Blackjack table

Hard 11 versus dealer 6 is a standard double in basic strategy; the dealer's weak upcard and high chance of drawing a ten make doubling the maximum-EV play.

Hard 17 against a dealer 5 is a clear stand per basic strategy; the dealer is likely to bust and hitting risks busting our own hand.

Hard 12 versus a dealer 8 is a hit in basic strategy; standing loses far more often since the dealer makes a strong hand frequently from an 8.

Soft 19 against a dealer 10 is a stand per basic strategy; hitting or doubling lowers expected value.

Hard 16 versus a dealer 10 with no surrender available: basic strategy says hit, as standing loses more often than hitting in the long run.

Hard 10 versus dealer 8 is a standard double down in basic strategy for a 6-deck S17 game.

Hard 20 versus a dealer 5 is a strong standing hand; basic strategy never splits tens, so stand.

Hard 13 against a dealer Ace: basic strategy says hit, since the dealer makes a strong hand too often to stand on 13.

Hard 13 against a dealer 7 is a hit under basic strategy since the dealer is likely to make a strong hand; standing on 13 loses too often.

Hard 16 versus a dealer 7 is a hit by basic strategy since the dealer makes a hand too often to stand on 16; no surrender available.

Hard 18 against a dealer 7 is a clear stand per basic strategy; hitting risks busting a strong hand.

Pair of aces against a dealer 6 is always a split in basic strategy; two hands starting with an ace have far higher expected value than soft 12.

Hard 17 versus a dealer 10 is a stand per basic strategy; hitting busts too often and doubling is far worse.

Hard 12 versus dealer 6 is a stand in basic strategy; the dealer busts often enough that taking a card (31% bust chance) is worse.

Hard 10 vs dealer 7 is a standard double in basic strategy for a 6-deck S17 game.

Soft 14 against a dealer 10 is a basic strategy hit; doubling is only correct against weak dealer upcards (5-6).

Hard 20 against a dealer ten; standing is clearly correct as any hit almost certainly busts.

Hard 12 versus a dealer 2 is a basic strategy hit; standing is slightly worse in EV and doubling is clearly negative.

Hard 15 versus a dealer 2 is a stand in basic strategy; the dealer busts often enough from a 2 that hitting a stiff hand loses more than standing.
