Blackjack table

Basic strategy for a pair of 2s against a dealer 10 (Q) is to hit, not split, since splitting against a 10 loses more money.

Hard 8 against a dealer 10 is a clear hit under basic strategy; no bust risk on the next card.

Hard 11 against a dealer 10 is a clear hit (double isn't available with four cards); standing on 11 is never correct.

Soft 15 (A,4) against a dealer Ace: basic strategy says hit, since doubling is only correct against dealer 4-6 and standing on 15 is far too weak.

Soft 17 against a dealer Ace is always a hit per basic strategy; standing on 17 vs Ace is a losing position and hitting cannot bust.

Hard 17 versus dealer Ace: basic strategy says stand, since hitting a hard 17 busts too often.

Hard 10 against a dealer 6 is a standard double down in basic strategy; the dealer is weak and we have a strong chance to make 20 with one card.

Hard 17 against a dealer 3 is a clear stand under basic strategy; hitting risks busting with little upside.

Hard 15 against a dealer 7 is a basic strategy hit; standing loses more often since the dealer makes a hand frequently from a 7.

Hard 10 versus a dealer ten: basic strategy says hit, not double, since the dealer's strong upcard makes doubling unprofitable.

Hard 19 against a dealer 10 is a clear stand per basic strategy; hitting would bust most of the time.

Hard 13 against a dealer 2 is a basic strategy stand; the dealer busts often enough that hitting a stiff hand loses more in expectation.

Hard 20 versus a dealer ten; basic strategy says stand, and splitting tens is a clear EV loss.

Hard 7 vs dealer 4: basic strategy is to hit; doubling is not favorable with a hard 7.

Hard 12 versus a dealer 4 is a basic-strategy stand; the dealer busts often enough with a 4 up that standing beats hitting.

Hard 6 against a dealer King: basic strategy says hit; doubling is far too weak here.

Hard 8 against a dealer 10 is an obvious hit; no bust risk and standing on 8 is hopeless.

Hard 13 versus a dealer 10 is a basic strategy hit; standing loses far more often since the dealer makes a hand ~77% of the time.

Hard 17 against a dealer 9: basic strategy says stand, as hitting busts too often and standing yields better expectation.

Hard 18 versus a dealer 5 is a clear stand per basic strategy; the dealer is likely to bust and hitting risks busting a strong hand.

Hard 19 against a dealer King; basic strategy says stand on hard 17+.
