A draw can be claimed without any interaction from your opponent under a number of conditions. These are as follows:
* No piece capture or pawn movement has occurred for over 50 consecutive moves (100 half moves). Therefore the game has not progressed and a draw may be claimed by either player during their next move.
* Insufficient material remains on the board to finish the game. If only two kings remain then either player may claim a draw during their next move.
* Third repetition of a position. If any identical position appears three times during a game, then the game can be claimed as a draw. Please note that each repetition must be identical with regards to en passant and castling availability. A draw can only be claimed along with a move that contributes to a repetition. Claiming after the repetition has occurred is not possible, unless the same position can be repeated again on a future move.
