wondered that aswell, but the rules are the rules.
Rules Contradiction...

I Just looked in the archives of my chess attic. and King luis The VII set in Motion and enforced a rule That stands today.... rule #4177....... "You May Move Your King Into Puting Himself in check, But, you Must Lay Your king Over on his side when You Do...(which means Resignation) .
Have you ever wondered.......
Moving your king into check is against the rules. If the piece checking you, however, would have to uncover check to "take" your king, then, on some level, you are not really in check at all. Whaddya think? Can I argue my case before the supreme court of chess?
