjack table

Hard 16 against a dealer 10 is a basic-strategy hit; standing wins only when the dealer busts, while drawing can improve to 17-21 without risking extra money since a push-or-win chance outweighs the bust frequency here.

Hard 19 vs a 3 is a clear stand; doubling risks a strong hand for minimal edge.

Hard 11 against a dealer 3 is a textbook double: with the dealer standing on soft 17, doubling has higher expected value than hitting, and I can't bust with one card.

Hard 13 against a dealer 5 is a standard stand: the dealer is likely to bust, and hitting risks breaking a made hand. Doubling hard 13 vs 5 is not profitable.

Hard 17 is a made hand; standing is correct against a dealer 3 since hitting risks busting and doubling is too risky with 17.

Soft 16 (A-5) against a dealer King is a clear hit per basic strategy; doubling is only correct against weak upcards 4-6, and standing risks losing to a likely dealer 20.

Hard 16 against a dealer King is a basic-strategy hit; standing loses more often than drawing one card, and surrender is not available.

Hard 14 vs dealer 10 is a standard hit per basic strategy; standing gives poor EV and doubling is too risky here.

Hard 17 vs dealer 9: hitting risks busting (~69%) for little gain, and doubling a made 17 is far too risky. Standing is the basic-strategy play.

Hard 12 against a dealer 4 is a standard stand: the dealer's bust risk is high, and hitting risks busting with 10-value cards abundant.

Soft 18 (A-6) vs dealer 2 is a stand under basic strategy with S17; doubling is only favored vs 3-6, and hitting risks breaking a made 18.

Hard 20 is a near-certain winner; the dealer has peeked and confirmed no blackjack, so standing maximizes expected value. Hitting or doubling risks busting a made hand.

Hard 8 vs dealer ten is a clear hit; I cannot bust with one card (max 18) and standing on 8 has virtually no winning chance.

Hard 18 vs dealer 10 is a stand per basic strategy; hitting risks busting for marginal gain.

Hard 18 vs dealer Ace (peek already ruled out blackjack) is a standard stand; hitting risks busting a made hand for little gain.

Hard 15 against a dealer 3 is a basic-strategy stand; the dealer's bust risk on 3 is high enough that hitting only risks busting my own hand.

Hard 14 vs dealer 10 is a losing standing position; basic strategy says hit (surrender unavailable), taking one card to improve toward 17+.

Hard 17 is a made hand; standing is correct against a dealer 10 since hitting risks busting with little upside.

Soft 18 vs dealer 3 is a basic-strategy double in an S17 game; the dealer's weak upcard makes doubling for maximum value better than standing.

Hard 17 vs dealer 7 is a clear stand per basic strategy; hitting risks busting a made hand, and doubling 17 is far too risky.
