Blackjack table

Hard 10 against a dealer 10 is a hitting hand; doubling is not favorable here, so I hit to try to make 17-21.

Hard 17 against a dealer 10 is a standing hand under basic strategy; hitting risks busting with no meaningful improvement.

Pair of 5s totals 10; basic strategy says double against dealer upcard 5, never split 5s.

Hard 15 against dealer 6 is a standing hand under basic strategy; the dealer is likely to bust, and doubling would risk extra chips on a weak total.

Soft 19 against dealer's 3 is a strong standing hand; doubling would risk more chips for marginal gain, and standing maximizes expected value.

A pair of 8s should always be split, especially against a weak dealer upcard like 3, turning one poor 16 into two stronger starting hands.

Hard 15 against a dealer 3 is a standing hand in basic strategy; the dealer is likely to bust, and doubling would risk extra chips on a weak total.

Soft 19 against a dealer 3 is a strong standing hand; hitting risks busting or weakening a made total, and doubling is not justified by the dealer's weak upcard.

I have a hard 20 against the dealer's 2; standing is the clear play since hitting or doubling risks busting a near-certain winner and splitting 20 is unjustified.

Hard 15 versus dealer 2 is a standing hand in basic strategy; hitting risks busting, and doubling is not favorable here.

Hard 19 against a dealer 7 is a strong standing hand; hitting risks busting and doubling adds risk without improving the hand.

Hard 20 is a strong total, and standing preserves it against the dealer's king upcard rather than risking a bust or doubling into a likely strong dealer hand.

Hard 10 against a dealer 9 is a strong doubling opportunity, so I maximize value by doubling while the rules allow it.

Hard 20 against dealer 3 is a strong standing hand; splitting tens or doubling would be -EV, so stand.

Hard 19 against a dealer queen is a strong standing hand; hitting or doubling risks busting a near-made total.

Hard 15 against a dealer 10 is a losing stand; hitting maximizes equity by trying to reach 17-21 without busting too often.

Hard 17 against a dealer 10 is a standing hand; hitting risks busting with no equity gain.

With a hard 16 against the dealer's king, standing is the best play since hitting risks busting and doubling would only increase risk on a weak total.

Hard 17 against a dealer 8 is a standing hand; hitting risks busting and doubling would only add risk without improving the total.

With a hard 12 against the dealer's 7, basic strategy is to hit; standing risks losing to a likely made dealer hand, while doubling is not favorable here.
