perpetual check on chess.com

The software does not seem to recognize perpetual check. I am in a game where my opponent has not agreed to a draw despite perpetual check, so in reality it may actualy turn out to be perpetual check.

I am concerned that this game may go on for the next 20 years.

Have you tried clicking the "Claim Draw" button?

Actually, there is no such thing as perpetual check.

You can claim a draw when:

• the same position has occured 3 times
• 50 moves have been made without a pawn move or a capture

And, on this site, it works.

there is no such thing as perpetual check

Yes there is, and it is a draw

Have you read this?

This part in particular:

In online or turn-based chess, once the position is repeated three times, make your move.  Now, on the screen for that game, just below the notations box there will be text for you to click on that says 'claim game'. Click on that to claim the draw.  This method also works for the 50-move rule, which states that the game may be drawn if 50 moves (2 ply) are played with no captures and no pawn moves.

No, there's not

It's not a rule, just a concept. The information rooperi provided is correct, if a bit short.

Actually, there is such a thing as perpetual check, but that doesn't make it a draw. It is drawn by what others have already stated.

You have to claim the draw just like in OTB chess. the server doesn't automatically draw the game for you.

you can draw the game by clicking the "draw" button as others have suggested :)

yeah but he said 'there is no such thing as perpetual check'

Perpetual check is a condition upon which players typically agree to a draw in anticipation of either threefold repetition or the 50 move rule being invoked.

There is no rule that directly addresses perpetual check.  This is because the threefold repetition and 50 move rules are sufficient to address the situation.

Perpetual check is not a rule, but a concept, just as ivandh said.

But only after the conditions under which a draw can be claimed have been met -- i.e. threefold repetition or 50 moves without a capture or pawn move.

We posted at the same time TheGrobe. :)

@ thegrobe,

Right, thanks :)

Yep.  Perpetual check is not a rule - it's a method allowing a player to force threefold repetition to secure a draw.

I think you mean "claim draw".

There seems to be quite a bit of confusion, so here is an article about lemurs.
