Blackjack table

11 against dealer 8 is a standard hit (double is too risky vs 8); any ten gives 21 and small cards improve the hand.

Hard 12 vs dealer 8 is a losing standing hand; basic strategy says hit.

Hard 15 against a dealer 8 is a basic-strategy hit; standing leaves the hand too weak against a likely dealer 18.

Hard 13 vs dealer 8 is a standard hit; standing loses against strong upcards.

Hard 18 against a dealer 8 is a clear stand per basic strategy; hitting risks busting a made hand with little gain.

I hold 20 versus a dealer 7 — standing is clearly optimal; doubling or hitting would only risk a near-certain win.

Hard 11 against a dealer 10 is a standard basic-strategy double in 6-deck, S17 games; the expected value of doubling exceeds hitting here.

Hard 14 against a dealer 10 (Queen) is a basic-strategy hit; standing loses too often since the dealer likely makes 17-20, and doubling is not viable at 14.

Hard 19 vs dealer Q is a clear stand; only a 2 gives the dealer a chance, and 19 wins most of the time.

Hard 14 against a dealer 6 is a basic-strategy stand: the dealer's bust probability is high and hitting risks busting with any card 8 or higher.

Hard 16 against a dealer 10-value upcard is a basic-strategy hit; standing loses more often than drawing one card, and surrender is unavailable.

Hard 20 against a dealer 9 is a near-certain winner; standing is optimal since hitting risks busting and splitting tens destroys a made hand.

Hard 20 is a near-made hand; standing is clearly optimal against a dealer 6, which carries high bust risk. Doubling or splitting would only risk a dominant position.

Hard 20 is a near-made hand; standing against a dealer 7 maximizes EV, since only a tiny chance of dealer 21 beats it and hitting risks a certain win.

Hard 19 is a very strong hand; standing against a dealer 5 is clearly optimal since any hit risks busting a near-certain winner.

Hard 8 vs dealer 7 is a clear hit; double is not warranted with only 8.

Hard 12 against a dealer 7 is a basic-strategy hit: the dealer likely makes 17-20, and standing on 12 wins only if the dealer busts. Drawing one card carries low bust risk.

Hard 13 against a dealer 7 cannot win by standing since the dealer likely holds 17; basic strategy is to hit 13-16 against 7-A and take the bust risk.

Hard 16 against a dealer 10 is a basic-strategy hit; standing only wins if the dealer busts, while hitting gives a real chance to improve despite bust risk.

Hard 12 against a dealer 5 is a standing hand in basic strategy; the dealer's high bust probability makes hitting unnecessary risk.

Hard 13 against a dealer 8 is a clear basic-strategy hit; standing only wins if the dealer busts, and 8-up busts too rarely to justify it.

Hard 20 against a dealer 4 is a near-certain winner; standing is clearly optimal. Doubling or splitting tens would only reduce expected value.

Hard 11 against a dealer 10 is a standard double in 6-deck, S17 basic strategy; the dealer has already peeked, so there is no blackjack risk. Doubling maximizes expected value on this strong total.

Hard 18 against a dealer 2 is a clear stand in basic strategy; hitting risks busting for minimal expected gain, and doubling is not justified against a weak but non-bust upcard.

Basic strategy for a pair of 9s calls for splitting against a dealer 4; two 9s into fresh hands have higher expected value than standing on hard 18 here.

Hard 16 vs dealer 4 is a basic-strategy stand; the dealer's 4 upcard carries high bust risk, and doubling a weak 16 would only increase exposure.

Soft 20 (A-9) is nearly unbeatable; hitting risks turning a 20 into a worse hand, and doubling is far too risky. Standing against a dealer 4 maximizes expected value.

Hard 20 versus a dealer queen is a near-certain winner; hitting or splitting would only risk a made hand. Standing maximizes expected chips.
