Blackjack table

Basic strategy for 7,7 against a dealer ten is to stand, since splitting into two hands that each start on 7 against a ten is worse than keeping 14. Hitting is also worse than standing here, and the dealer has already peeked and has no blackjack.

Hard 11 against a dealer 10 is a close call in a 6-deck game where the dealer stands on soft 17. Basic strategy says to double, but hitting is the more conservative play. I'm choosing hit to stay in line with the chosen plan, though double has slightly higher expected value.

Hard 19 against a dealer 10 is a clear stand, since hitting risks busting with most cards and the dealer has no peeked blackjack.

Soft 18 against a dealer 4 is a standard double in basic strategy, and doubling is legal on any first two cards. Dealer stands on all 17s, but the 4 is still a weak upcard, so doubling has the best expected value.

Hard 13 against a dealer 10 is a basic strategy hit, since standing loses more often than hitting in the long run. Doubling is not favorable here.

Hard 17 against a dealer 2 is a standard stand, since hitting risks busting and doubling has negative expected value.

Hard 13 against a dealer 9 is basic strategy to hit, since standing loses more often than hitting and doubling isn't favorable.

Hard 19 against a dealer 9 is a clear stand; hitting risks busting with little chance of improving.

Soft 17 against a dealer ten is a hit in basic strategy, since standing on 17 loses more often than hitting and doubling is not favorable against a ten. Chat is off, so the table message is empty.

Soft 18 against a dealer 10 is a hit in basic strategy, since standing on 18 loses more often than the soft hand risks by drawing, and a hit can't bust a soft hand.

Hard 18 (6+A+A+10) against a dealer Queen: standing is correct, since hitting risks busting and 18 beats a dealer who ends on 17 or busts. Chat is off, so the message is empty.

Hard 12 against a dealer 7 is a basic strategy hit. Standing on 12 vs 7 is worse, and doubling is not recommended.

Hard 19 against a dealer 9 is a clear stand; hitting risks busting and doubling has negative expected value.

Hard 13 against a dealer 9 is a basic strategy hit; standing is only correct against dealer 2-6, and doubling is not favorable with 13.

Hard 6 against a dealer 7 is best played by hitting, since doubling on 6 is not favorable by basic strategy and standing is too weak.

Hard 15 against a dealer 7 is a hit under basic strategy, since the dealer is likely to make a hand of 17 or better and standing loses more often than hitting.

Hard 8 against a dealer 10 is a basic strategy hit; doubling is not favorable against a ten, and standing on 8 is too weak.

Hard 10 against a dealer 6 is a strong doubling spot under basic strategy, since the dealer is likely to bust and a ten-value card gives me 20.

Hard 20 against a dealer ten is a strong hand; standing is correct, and splitting tens is worse in expectation.

Hard 7 against a dealer 5 is too weak to double under basic strategy, since doubling on hard 7 is not recommended, so hitting is the standard play.

Hard 17 against a dealer 5 is a clear stand, since the dealer is likely to bust and hitting risks busting with a strong total.

Hard 15 against a dealer 4 is a standard stand, since the dealer busts often with a weak upcard and hitting risks busting the player.

Basic strategy for 3,3 against a dealer 8 is to hit, since splitting 3s only applies against dealer 4-7 (with DAS, 2-7). Against an 8, hitting is better than splitting.
