Blackjack table

Hard 14 against a dealer 10 is a losing standing position; basic strategy calls for a hit since only 2-6 upcards favor standing.

Hard 15 against a dealer 8 is a clear basic-strategy hit: standing loses to the dealer's likely 18-20, and the bust risk is outweighed by the need to improve.

Hard 18 against a dealer 8 is a clear stand in basic strategy; hitting risks busting while 18 already beats most dealer outcomes from an 8 upcard.

Hard 10 against a dealer 4 is a textbook double per basic strategy; expected value is maximized by increasing the bet with a strong drawing hand against a weak upcard.

Hard 19 is a very strong hand; standing against a dealer 7 wins the vast majority of the time, while hitting or doubling risks ruining a near-winning total.

Hard 18 against a dealer 6 is a strong standing position; the dealer is likely to bust, and hitting or doubling risks a made hand.

Hard 8 against a dealer 9 is a clear basic-strategy hit; doubling is too weak here since the dealer's 9 upcard is strong.

Hard 18 vs dealer 9: standing is basic strategy; hitting risks busting with most cards and gains little.

Hard 12 against a dealer 5 is a stand per basic strategy; the dealer's bust risk is high and hitting only risks busting with little gain.

Hard 11 against a dealer 10 is a textbook double in a 6-deck S17 game; the expected value of doubling exceeds hitting since many ten-value cards remain to make 21.

Soft 13 (A-2) against a dealer 5 is a classic double per basic strategy; the dealer's bust potential is high and I can't bust with one card.

Soft 20 (A-9) is a near-made hand; standing wins against a dealer 9 upcard, while hitting or doubling risks ruining a strong total.

A pair of 5s is played as hard 10; against a dealer 10, basic strategy says hit rather than double or split.

Hard 19 is a very strong hand; standing is clearly optimal against a dealer ten with no better options available.

Hard 13 against a dealer 5 is a standing situation per basic strategy; the dealer is likely to bust, and hitting risks breaking a strong position.

Hard 10 against a dealer 2 is a standard double per basic strategy; the dealer's weak upcard and my strong draw potential make maximizing the bet correct.

Hard 8 against a dealer 5 is a basic-strategy hit; doubling is reserved for 9-11, and standing on 8 gives up too much EV.

Hard 18 against a dealer 5 is a strong standing hand; hitting risks busting for negligible gain.

Hard 20 is a near-made hand; standing wins against a dealer 2 the vast majority of the time, while hitting or doubling would only risk destroying the hand.

Soft 15 against a dealer 2 is a clear hit per basic strategy; the ace gives flexibility and standing leaves a weak total that loses to most dealer outcomes.

Hard 15 against a dealer 2 is a standing hand per basic strategy; the dealer's bust risk with a low upcard outweighs the danger of hitting into a bust.

Hard 16 against a dealer 5 is a standing situation per basic strategy; the dealer's bust probability is high and hitting risks busting with 10-value cards abundant.

Hard 16 against a dealer 3 is a basic-strategy stand; the dealer's bust probability is high and hitting risks busting.
