Description
Chess opening references depend on move order, notation, transpositions and the chosen classification edition.
Chess opening references depend on move order, notation, transpositions and the chosen classification edition.1
This tool retrieves an exact caller-supplied opening record rather than recognizing a position or loading an opening database.
When to use Chess Opening Name Lookup
Use this tool to select a specific record from a reference set you have independently verified.
How to use Chess Opening Name Lookup and how it works
- Identify the applicable source edition, conditions and date for Chess Opening Name Lookup.
- Enter that context and the aligned reference keys and texts, then set queryReferenceKey to an exact key.
- Run the tool and read result.qualifiedReferenceText together with result.source, result.context and result.asOfDate.
- If the key is rejected, inspect spelling, case, duplicate keys and list alignment; review the selected record against the original source before applying it.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerVerifiedSource | Identifier for the source and edition independently checked by the caller. | string | required; further conditions in the algorithm |
| callerVerifiedContext | Applicability, units, population or measurement conditions for the supplied evidence. | string | required; further conditions in the algorithm |
| callerVerifiedAsOfDate | Real Gregorian as-of date in YYYY-MM-DD format. | string | required; further conditions in the algorithm |
| callerReferenceKeys | Distinct nonblank exact identifiers aligned with reference texts. | array of string | required; dense; align related rows as specified; at most 128 strings; 128 UTF-16 units each; further conditions in the algorithm |
| callerReferenceTexts | Nonblank records aligned with reference keys; supplied by the caller. | array of string | required; dense; align related rows as specified; at most 128 strings; 512 UTF-16 units each; further conditions in the algorithm |
| queryReferenceKey | Exact case-sensitive key of the record to retrieve. | string | required; further conditions in the algorithm |
Validate a nonblank bounded source and context and a real Gregorian as-of date. Require aligned nonempty keys and texts, distinct nonblank keys and nonblank records. Find the query with exact case-sensitive index matching; return that record and source, context and date unchanged. An absent key is an input error. No source is fetched or independently verified.
selected text = callerReferenceTexts[indexOf(queryReferenceKey in callerReferenceKeys)] Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.qualifiedReferenceText | Exact selected caller-supplied record text, unchanged. | string |
| result.source | Caller-supplied source identifier, returned unchanged. | string |
| result.context | Caller-supplied applicability context, returned unchanged. | string |
| result.asOfDate | Caller-supplied Gregorian as-of date, returned unchanged. | string |

}Limitations and assumptions
The operation is caller-reference retrieval. You supply and verify the relevant records; the title does not imply an installed authoritative table, scientific classifier, calculator or assessment. Source accuracy, rights, applicability and freshness are external responsibilities.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A returned boolean, signed difference or tied result follows the stated convention; an input error instead means the required input contract was not satisfied. Very large inputs or outputs may be rejected by shared resource limits.
