With only a king left, how many moves remaining until a draw? I am a beginner in chess. If I have only a king left, how many moves does my opponent have to mate me?
Your opponent has 50 moves, but every time a pawn is moved the count is reset.  So, he could have hundreds of moves if he has a few pawns on the board.  If he has no pawns, then 50.

The count is also reset if any piece or pawn is captured.
