Stalemate
Stalemate and checkmate look identical: a player with no legal move. One wins the game and the other throws it away, and the difference is one word - so the only useful way to learn it is to be shown positions and made to call them.

Stalemate is a position where the player to move has no legal move and is not in check. The game ends there, immediately, as a draw.
Checkmate is a position where the player to move has no legal move and is in check. That player loses.
That is the entire difference. One word, and it decides whether you have won or thrown away a whole game - which is why reading the definition never sticks and being made to call positions does.
Six positions below. Say which each one is before you press anything.
Black to move. Which is it?
The one test that always works
When you think you have mated, ask the two questions in this order:
- Is the king attacked? If not, and they have no move, it is stalemate - a draw.
- Does the opponent have any legal move at all? If they do, it is only check, and the game goes on.
Both answers have to line up for a mate. In a real game the mistake is almost never mistaking check for mate; it is the first question, asked too late.
Why the rule is worth caring about
Because it turns a lost game into half a point. A player who is a queen down does not need to find a way to win - they need to find a way to have no legal moves. Give away everything that can move, get the king cornered, and the opponent's own crushing material advantage becomes the problem: every square is covered, and covering every square is exactly what stalemate needs.
The practical consequence when you are the one winning: count your opponent's moves before yours. The king and queen ending is the one to watch, because a natural queen move can take away four squares at once.
Not the same as a draw by agreement
Stalemate is one of several ways a game can be drawn, and it happens automatically the moment the position appears - no claim, no agreement, no counting. A dead position works the same way: the instant neither side could possibly deliver mate, the game is simply over. The other draws need something extra: a threefold repetition or the fifty-move rule has to be claimed, and a draw by agreement needs an opponent who says yes.
Try it
Black to move. Call it.
Common questions
- What is stalemate in chess?
- A position where the player to move has no legal move at all and is not in check. The game ends immediately as a draw - nobody wins. It is the one situation in chess where being unable to move is not a loss, and it exists because the rules never let a player make an illegal move to save themselves.
- What is the difference between stalemate and checkmate?
- One word: check. Both are positions where the player to move has no legal move. If their king is under attack it is checkmate and they lose. If their king is not under attack it is stalemate and the game is drawn. Nothing else distinguishes them, which is why they are so easily confused.
- Is stalemate a draw or a win?
- A draw. Each player normally scores half a point. This matters enormously in practice: a player who is hopelessly lost can save the game by engineering a stalemate, so being a queen up is not the same as having won.
- Can you stalemate on purpose?
- Yes, and it is a real defensive technique rather than a curiosity. A losing player looks for ways to strip their own position down until their only piece is a trapped king, often by giving pieces away deliberately so that there is nothing left that can legally move. Endgame books are full of these saves.
- Why is stalemate not a win for the attacker?
- Because the aim of chess is to attack the king, not to run the opponent out of moves - and in a stalemate the king is not being attacked at all. There is a long historical argument here: some earlier versions of chess did score it as a win, and the modern draw rule only settled in the 19th century.
- How do I avoid stalemating my opponent?
- In a winning endgame, count your opponent's legal moves before you move, not after. The classic accident is a king and queen against a lone king, where a natural-looking queen move takes away every square at once. Keep a spare pawn move in hand, or give the enemy king a square to breathe while you bring your own king up.
