Blackjack table

Pair of 2s is only split against dealer 2-7 even with double-after-split allowed; against an 8 the expected value favors hitting the hard 4.

Hard 13 vs dealer 8 is a basic-strategy hit; standing only wins if the dealer busts, while hitting improves expected value against a likely dealer 18.

Hard 15 against a dealer 8 is a losing spot either way, but standing keeps bust risk off the table and lets the dealer's stiff draw do the work. Hitting only improves things if I catch 6 or less, so the stand is the standard play.

Hard 17 against a dealer 9: standing is basic strategy since hitting risks busting for minimal gain, and doubling is far too risky.

Hard 16 against a dealer 6 is a classic stand: the dealer's bust probability is high and hitting risks busting. Basic strategy favors standing here.

Hard 6 against a dealer 8 is far below the needed range; basic strategy says hit, and doubling a 6 is not profitable.

Hard 14 against a dealer 8 is a basic-strategy hit; standing loses too often since the dealer likely makes 18+. Only hit or stand are legal here.

Hard 11 vs dealer 9 is a textbook double: one card likely makes 19-21, and doubling maximizes EV in this favorable spot.

Hard 20 is a made hand; standing wins against dealer 9 in nearly all cases, and any other action risks ruining the hand.

Hard 10 against a dealer 2 upcard is a standard doubling spot in multi-deck basic strategy (S17), with doubling holding higher expected value than hitting.

Hard 20 is a near-winning hand; standing is overwhelmingly optimal against a dealer 8. Splitting or doubling would only risk a strong position.

Soft 15 against an Ace is a clear hit; dealer is strong and I can't bust with one card.

Soft 19 is a strong made hand; basic strategy says stand against a dealer Ace, especially since the dealer has already peeked and does not have blackjack. Hitting risks turning a likely winner into a bust.

Soft 17 (A-5): basic strategy says hit against a dealer 8; standing risks losing to a likely 18-20. Double is not recommended against an 8.

Soft 18 against a dealer 8 is a losing standing position; basic strategy says hit to improve, since I can't bust with one card.

Soft 19 vs dealer 8 is a stand in basic strategy; hitting can only risk a strong hand.

Hard 12 against a dealer 8 is a losing stand; basic strategy says hit to try to improve.

Hard 14 against a dealer 8 is a basic-strategy hit; standing risks losing to a likely dealer 18, while drawing one card has low bust risk.

Hard 14 against a dealer 8 is a clear basic-strategy hit; standing loses more often than drawing one card. Doubling is not justified with a mediocre total.

Hard 20 is a made hand; standing maximizes expected value against any dealer upcard.

Hard 12 against a dealer 10 is a basic-strategy hit; standing loses more often than drawing, and doubling is too risky against a likely dealer 20.

Hard 8 against a dealer 5 is too weak to double; basic strategy says hit to improve toward a strong total while the dealer is likely to bust.

Hard 18 against a dealer 5 is a clear stand; hitting risks busting a made hand while the dealer is likely to bust. Standing maximizes expected value here.

Basic strategy: stand on hard 16 against a dealer 5, since the dealer is likely to bust.

Hard 16 vs dealer 10 is a basic-strategy hit (surrender unavailable); standing loses more often than taking one card.

Hard 19 is a very strong hand; only a dealer 20/21 beats it, and hitting risks busting with 10+ cards worth of danger. Standing maximizes expected value.

Hard 15 vs dealer 7 is a stand per basic strategy; hitting risks busting with only marginal gain.
