Building a "Mate-in-One" Chess Puzzle Solver from Scratch

Short summary

Learn to build a mate-in-one chess detector by parsing FEN notation into an 8x8 board state, generating legal moves, and verifying the opponent has no escape routes. The tutorial provides JavaScript code for each step, from candidate move generation through checkmate validation. A practical algorithmic exercise useful for game development and problem-solving.

• •Three-step algorithm: candidate moves → check detection → escape elimination
• •FEN notation parses board state into 8x8 array representation
• •JavaScript code examples demonstrable for immediate implementation
