Blackjack table

Pair of 5s plays as hard 10; basic strategy doubles against a dealer 2 since one more card gives a strong 20/19 and the dealer is weak.

Hard 20 against a dealer J is a near-certain winner; hitting or doubling risks busting a premium hand for negligible gain.

Hard 16 against a dealer 10 is a losing standing position; basic strategy says hit, taking one card and hoping for 17-21.

Hard 16 against a dealer 4 is a stand per basic strategy; the dealer's bust probability is high and hitting risks busting with 10-value cards abundant.

Soft 14 against a dealer 10 is a clear hit per basic strategy; the ace gives a free draw with no bust risk, and standing leaves a very weak total.

Soft 19 vs dealer 10 is a stand per basic strategy; hitting risks busting with little gain.

Soft 16 against a dealer Ace is a clear basic-strategy hit; doubling is only correct against weak upcards like 4-6.

Hard 16 against a dealer Ace is one of the worst standing spots; with no surrender available, hitting minimizes expected loss despite high bust risk.

Hard 15 against a dealer ace is a strong loser; with no surrender available, basic strategy says hit since standing loses to the ace's high made-hand frequency.

Hard 9 against a dealer 7 is a clear hit per basic strategy; drawing a 10 gives 19 while standing on 9 loses to the dealer's likely 17-20.

Hard 19 is a very strong hand; standing wins against a dealer 7 in the vast majority of outcomes, while hitting risks busting for negligible gain.

Basic strategy: with 9,9 against a dealer 10, standing on hard 18 is correct; splitting into two hands against a strong upcard loses more on average.

Hard 18 against a dealer queen is a strong standing hand; hitting risks busting for negligible gain, and doubling is far too risky.

Hard 16 against a dealer 8 is a losing standing position; basic strategy calls for a hit since the dealer's expected total beats 16 too often.

Basic strategy: hard 18 vs dealer 10 is a marginal loser standing (dealer 10 makes 18 only ~55% likely to win), so hitting is slightly better despite bust risk.

Hard 14 against a dealer 10 is a clear basic-strategy hit; standing loses to any dealer 17+ and doubling risks busting on 8+.

Hard 7 vs dealer 8 is far below 17; hitting is clearly correct and doubling is too weak.

Soft 18 against a dealer 8 is a stand per basic strategy; hitting risks busting with little gain since dealer 8 only wins against 19+.

Soft 14 against a dealer 7 is a clear hit per basic strategy; the ace gives flexibility and standing leaves a weak total that loses unless the dealer busts.

Soft 16 vs dealer 7 is a clear hit per basic strategy; the ace gives a free redraw with no bust risk on one card, and standing loses to the dealer's likely 17-20.

Hard 16 against a dealer 7 is a basic-strategy hit: the dealer makes 17-21 often enough that standing loses more than hitting, and busting still loses only one bet.

Hard 17 against a dealer 7 is a stand per basic strategy; hitting risks busting with no upside since dealer 7 only pushes or beats me if they make 17-21 anyway.

Hard 15 against a dealer 9 is a clear hit per basic strategy; standing loses to the dealer's likely 19, and only a 6-9 busts me.

Hard 7 against a dealer 9 is far too weak to stand or double; basic strategy is to hit and try to build a competitive total.

Hard 17 is above the hitting threshold in basic strategy; hitting risks busting with no meaningful gain against a dealer 9.
