Blackjack table

Hard 16 against a dealer 8 is a losing stand, so hitting gives the best chance to improve without busting.

Hard 13 against a dealer 8 is a losing stand (dealer likely makes 17+), so I hit per basic strategy; doubling on 13 is not justified.

Hard 15 against a dealer 8 is a losing stand, so I hit to maximize the chance of reaching 17–21.

A pair of 8s is a mandatory split against any dealer upcard, including a 10; splitting avoids the weak 16 and improves long-run equity.

Soft 19 against a dealer 10 is a strong standing hand; hitting risks busting or weakening a made total, and doubling is not favorable here.

Hard 18 against a dealer 10 is a standing hand; hitting or doubling would risk busting or adding chips with poor expected value.

Hard 12 against a dealer 2 is a basic-strategy hit; standing is too passive and doubling is unfavorable with a weak total.

Hard 14 against a dealer 2 is a standing hand under basic strategy; hitting risks busting when the dealer is in a weak upcard range.

Hard 20 against a dealer 10 is a strong standing hand; hitting, doubling, or splitting tens would only reduce expected value.

Hard 17 against a dealer Ace is a standing hand, especially since the dealer has already peeked and does not have blackjack. Doubling would add risk without improving a made total of 17.

With a hard 14 against the dealer's 6, the dealer is in a bust-prone position, so standing is the optimal basic-strategy play rather than risking a hit or double.

Hard 13 against a dealer 4 is a standing hand in basic strategy; the dealer is likely to bust, so hitting risks busting unnecessarily.

Hard 13 against dealer 4 is a standing hand under basic strategy; hitting risks busting when the dealer is in a bust-prone upcard range.

Hard 15 against a dealer queen is a losing stand, so I hit per basic strategy; doubling is not correct for a hard 15.

Hard 16 against a dealer 5 is a standing hand under basic strategy because the dealer is likely to bust; doubling would risk extra chips on a weak total.

Hard 13 against a dealer Ace is a hitting situation because the dealer is likely to make 17 or better, so standing has poor expected value.

Soft 19 vs dealer J is a strong standing hand; the dealer peeked for blackjack and did not have it, so I keep 19 and avoid risking the hand.

Hard 14 against a dealer 4 is a standing hand in basic strategy; the dealer is likely to bust, so hitting risks busting unnecessarily.

Hard 12 against a dealer Ace is a hitting hand; standing is too weak, and doubling is not justified with 12.

Hard 19 is a strong standing hand; dealer's Ace upcard has already been peeked without blackjack, and hitting risks busting with no benefit.

Hard 6 against a dealer Ace is a clear hit; standing or doubling would be far too weak given the dealer's strong upcard.

Hard 16 against an Ace is a losing stand, so I hit to try to improve to 17-21 and avoid busting out against the dealer's likely strong total.

Hard 12 against a dealer 10 is a clear hit; standing risks losing to any dealer made hand, and doubling is not appropriate for this total.

Hard 13 against a dealer king is a losing stand; basic strategy calls for a hit since the dealer is very likely to make 17-21.

Hard 18 against a dealer king is a standing hand; hitting risks busting with any card above 3.
