Check, Checkmate, and Stalemate: How a Chess Game Ends
Learn the difference between check, checkmate, and stalemate in chess, and understand exactly when a game ends and why.
Chess games end in one of three ways: one player resigns, both players agree to a draw, or the position on the board forces a conclusion. That forced conclusion is almost always checkmate (a win) or stalemate (a draw). Understanding the difference between these two outcomes is one of the most important things you can learn as a beginner.
Here is the short version before we go deeper:
- Check means the king is under attack right now. The side in check must deal with it immediately.
- Checkmate means the king is under attack and there is no legal way to escape. The game ends. The player who delivered checkmate wins.
- Stalemate means the side to move has no legal moves at all, but the king is NOT currently under attack. The game ends as a draw.
The distinction between checkmate and stalemate catches a lot of beginners off guard. In checkmate the king is attacked. In stalemate it is not. That one detail changes the result from a win to a draw.
What Is Check?
Your king is in check when an enemy piece is attacking it. The rules require you to get out of check on your very next move. You cannot make any other move, and you cannot leave your king in check voluntarily.
There are three legal ways to escape check:
- Move the king to a square not attacked by any enemy piece.
- Block the attack by placing one of your own pieces between the attacking piece and the king.
- Capture the attacking piece with the king or with another piece.
If none of those three options is possible, the position is checkmate.
A few things check cannot do: you cannot castle out of check, and you cannot block a knight's attack (knights jump, so interposing does not work). You can only move the king or capture the knight.
What Is Checkmate?
Checkmate is when the king is in check and every possible escape is cut off. The attacked player has no legal move that removes the threat. The game is immediately over, and the player who delivered checkmate wins.
You will see it written as # in game scores. The notation Qh7# means a queen moved to h7 and that move was checkmate.
A simple example is the Scholar's Mate, one of the earliest traps beginners encounter:
1. e4 e5
2. Bc4 Nc6
3. Qh5 Nf6??
4. Qxf7#
After 4. Qxf7, Black's king is attacked by the queen on f7. The king cannot move to e7 (still attacked), cannot capture the queen (the bishop on c4 covers f7), and no piece can block. That is checkmate. The game ends on move four.
To give checkmate you do not need to say anything aloud. The board position tells the story. If your opponent's king is in check and has no escape, the game is over.
What Is Stalemate?
Stalemate occurs when the player whose turn it is has no legal move and their king is NOT in check. The result is a draw, not a win for either side.
This trips up beginners in two ways. First, a player who is clearly winning can accidentally stalemate their opponent and throw away the win. Second, a player who is clearly losing can sometimes force stalemate as a defensive trick.
A classic stalemate trap looks like this:
White: King on g6, Queen on f7
Black: King on h8
White to move plays Qg7??
After Qg7, Black's king is not in check but has no legal square to move to. h7 is covered by the queen, g8 is covered by the queen, and g7 is occupied. Stalemate. What should have been a simple win for White turns into a draw.
The correct approach is Qf8# or Kf6 first to give Black a safe square, then escort the king to the corner with checkmate.
Stalemate most often appears in endgames when one side has very few pieces left. A lone king in a corner with no moves is a common stalemate setup. If you are the side ahead on material, always check that the position you are leaving your opponent still has at least one legal move before you celebrate.
Checkmate vs. Stalemate: A Quick Comparison
| Situation | King in check? | Legal moves? | Result |
|---|---|---|---|
| Check | Yes | Yes, at least one | Game continues |
| Checkmate | Yes | No | Win for the attacker |
| Stalemate | No | No | Draw |
The rule that connects all three: a player can never be forced to leave their king in check. If there is no way to clear the check, it is checkmate. If there are no moves at all but no check either, it is stalemate.
How to Avoid Stalemate When You Are Winning
New players frequently stalemate opponents who are down to a lone king. Here are the patterns that cause it:
- Placing your queen where it covers every square around the enemy king while the king has no check to justify the position.
- Pushing your opponent's king into a corner too quickly without leaving an escape square for the final move.
- Queening a pawn immediately when that queen would cover all remaining squares.
The fix is to think one step ahead. Before you make a move, ask whether your opponent will have any legal reply. If the answer is no and you are not giving check, stop and find a different move.
When you are the player with the lone king, stalemate is a lifeline. Keep your king active and try to get it to a corner or edge where your opponent has fewer maneuvering options. If your opponent plays carelessly, you may earn a half-point from a losing position.
Other Ways a Chess Game Can End
Checkmate and stalemate are the two outcomes forced by the board position, but games end in other ways too:
- Resignation: A player who sees they cannot avoid checkmate will often resign rather than play on. This is standard practice and considered good sportsmanship.
- Draw by agreement: Both players agree the position is equal or neither wants to play on.
- Threefold repetition: The same position appears on the board three times with the same player to move. Either player can claim a draw.
- The 50-move rule: If fifty moves pass without a capture or a pawn move, either player can claim a draw.
- Insufficient material: If neither side has enough pieces to deliver checkmate (for example, king vs. king, or king and bishop vs. king), the game is declared a draw.

Frequently Asked Questions
Is stalemate a win for the player who caused it?
No. Stalemate is always a draw, regardless of how much material the stalemating side has. Even a queen and seven extra pawns cannot turn a stalemate into a win. This is why avoiding stalemate when you are ahead is so important.
Can you be in check from two pieces at once?
Yes. This is called double check, and it can only be escaped by moving the king. You cannot block both attacking lines at once, and you cannot capture both pieces in one move. Double check is one of the most powerful forcing moves in chess.
Do you have to say "check" when you attack the king?
In casual games many players announce check as a courtesy, but it is not required by the rules. In tournament play, you are responsible for noticing that your king is under attack. Relying on your opponent to warn you is not a rule.
What happens if I accidentally move into check?
The move is illegal and must be taken back. You then have to make a legal move with the same piece if possible. In tournament play under touch-move rules, you must move the piece you touched to any legal square. If there is no legal square for that piece, you can move it back and choose a different piece.
Can a king give checkmate?
Yes. A king can participate in delivering checkmate by controlling squares that cut off escape, though the king itself cannot move into a square attacked by the enemy king. In endgames, the king is an active piece and often essential to delivering mate. The opposition technique, where kings face each other with one square between them, is a foundational endgame concept covered in how the chess pieces move: a beginner's guide to all six.
Check, checkmate, and stalemate are three distinct situations that beginners sometimes blur together. The clearest way to keep them straight: check is a warning, checkmate is the end of the game as a loss, and stalemate is the end of the game as a draw. Once those distinctions click, you will start to see potential mates and stalemate traps several moves in advance, which is where chess begins to get genuinely interesting.
