Tampermonkey Chess Script Exclusive Guide

Unlike free, outdated scripts found on GreasyFork, this version includes:

Unlock the full potential of your online chess experience with this premium, proprietary Tampermonkey script. Designed for serious players, content creators, and puzzle solvers, this script goes far beyond basic move highlighting.

Before you even touch a piece, an exclusive script can color-code every legal square. It might show: tampermonkey chess script exclusive

The script waits for the chess board’s canvas or SVG elements to render. It attaches listeners to mousemove, click, and dragend events. Instead of directly modifying the board, it reads the FEN (Forsyth–Edwards Notation) from the game state.

Instead of hunting for risky “exclusive” scripts, consider writing your own utility script for learning. Here’s a simple, ethical template that works on Lichess: Unlike free, outdated scripts found on GreasyFork, this

// ==UserScript==
// @name         Chess Opening Reminder
// @namespace    http://tampermonkey.net/
// @match        https://lichess.org/*
// @grant        none
// ==/UserScript==
(function() 
let lastFEN = '';
setInterval(() => 
const fenBox = document.querySelector('.fen');
if (fenBox && fenBox.value !== lastFEN) 
lastFEN = fenBox.value;
// echo the FEN to console — ethical, no engine eval
console.log('Current position:', lastFEN);
, 1000);
)();

This script only prints the game position to your browser console. It doesn’t evaluate, recommend, or automate. Combine that with a local chess database, and you have a powerful study tool that violates no rules.
