Blackjack table

Hard 16 versus a dealer 6 is a basic strategy stand; the dealer busts often enough from a 6 that hitting is worse than standing.

Basic strategy: split 7s against a dealer 2 (split 7s vs 2-7), especially with DAS allowed.

Hard 17 against a dealer 2 is a clear stand per basic strategy; hitting risks busting with little upside.

Soft 18 (A-7) versus a dealer 2 is a basic strategy double when double after split is allowed; it maximizes expected value against a weak dealer upcard.

Hard 20 against a dealer 8 is a strong stand per basic strategy; splitting tens or doubling would lower expected value.

Hard 13 versus a dealer Ace is a hit per basic strategy; standing would be far worse since the dealer rarely busts with an Ace showing.

Hard 13 versus a dealer 10 is a hit per basic strategy, since standing on 13 against a strong upcard loses far more often than hitting.

Hard 12 versus a dealer 3 is a basic strategy hit; standing is slightly worse since the dealer busts less often with a 3 than with 4-6.

Hard 20 against a dealer 3 is a clear stand; hitting would almost certainly bust.

Hard 20 against a dealer 6; basic strategy says stand, never split tens.

Hard 20 against a dealer 4 is a strong hand; basic strategy says stand and never split tens.

Hard 15 against a dealer 10 with no surrender available: basic strategy says hit, since standing loses far more often than hitting.

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

Hard 13 versus dealer 5 is a basic strategy stand; the dealer is likely to bust and hitting risks busting our own hand.

Hard 15 vs dealer Ace with no surrender: basic strategy says hit, since standing loses far more often against a strong dealer upcard.

Hard 16 against a dealer Ace with no surrender; basic strategy says hit since standing loses far more often against a strong upcard.

Hard 12 vs dealer 6: basic strategy says stand, since the dealer's bust probability is high and hitting risks busting on any ten-value card.

Hard 8 against a dealer Ace cannot bust on the next card and basic strategy says hit any hard total of 8 or less.

Hard 18 against a dealer Ace: basic strategy says stand, since hitting busts far more often than it improves.

Hard 12 versus a dealer 6 is a basic strategy stand; the dealer busts often enough that hitting risks busting ourselves for little gain.
