Blackjack table

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

Hard 13 against a dealer 8 is a losing standing position; basic strategy calls for a hit since the dealer likely makes 18.

Hard 20 is a near-certain winner; hitting risks an almost certain bust with no upside.

Basic strategy: never split 4s in multi-deck; with 8 vs dealer 4, hitting is correct since the dealer's 4 is not weak enough to justify doubling, and 8 is too low to stand.

Hard 18 against a dealer 4 is a clear stand per basic strategy; hitting risks busting a made hand with little upside.

Hard 20 against a dealer King is a near-lock; standing maximizes expected value and avoids risking a made hand.

Hard 11 against a dealer 7 is one of the strongest doubling spots; expected value is maximized by doubling rather than hitting.

Basic strategy for a hard 16 against a dealer 10 upcard is to hit; standing loses more often since the dealer likely finishes 17-20, and doubling a 16 is far too risky.

Hard 18 is a stand against a dealer 10 in basic strategy; hitting risks busting a made hand with little gain.

A hard 20 against a dealer 5 is nearly unbeatable; standing maximizes expected value, while splitting or doubling kings would only weaken a dominant hand.

Hard 13 against a dealer 6 is a stand per basic strategy; the dealer's high bust probability makes hitting unnecessary risk.

Hard 19 is a very strong hand; standing against a dealer 7 is clearly optimal, as hitting or doubling risks far more than the small edge from improving.

Hard 9 against a dealer King is a hit per basic strategy; doubling is only correct against dealer 2-6, and standing on 9 gives a near-certain loss if the dealer has a made hand.

Hard 12 against a dealer King is a losing hand if stood; basic strategy requires hitting against 7 or higher since the dealer likely makes 17+. Standing on 12 vs K gives roughly 33% win chance versus better odds drawing.

Hard 13 against a dealer 10 is a clear basic-strategy hit; standing loses against the dealer's likely 17-20, so I need to draw to improve.

Hard 15 against a dealer 10 is a losing hand if stood (~23% win chance); basic strategy says hit since surrender is unavailable.

Hard 18 against a dealer king is a clear stand; hitting risks busting with little chance of improvement.

Hard 13 against a dealer 3 is a stand per basic strategy; hitting risks busting while the dealer's weak upcard already gives favorable odds.

Hard 12 against a dealer 4 is a basic-strategy stand (hit only vs 2 or 3); with ~5 decks remaining the composition shift from J-2 is far too small to flip the play.

Hard 14 against a dealer 10 is a basic strategy hit; standing leaves the hand likely losing to dealer 20. Hitting minimizes expected loss.

Hard 10 against a dealer 10: basic strategy is to hit; doubling is only correct against dealer 2-9, and standing on 10 leaves me far too weak against a likely 20.

Hard 12 against a dealer 10 is a losing standing position; basic strategy calls for a hit since only a 10 busts me and standing loses ~2/3 of the time.

Hard 19 versus a dealer 10 is a strong standing hand; hitting risks busting for negligible gain. Standing is the correct basic strategy play.

Hard 14 against a dealer 5 is a basic-strategy stand: the dealer's high bust probability makes hitting riskier than letting the dealer break. No card history indicates a count favorable enough to deviate or double.

Hard 17 vs dealer 9 is a clear stand; hitting risks busting with no upside.

Hard 17 versus a dealer 10 is a standing hand per basic strategy; hitting risks busting against a likely dealer push or win with little upside.

Hard 19 against a dealer 5 is a strong standing hand; hitting or doubling risks turning a likely winner into a loss.
