How many checks does it take before the person in check can claim perpetual check?

I think it's after 3 moves. You can just claim a draw...

Seriously? Only 3?

If the position isn't repeated 3 times and your opponent keeps checking you but doesn't want to agree to a draw then about 50

Well, I know about 3-fold repitition and the 50 move rule, but I thought that after a certain number (not 3 or 50) of consecutive checks, then the game would also be a draw...

Once your in perpetual check, you gotta be an idiot not to draw.

Sorry, I mean repeating the position 3 times. I don't think there is an actual rule on perpectual check but a mediator should be able to review the position and determine the draw.

Wikipedia says that perpectual check has removed from the rules of chess because a draw will usually result from the threefold repetition or fifty move rule.

No perpetual check is a draw precisely because it forces one of those two rules.

Perpetual Check is a draw only because its a certain instance of either of these scenarios. I'm pretty sure its not a real rule, but rather just a phenomenon.

Does anyone know what year it was removed from the official rules?

seeing as it is redundant, does it matter?

It does to me.

I seem to remember that as something I understood to be a rule, if so it would have been the result of reading my 1977 official rules of chess.

I more recently was looking through the rules and found there was not actual perpetual check rule (other than the obvious ability to generate a 3x repetition or 50 move rule from a perpetual check). Now I am curious as to whether I misread the rule book several years ago, or if the rule changed since I first read the rule book.

There was never a specific rule on perpetual check.

Perpetual check is simply one particular means of forcing either a 3-fold repitition or the 50-move rule.

It would be interesting to see if it would be possible to even invoke the 50-move rule using perpetual check... you would think that there would be a repeat of the position at leat 3 times after 50 moves.


I guess maybe if there is only a K+Q vs K and the person doesn't know how to mate it could be possible.

Honorable men should not nit-pick, but since I'm not honorable, here goes.

Since the 3x repeat needs to be claimed by a side in order to take effect, one could always forgo the claim for a 3x repeat and strive for the 50 move rule. If your opponent were equally childish, it could happen.
