Hard 7 vs dealer 10 is a clear basic-strategy hit; doubling or standing would be far too weak here.

Hard 15 against a dealer 10-value upcard is a basic-strategy hit; standing loses to most dealer made hands, and no surrender is available.

Pair of aces is always split; dealer 2 weak, resplit odds good.

Hard 13 against a dealer 5 is a standing situation in basic strategy; the dealer's bust probability is high and hitting risks busting with 10-value cards frequent.

Hard 6 against a dealer 8 is a clear hit; even with double-after-split allowed, splitting 3s against an 8 is not profitable, so I take one card and reassess.

Hard 14 vs 8 is a close call, but basic strategy favors standing against a dealer 8 upcard with no surrender available.

Hard 12 against a dealer 9 is a clear basic-strategy hit: standing loses far more often, and doubling or splitting 6s against a 9 has negative expectation.

Hard 19 is a strong standing hand against a dealer 4; hitting or doubling would only risk ruining a near-winning total.

Hard 19 is a strong made hand; standing is clearly optimal against a dealer J, as hitting risks busting a near-winning total.

Soft 16 vs dealer 10 is a clear hit per basic strategy; doubling is too risky against a likely dealer ten, and standing leaves almost no chance to improve.

Hard 16 (A-5-10) against a dealer 10 is a basic-strategy hit; standing loses against the dealer's likely 20 unless they bust, and hitting catches the 9,10,A cards that improve the hand.

Hard 15 vs dealer 9 is a losing spot either way; basic strategy says hit since standing loses more against the dealer's likely 19.

Hard 20 is a near-lock; standing maximizes expected value against a dealer 9. Hitting risks busting for negligible gain.

Hard 15 against a dealer 8 is a clear basic-strategy hit; standing loses too often since the dealer likely makes 18+. No surrender is available, so hitting minimizes expected loss.

Hard 20 is a made hand; standing is clearly optimal against a dealer 8. Hitting risks busting with virtually no upside.

Hard 20 is a near-made hand; standing maximizes EV against a dealer 2 upcard. Hitting or doubling risks ruining a winning total.

Hard 20 is a near-unbeatable hand; standing is clearly optimal against a dealer 2, with no value in risking a hit, double, or split.

Hard 12 against a dealer 10 is a clear hit per basic strategy; standing loses too often and doubling is far too risky.

Hard 17 vs dealer 10 is a standard stand; hitting risks busting with little gain since only 2-4 improve the hand.

Hard 19 vs dealer 6 is a clear stand; dealer 6 is a weak upcard with high bust frequency, and doubling 19 would risk a strong winning hand.

Soft 13 vs dealer 6 is a standard double: the ace can't bust with one card and the dealer's 6 upcard busts frequently, maximizing expected value versus hitting.

Hard 20 is a near-made hand; standing wins against most dealer outcomes and splitting tens sacrifices a strong total.

Basic strategy: hard 17 vs dealer 7 stands; hitting only risks busting with little gain.

Hard 16 against dealer 6 is a standard stand; dealer likely busts, and hitting risks busting.

Soft 17 (A-6) cannot bust on one hit and is too weak to stand against a dealer 8; basic strategy says hit, not double.

Hard 17 is a standing hand against a dealer 8; hitting risks busting with no meaningful gain.
