About Checkmate Clarified

Chess has plenty of rules that seem simple until a specific situation comes up.

Can you castle if your rook is under attack? What happens when a player has no legal moves? Is a move still legal if you touched a piece by mistake?

Checkmate Clarified exists to answer those questions clearly.

We’re a small team of chess players who kept noticing the same thing: most chess content online either teaches total beginners the basics, or assumes you already know the rules inside out. There’s not much for the moment in between, when you already know how to play, but a specific situation at the board leaves you second-guessing.

We focus on exactly those situations, the rules that are easy to misunderstand or argue about mid-game.

Every article is researched directly against the FIDE Laws of Chess, chess’s official rulebook, and cross-checked where relevant against established tournament-arbiter guidance. We explain each rule in plain language and use concrete board examples where they make a situation easier to picture.

We don’t aim to replace the official rulebook. Our goal is simply to make its trickier corners easier for everyday players to understand.

If you’ve ever stopped mid-game and thought, “Wait, is that actually allowed?”, you’re in the right place.
