Blackjack table

Hard 5 against a dealer 7 is a basic strategy hit; the hand is too weak to double and too weak to stand.

Soft 16 against a dealer 7 is a clear hit in basic strategy, since the hand can't bust on one card and standing on 16 is weak against a likely dealer total of 17 or better.

Soft 18 (2,3,A,2) against a dealer 7: basic strategy says stand with soft 18 vs 7, since the dealer stands on all 17s and soft 18 beats 17. Correction: stand is the better play here.}

The hand totals soft 20 against a dealer 7, which is a clear stand since hitting risks wrecking a very strong total. (The card list looks odd, with a repeated 2c, but the reported total is 20.)

Always split aces; a pair of aces is much stronger as two separate hands, even against a dealer 8.

Hard 14 against a dealer 5 is a standard stand, since the dealer busts often with a weak upcard and doubling on 14 is not favorable.

Hard 14 against a dealer ten is a basic strategy hit, since standing loses more often than hitting. The dealer has already checked for blackjack, so the Kc is not hiding an ace.

Hard 15 against a dealer 7 is a hit under basic strategy, since the dealer likely has a made hand of 17 and standing wins too rarely. Doubling is not recommended with a hard 15.

Hard 12 against a dealer 6 is a basic strategy stand, since the dealer busts often and hitting risks busting first.

Hard 15 against a dealer 7 is a hit in basic strategy, since standing on 15 loses to a likely dealer 17 and doubling is not recommended.

Hard 12 against a dealer ten is a hit by basic strategy; standing leaves too many losing outcomes, and doubling is not advisable.

Hard 15 against a dealer ten is a losing spot either way, but with no surrender, basic strategy says hit (EV about -0.54 vs about -0.54 for standing, hitting is marginally better in a 6-deck game). Doubling would be worse.

Hard 19 against a dealer 7 is a clear stand; hitting risks busting and doubling has negative expected value.

Basic strategy says to hit a hard 12 against a dealer 2, since standing leaves too many losing outcomes and the bust risk of hitting is acceptable.

Hard 20 against a dealer 7 is a strong hand, and splitting tens is worse than standing on 20 in basic strategy.

A hard 20 against a dealer ten is a strong made hand, so standing is correct. Splitting tens is worse in expectation, and chat is off so the message is empty.

Hard 16 against a dealer 10 with no surrender: basic strategy says hit, since standing loses slightly more in expectation. Doubling is clearly wrong here.

Hard 11 against a dealer 4 is a strong doubling spot, since the dealer is likely to bust or finish weak and any ten-value card gives me 21.

Hard 10 vs dealer ten: basic strategy says hit rather than double, since the dealer has already peeked and the double's expected value is lower against a ten.

Hard 20 is a very strong hand against a dealer ten; hitting would almost certainly bust or worsen it, so standing is correct.

Hard 17 against a dealer 8 is a stand under basic strategy; hitting risks busting too often and doubling is clearly wrong.
