Blackjack table

Hard 5 vs dealer 7 is far too weak to stand or double; hitting is clearly optimal.

Soft 16 (A-2-3) vs dealer 7 is a clear hit; the ace gives flexibility and standing on 16 loses to a likely dealer 17+. Doubling isn't legal with three cards.

Soft 18 vs dealer 7 is a stand per basic strategy; hitting only improves marginally and risks busting.

Hard 10 vs dealer ace is a clear hit; doubling is too risky against a likely strong dealer hand.

Hard 7 vs dealer 6 is far too low to stand; hitting is standard even against a weak upcard.

Hard 11 vs dealer 6 is a strong hit (double not allowed); hitting cannot bust and maximizes EV.

11 vs dealer 8 is a standard double in single-deck-like favorable counts; with 6 decks basic strategy says hit, but doubling 11 against 8 is close and aggressive. Actually basic strategy: hit 11 vs 8 in 6 decks.

Hard 16 vs dealer 9 is a losing hand if stood; basic strategy says hit.

Hard 19 vs dealer 4 is a clear stand; doubling risks a strong winning hand for minimal gain.

Hard 15 vs dealer 7 is a stand per basic strategy; hitting risks busting against a likely dealer 17.

Hard 20 vs dealer 3 is a clear stand; doubling or hitting risks a near-certain winning hand.

Hard 15 vs dealer 10 is a marginal hit per basic strategy, but with a 10 showing the risk of busting on a hit is high; standing keeps the dealer's ~10% bust chance working for me. Actually basic strategy says hit 15 vs 10, but the bust risk makes standing defensible here.

Hard 16 vs dealer 9 is a losing standing position; basic strategy says hit despite bust risk.

Hard 17 vs dealer 9 is a stand in basic strategy; hitting risks busting with little gain.

Hard 12 vs dealer 2 is a marginal basic strategy hit; standing gives up EV against the dealer's weak upcard.

20 is a strong standing hand; only a dealer 20/21 beats it, and hitting risks busting. Standing maximizes expected value.

20 vs dealer 10 is a clear stand; doubling or splitting would be EV-negative.

Hard 16 vs dealer 10 is a standard hit; standing loses more often than hitting.

11 vs dealer 4 is a standard double; strong expected value with dealer likely to bust.

Hard 10 vs dealer 10 is a hit per basic strategy; doubling is too risky against a strong upcard.

Hard 20 vs dealer 10 is a clear stand; hitting risks busting for negligible gain.

Hard 17 vs dealer 8: standing is standard; hitting risks busting a made hand.

Basic strategy for 4,4 vs dealer 5 is to hit; splitting 4s is inferior since 8 against a weak 5 favors drawing to a strong total.

Hard 12 vs dealer 5 is a stand in basic strategy; dealer bust risk is high.
