Draws & stalemate
Not every game has a winner — here are the ways a game can end in a draw.
Stalemate
If it's your turn but you have no legal move — and your king is NOT in check — the game is a draw. This is called stalemate. It's the most common surprise draw for beginners.
White's king isn't in check, but every square around it is controlled by the black queen. No legal move = stalemate = draw.
Stalemate vs checkmate
Checkmate: the king IS in check and can't escape.
Here the queen is on b7 instead — now the king IS in check, and there's no escape — The king cannot capture the queen as the Rook guards it. That's checkmate, not stalemate.
Insufficient material
If neither player has enough pieces left to checkmate, the game is automatically a draw. For example: king vs king, king and bishop vs king, or king and knight vs king.
A lone bishop can never deliver checkmate, no matter how well you play. So this is an automatic draw.
Threefold repetition
If the same position appears three times with the same player to move, either side can claim a draw.
The 50-move rule
50 moves with no pawn move and no capture — either player can claim a draw.
Draw by agreement
Both players can agree to a draw at any time. One offers, the other accepts.
