What is stalemate?
There is a stalemate when the player whose turn it is to move • is not in check • has no legal move Consider for example the following position: Suppose it is the turn of black to move. Black has no legal move: his pawn cannot move, and his king also cannot move as every place it could go is attacked by white. The knight also cannot move, as moving the knight would mean that the white rook would give check. Also, white does not give check to black, so it is a stalemate. In case of a stalemate, the game is a draw: 1/2 – 1/2.
