This is what I needed.  Thank you.

Draws

Occasionally chess games do not end with a winner, but with a draw. There are 5 reasons why a chess game may end in a draw:

1. The position reaches a stalemate where it is one player’s turn to move, but his king is NOT in check and yet he does not have another legal move
2. The players may simply agree to a draw and stop playing
3. There are not enough pieces on the board to force a checkmate (example: a king and a bishop vs. a king)
4. A player declares a draw if the same exact position is repeated three times (though not necessarily three times in a row)
5. Fifty consecutive moves have been played where neither player has moved a pawn or captured a piece.
