Provides a structured methodology for encoding intricate chess rules—including piece movement, captures, and legality checking—entirely within the constraints of regular expression patterns. This skill treats game logic as a 'compile-to-constraints' problem, guiding users through multi-stage transformation pipelines that expand FEN notation, manage coordinate ordering, and detect sliding piece obstructions. It offers practical frameworks for building pattern-based game engines and helps developers translate sophisticated business logic into limited formalisms through systematic decomposition and incremental verification.
