With a total of 11 against a dealer 4, doubling down is the optimal basic strategy play to maximize expected value.

Soft 14 vs dealer 3 is not strong enough to double; hitting improves the hand while preserving the option to improve further.

Hard 14 is a stand against a dealer 3 under basic strategy, since the dealer is likely to bust or make a hand below 17.

With a hard 16 against a dealer 5, the dealer is likely to bust, so standing is the optimal play.

Hard 9 is too weak to stand and doubling against a dealer 8 is not profitable, so hitting gives the best chance to improve.

Hard 13 against a dealer 8 is a losing hand if I stand, so I take a hit to try to improve to 17 or better.

With a hard 15 against a dealer 8, hitting gives a better chance to improve than standing, since the dealer is unlikely to bust from 8.

Standing on hard 13 against a dealer 4 is correct because the dealer is likely to bust with a 4 upcard, and hitting risks improving a made hand unnecessarily.

With a hard 13 against a dealer 5, the dealer is likely to bust, so standing is the correct basic strategy play.

With a hard 10 against a dealer Ace, basic strategy favors hitting rather than doubling because the Ace is a strong upcard and doubling risks too much on a marginal hand.

Hard 19 is strong against an Ace; hitting risks busting with little upside, so standing is correct.

With a hard 20 against a dealer 6, standing maximizes win probability since only 21 or dealer busts can beat this strong hand.

Dealer upcard 5 is a bust card, so standing on 15 is the basic strategy play to avoid busting.

Hard 19 is strong against a dealer Ace; hitting risks busting and doubling is not profitable, so standing is the correct basic strategy.

With a pair of 4s against dealer 2, basic strategy recommends hitting rather than splitting or doubling, as the hand total is only 8 and splitting 4s is not advantageous.

Total 17 is strong against a dealer 2, and hitting risks busting with little upside.

Soft 17 is a strong doubling hand against a dealer 4 upcard, and the dealer stands on soft 17, improving the value of doubling.

Splitting 7s against a dealer 7 is the basic strategy play, creating two strong hands against a likely stiff dealer total.

With a hard 9 against a dealer 7, doubling is not profitable; hitting gives the best chance to improve the hand.

Hard 19 is a strong hand against a dealer 7, so standing maximizes expected value.

Soft 18 against a dealer 7 is a standing hand in basic strategy, especially with dealer standing on soft 17. Doubling risks too much against a strong upcard.

Hard 9 against a dealer 2 is a hit in basic strategy, since doubling is only profitable against dealer 3-6.

Hard 19 is a strong made hand against a dealer 2, and hitting risks busting with no meaningful gain. Standing is the correct basic strategy play.

With a total of 10 against a dealer 2, hitting is the best play to improve the hand, as doubling is less favorable with a 10 total against a low upcard.

Standing on 17 against a dealer 2 avoids the high risk of busting, and the dealer must draw to at least 17, giving a reasonable chance to push or lose without me risking chips.

With 18 against dealer's 5, standing is the optimal play; hitting risks busting and doubling is unnecessary.

Dealer shows a 6, a bust card, so standing on 16 is the correct basic strategy play.

Hard 17 is a made hand and hitting risks busting against a dealer 10 upcard. Standing is the correct basic strategy play.
