Frequently Asked Questions

Using any external assistance during a live, rated game on Chess.com or Lichess is, in the strictest and most 'please don't involve me in the aftermath' sense, cheating — their fair-play systems are very good at quietly removing accounts that try it. But studying your blunders, reviewing positions, or figuring out why your rook behaved like it had personal errands is completely legitimate and something everyone does, even the people who swear they don't. Chess Cheater is technically built for that legitimate, educational use: every suggested move includes the tactic behind it, so you're not just pressing buttons but absorbing patterns like a responsible, law-abiding student of the game.

Yes! This is a totally free tool. We certainly like money and could've cooked up some elaborate business plan to shake a couple quarters out of your piggy bank, but tearing down barriers and making chess more fun for everyone is the whole point. If you get a lot of value out of it, consider exploring our sponsors or grabbing something from our Gift Recommendations — it helps keep the lights on and the blunders educational.

FEN (Forsyth–Edwards Notation) is a single line of text that describes a chess position so precisely it might as well be a GPS coordinate for your pieces. It tells you where every piece is, whose turn it is, castling rights, the en passant square — basically everything except how you got into this mess. For example, the starting position is rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1, which looks like someone fell asleep on their keyboard but is actually perfectly valid. Paste any FEN into the calculator and it'll analyze that exact position, no judgment about how chaotic it became.

Use the free image-to-FEN converter: upload a screenshot of the board from Chess.com, Lichess, or a photo of a physical board, and it detects the pieces and produces the FEN automatically. From there you can send that position straight to the move calculator to get ranked move suggestions.

Well… sort of. They don't exactly send us holiday cards, but a screenshot of any position from Chess.com or Lichess usually parses just fine. You can paste their FEN directly, or upload a board screenshot and let the converter extract the FEN for you like a little digital archaeologist. The calculator is blissfully platform-independent — it analyzes the position itself, not the website — which is a polite way of saying it works everywhere, even in places that would prefer we didn't exist.

Accurate enough that you'll wonder why you didn't see the move yourself, but not so omniscient that it starts predicting your life choices. It weighs all the usual chessy things, spots tactics, and points you in the right direction without bragging about it. Think of it as "strong, sensible guidance" rather than "the voice of destiny."

Yes. Recommended moves are labeled with the tactic they leverage — forks, pins, skewers, discovered checks, and back-rank threats — and the calculator also warns you about threats against your own position. If you want to study these patterns in depth, the tactics guide walks through how to spot and defend against each one.

Nope. Chess Cheater runs entirely in your browser like a polite houseguest who doesn't touch anything. There's no sign-up, no download, no extension, no 'just one quick permission,' nothing — you open the page, paste a FEN or upload a screenshot, and boom, instant analysis. It's the rare tool on the internet that doesn't demand your email, your data, or your firstborn.
