Hearts Shoot-the-Moon Feasibility Check

Screen observed hearts/queen-spades allocation for arithmetic shoot-the-moon possibility, retaining unallocated cards; does not infer future trick control or authorize variant scoring.

Description

Hearts point evidence can show whether a player still has a possible or completed shoot-the-moon result.

Hearts point evidence can show whether a player still has a possible or completed shoot-the-moon result. Unknown queen ownership leaves points unassigned.^[1]

Enter four integer heart counts 0–13 totaling≤13, queen owner−1 or 0–3 and target player 0–3. Return target/others/remaining points and possibility when others have zero points.

When to use Hearts Shoot-the-Moon Feasibility Check

Use Hearts Shoot-the-Moon Feasibility Check when you need to evaluate the supplied records under the calculation and evidence rules below. No legal play, hand completion or match score adjustment is inferred.

Prepare the supplied game state, observations and explicit variant settings. Follow the card, board, coordinate and state conventions in the calculation rules.

How to use Hearts Shoot-the-Moon Feasibility Check and understand its results

Prepare the supplied game state, observations and explicit variant settings. Follow the card, board, coordinate and state conventions in the calculation rules.
Enter targetPlayerIndex, heartsCapturedByPlayers, queenSpadesCapturedByPlayer using the field table and calculation rules, then run the tool.
Read targetCapturedPenaltyPoints, opponentsCapturedPenaltyPoints, unallocatedPenaltyPoints, shootMoonStillArithmeticallyPossible, allMoonPenaltyCardsObservedCaptured. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
targetPlayerIndex	Target player index	number	Required
heartsCapturedByPlayers	Hearts captured by players	list of number	Required
queenSpadesCapturedByPlayer	Queen spades captured by player	number	Required

Enter four integer heart counts 0–13 totaling≤13, queen owner−1 or 0–3 and target player 0–3. Return target/others/remaining points and possibility when others have zero points.

playerPoints=hearts+13 if queen owner; moonComplete=targetPoints26

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
targetCapturedPenaltyPoints	Target captured penalty points	number
opponentsCapturedPenaltyPoints	Opponents captured penalty points	number
unallocatedPenaltyPoints	Unallocated penalty points	number

Limitations and assumptions

No legal play, hand completion or match score adjustment is inferred.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.

Alternative or Complementary methods

Use Spades Books & Bid Check: Spades contract scoring distinguishes a made bid, failed bid and overtrick bags. Caller rates define the scoring variant. For a complementary task, use Euchre Trump Trick Power Rank: Euchre bowers change both rank and effective suit. The same-color off-suit jack becomes trump for comparison.
