Bridge Hand Editor

This Bridge Hand Editor provides a precise, standards-compliant workspace to build and edit card deals for analysis and teaching. It accepts inputs for four suits, validates total card counts, and computes high-card-point totals and distribution patterns. It supports manual entry, import from common bridge notation, and export to PBN or Bridge notation. Target users include club players, instructors, and students who require repeatable, machine-readable hand definitions and easy sharing for asynchronous study. The tool emphasizes data accuracy, reproducibility, and interoperability with other bridge tools without performing live gameplay.

Conceptually, the editor treats a deal as four suit lists that jointly contain 13 cards for a single hand. Each suit input is constrained to 0–13 cards, and the tool checks for duplicates across suits. Core features include a per-hand validation engine, computed HCP, suit distribution vector, and export/import options. Advanced uses include saving multiple hands for comparison, generating random deals for practice, and exporting to widely used formats for teaching materials or match prep.

Unique differentiators include strict validation ensuring 13 cards per hand, native support for standard bridge notations, and seamless interoperability with external datasets. The tool is designed for learners and coaches who require repeatable, machine-readable hand definitions and easy sharing for asynchronous study. Use cases include classroom demonstrations, self-paced practice, and record-keeping for post-game analysis. The editor remains UI-agnostic in this description but provides a robust, backend-ready data model for constructing and validating bridge deals.
