queen
Enable an AI agent to recognise a queen chess piece, assess its physical and game status, and determine permitted handling or play, provisionally interpreting this undefined registry entry as a physical chess object.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a queen chess piece, assess its physical and game status, and determine permitted handling or play, provisionally interpreting this undefined registry entry as a physical chess object.
The most powerful standard chessman: a sliding piece that may move any number of unoccupied squares along its rank, file or diagonal (combining the rook's orthogonal and the bishop's diagonal powers), of which each side begins with one, placed beside its king on d1 (White) or d8 (Black).
It can be Identify a queen using the set convention and recorded game designation.; Associate the queen with a side, square and participation status.; Evaluate proposed queen moves and captures against the board state and declared rules.; Move or remove the physical queen when the corresponding game action is authorised.; Designate or replace a promotion representation while preserving the recorded game role.; Flag ambiguous or damaged queen representations for clarification or replacement..
Distinguishing features
The set's identification convention or an explicit game designation identifies the piece as a queen; a crown-like silhouette alone is insufficient.
Under standard chess rules, its movement combines unobstructed rank, file and diagonal travel, distinguishing its capabilities from those of a rook or bishop.
Its designation distinguishes it from a king even where their physical forms are similar; being tall or centrally placed does not establish queen identity.
A substitute object represents a queen only when its designation is established for the game; its original shape may identify a different piece.
Queen identity does not establish side affiliation, current board occupancy or whether the piece is still participating in play.
Scope
+ Evidence that a physical piece represents a queen within its chess set
+ Side affiliation and queen designation, including designation acquired through promotion
+ Physical condition affecting recognition, placement and handling
+ Position and participation status within a particular game
+ Queen movement and capture capabilities under the declared rules
- A human monarch and the office or title of queen
- A reproductive queen in a social insect colony
- Queen playing cards and other non-chess uses of the name
- The complete chessboard, game history and adjudication system
- Player identity, skill and strategic objectives
Characteristics
- Queen identification basis
- set convention | explicit designation | promotion record | uncertain Prevents appearance or expected starting position from being treated as conclusive identity.
- Physical representation
- dedicated queen piece | substitute piece | improvised token | unresolved Separates what the object looks like from the role it represents in play.
- Side affiliation
- reference to a side in the associated game, or unassigned Determines friendly and opposing occupancy without assuming literal white or black material.
- Game association
- reference to a game and its declared rules, or no active game Provides the context required to interpret position and permitted actions.
- Queen designation origin
- initial setup | promotion | custom setup | unknown Explains additional queens and distinguishes game-role continuity from physical-object continuity.
- Participation status
- active on board | captured | spare | awaiting placement | disputed Prevents an available physical queen from being mistaken for an active game piece.
- Current square
- reference to a square on the associated board, or not on board Anchors movement, capture and occupancy checks.
- Recognition condition
- unambiguous | damaged identifying features | visually ambiguous | designation required Determines whether the agent can identify the queen reliably before acting.
- Placement condition
- stable | unstable | broken | untested Determines whether the piece can remain clearly positioned on its square.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 9 layers · 16 findings · 24 questions.
Queen identity Establishes why this physical object is treated as a queen.
Queen identity depends on a set convention or game designation, particularly when pieces are stylised or substituted.
Set recognition
Interprets the identifying features used by this chess set.
Queen identification evidence
Record the evidence distinguishing the queen from the king and other pieces in this set.
- Which features or set instructions identify this object as a queen? definition
- What evidence resolves a possible confusion with the king or another similarly shaped piece? boundary
Assigned representation
Separates the object's physical form from its assigned chess role.
Queen designation
Record whether the object is a dedicated queen or has explicitly been assigned to represent one.
- Does this object represent a queen by its set identity or by an explicit designation? definition
- Who or what established a substitute object's queen designation, and where is that designation recorded? provenance
Game role and continuity Connects the queen to a side and tracks how its role arose.
A game can contain promoted queens, and replacing a physical representation must not create or erase a game piece.
Side and origin
Identifies the queen's affiliation and entry into the position.
Queen role origin
Record the associated side and whether the queen entered through setup or promotion.
- Which side does this queen belong to in the associated game? definition
- Was this queen established by the initial position, a promotion or a custom setup? provenance
Representation continuity
Preserves the identity of the game piece across changes of physical representation.
Promotion and replacement link
Connect a queen role to its promotion event or replacement object without conflating the participating objects.
- If this queen resulted from promotion, which recorded event established that role? provenance
- If the physical queen is replaced, what record preserves its side, square and participation status? action
Queen position and play Determines whether the queen participates in the position and what chess actions it can perform.
Queen movement capabilities alone do not establish move legality; occupancy, turn and king safety must be supplied by the game context.
Position membership
Distinguishes an active queen from captured pieces and available spares.
Active queen location
Record the queen's board square or its off-board status within the associated game.
- Is this queen active, captured, spare or awaiting placement? definition
- Which square does the game record assign to it, and does physical observation agree? measurement
Move and capture assessment
Applies queen-specific movement rules within the complete game position.
Permitted queen action
Assess a proposed move using the declared rules, line of travel, destination occupancy and game-level legality.
- Under the declared rules, does the destination lie along an allowed queen movement line with no intervening obstruction? action
- Do destination occupancy, the side to move and king-safety constraints permit this move or capture? action
Physical queen usability Assesses whether the queen can be recognised, placed and manipulated reliably during play.
A physically present queen may be unusable because damage obscures its identity or prevents stable, unambiguous placement.
Recognition and placement condition
Examines defects that interfere with identifying or positioning the queen.
Usable queen representation
Record damage or ambiguity affecting queen recognition, side recognition or stable occupancy of one square.
- Can this queen and its side still be distinguished from the other pieces after any damage or wear? boundary
- Can the object stand stably within its intended square without obscuring neighbouring occupancy? measurement
Handling and substitution
Supports physical execution of queen actions and replacement of unsuitable representations.
Queen handling plan
Determine how to manipulate or replace this queen while keeping the physical position aligned with the game record.
- Where can this queen be grasped and placed without damaging identifying features or displacing adjacent pieces? action
- If this representation is unusable, what replacement and designation procedure does the game context permit? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Real-world use
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Over-the-board play: each side's unique starting queen on d1 or d8, moved by sliding and capturing on the destination square
- Promotion: a pawn reaching the furthest rank is almost always exchanged for a queen; tournament kits carry spare queens for this
- Game records: moves written Qe4, Qxd5, Qh4+ and similar in algebraic notation, and stored in PGN
- Digital play and publishing: Unicode figurines and engine/GUI piece sets representing the same role
- Composition and teaching: queen-and-king mates, queen endgames, and problems such as the eight queens puzzle
- Which of these real-world use hold for the sense of queen this model covers, and on what evidence? provenance
Typical measurements
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Conventional material value - about 9 (slightly more than rook+bishop, slightly less than two rooks) - pawn units
- Starting complement - 1 per side (more than one possible after promotion) - pieces
- Maximum squares attacked on an empty board - up to 27 from a central square (e.g. d4 or e4) - squares

Failure modes and hazards
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Hanging or trapped queen: the piece is captured because it is undefended or has no safe square
- Illegal slide: attempting to pass through an intervening piece (queen cannot jump)
- Confusion with the king in cheap or poorly differentiated sets (both wear a crown-like top)
- No spare queen available on promotion; FIDE practice allows an inverted rook as a substitute
- Physical damage or tip-over of a top-heavy coronet, or pieces that cannot be told apart at a glance
- Which of these failure modes and hazards hold for the sense of queen this model covers, and on what evidence? provenance
Regional variation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- English queen versus Romance dame/dama/donna/reine and German Dame; Russian professional usage keeps ферзь (ferz), not королева
- Algebraic initials differ: Q (English), D (German, French, Spanish), Ф (Russian), and other local letters under FIDE Appendix C
- Arabic and several Asian languages retain vizier/minister names; Polish uses hetman; Estonian uses lipp (flag); historical Russian play sometimes allowed a queen that also moved as a knight (the fairy amazon)
- Which of these regional variation hold for the sense of queen this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- king (chess) - The king is the tallest piece, often topped with a cross, moves only one square, and cannot be captured; capturing the queen does not end the game
- rook (chess) - A rook moves only along ranks and files, never diagonally, and is typically battlemented rather than crowned
- bishop (chess) - A bishop moves only diagonally and is colour-bound; the queen is not colour-bound and also slides orthogonally
- ferz (historical counsellor) - The ferz, the queen's predecessor, moves only one square diagonally
- amazon (fairy chess) - An amazon combines queen slides with a knight leap; the standard queen cannot jump
- queen (playing card) - A rank in a 52-card deck, identified by suit and face, not by chess movement or board square
- queen (monarch or insect caste) - A person or a reproductive animal, not a game piece; those senses sit in other registry domains (SOC.PER, PHY.LIV)
- Which of these neighbouring kinds and how to tell them apart hold for the sense of queen this model covers, and on what evidence? provenance

What the second pass must settle
- Does vr.tr.queen mean a physical chess queen, a human queen, an insect queen or another sense? PHY / PHY.OBJ alone does not resolve the missing definition.
- If the chess interpretation is confirmed, does an existing Vercy model already own this concept or its game-role component?
- Which chess rules and variants must be supported, and which authoritative sources establish their queen movement and promotion requirements?
- What evidence establishes queen and side identity for the actual sets covered, especially abstract designs and substitute pieces?
- Where should Vercy place the boundary between the enduring physical object and the queen role created or continued through promotion and replacement?
