Three Move Draw[Subject Thread] [Add Response]

Ed wrote on Sun, Sep 29, 2002 06:12 AM UTC:

Hi,

Can someone state the rule regarding when the King is checked three
consecutive times and it moves to the same two squares back and forth? 
Does this result in a draw?  

Suppose the King had other squares that he could have moved to but chose
the same ones to force a draw. Is this valid? Would this be a draw?

Does it matter which of the opponent's pieces were involved in giving
check? 

If I am not being very clear in my question, I do apologize, but therein
lies the problem: I do not clearly understand this rule; though, I do know
that such a rule exists.  Would someone clarify?

Appreciatively,

Here's the rule from our FIDE laws page
(http://www.chessvariants.com/fidelaws.html):

10.10
The game is drawn, upon a claim by the player having the move, when the
same position, for the third time: 
(a) is about to appear, if he first writes the move on his scoresheet and
declares to the arbiter his intention of making this move; or 
(b) has just appeared, the same player having the move each time. 
The position is considered the same if pieces of the same kind and colour
occupy the same squares, and if all the possible moves of all the pieces
are the same, including the rights to castle [at some future time] or to
capture a pawn 'en passant'.

Hi David,  thank you for your reponse.  Then, this rule (10.10) may not
involve any check's.  I really thought it revolved around checking the
King.  I guess not...    ...thanks again.

Legally, triple repetition does not require any checks. However, by far the
most common triple-repetiton draws are those involving perpetual check. I
have never experienced any other type in any game I've played or
observed.

In older verisons of the FIDE laws, perpetual check was a drawing
condition in its own right--then someone observed that pepetual check
would alway eventually lead to triple repetition, allowing the laws to be
simplified.
