Insufficient Material.

(assuming no pawns) against a lone King:

 

1) lone King,

2) King and one Knight,

3) King and one Bishop. A player must claim the draw, otherwise play continues (either player may still lose on time).

 

Draw by Repetition.

If the same position occurs 3 times (not necessarily on consecutive moves) with the same player to move, either player may point this out and claim a draw. If neither player claims the draw, play continues (either player may still lose on time).

 

Stalemate.

If a player has no legal moves on his/her turn, but is not in check, the game is over and the result is a draw.

 

Fifty-Move Rule.

If either player makes 50 consecutive moves without moving a pawn or making a capture (irreversible moves), either player may claim a draw. If neither player claims the draw, play continues (either player may still lose on time).

 

Draw by Agreement.

Players may offer a draw at any time during a game, but preferably immediately after making a move. If the opponent wants to accept the draw offer, he/she must do so before making a move, otherwise the draw offer expires. Draw offers may be repeated.
