What it is
This template checks every move with its own mate solver and ships puzzles found by that solver.
How you use it
Unzip, serve the folder and open index.html, then edit game.js; npm test plays it again in headless Chrome.
Source code of a real, playable game to reskin and learn from, with a smoke test whose bot plays it.
Use it when
Built for
After a move, the solver asks whether Black can still avoid mate within the moves left; if not, the move counts, whatever it is. Black then picks the reply whose mate is furthest away.
Positions with a cornered king and a few attackers were generated and searched; only those with mate in exactly N and a single key move for N of two or three were kept.
Plain JavaScript and Canvas 2D; open index.html through any static server and edit game.js.
A headless Chrome test loads the game, checks the console, presses keys and taps, and lets the built-in bot play a run to its result screen.
