In chess, the threefold repetition rule states that a player may claim a draw if the same position occurs three times. ... The game is not automatically drawn if a position occurs for the third time – one of the players, on their turn, must claim the draw with the arbiter.
I think a threefold repetition is one of the situations here where you will need to claim the draw when you submit your move. If you have the correct conditions but do not claim the draw, it will not be automatically awarded. If you think you have the draw, just go ahead and claim it. If you are wrong, your claim is ignored and the game continues normally. The "claim draw" button is only present when it is your turn to move.
@dickkopfsaid @Ponderable The chess partner didn't make a move, so I took the time out. It's a shame, I really wanted to test the system.
I can help you to test it.
I will send you a an unrated game.
We will take turns moving just one knight back and forth to the same two squares. On each of your moves, click 'claim draw' then submit your move.
The first two repetitions nothing should happen, but on the third repetion of positons the game should become drawn.
I will now send a game.
@DickKopf No problem.
With the 'offer draw', that can be sent at any time with a move, and it is just a mutually agreed draw if both players want it.
When you 'claim draw', that does not require any action from your opponent, it is granted only when the conditions are correct. As far as I know, that means '3 time repetition of the same position', 'insufficient material to mate', or the '50 move rule'.
