The fifty-move rule lets either player claim a draw if the last 50 moves by each side (100 moves total) have passed with no pawn move and no capture. In other words: if the game has gone 50 full moves without anything irreversible happening, it can be declared drawn.
The logic is simple. Captures and pawn moves are the only things in chess that can’t be undone — a captured piece never comes back, and a pawn never moves backward. If neither has happened in a long time, the players are just shuffling, and the rule stops a hopeless position from dragging on forever.
How to count it
The counter resets to zero every time a pawn moves or a piece is captured. Any 50 moves each without one of those events, and the draw is available on request. Online platforms track this for you (you’ll often see the game just end); over the board, you keep score and claim it.
When it actually comes up
Most games end long before 50 quiet moves pile up. The rule mainly matters in endgames where one side can’t force a win — like the two-knights-versus-king position above, or certain fortress positions — where the stronger side keeps trying but simply can’t make progress. It also caps drawn-out technical endings (some are winnable, but only within the 50-move window).

Frequently asked questions
Is it 50 moves or 100 moves? It’s 50 moves by each player — so 100 half-moves (plies) in total — with no capture and no pawn move.
Does the count reset? Yes. Any capture or any pawn move resets the counter to zero, and the 50-move clock starts over.
Is the draw automatic? Normally a player must claim it. There’s also a stricter seventy-five-move rule that ends the game automatically even if nobody claims.
