Talk:Perpetual check
From Wikipedia, the free encyclopedia
I must have lost a point somehere, but isn't the knight on g5 ? How can it jump to g4 ? Is there aomething wrong somewhere ? (if what's wrong is in my head, I'd be glad to know what... ^^;; )
[edit] historical perpetual-check rule
I have been Googling for a while and haven't found anything saying that "perpetual check used to be in the laws of chess". The best I could find was a mention by Staunton that it is a special case of the threefold repetition rule (which is the same status perpetual check has now - a tactic, not an independent drawing method). However, I haven't found a citable source saying there was never such a rule (just a lot of forum posts). I don't discount that whoever said there used to be a perpetual-check rule might have had some basis for saying that, so I am asking for a source citation.JoeJust 21:49, 22 March 2007 (UTC)
- Official Chess Rulebook by Kenneth Harkness, 1970, page 46, says
...commonly known as the draw "by repetition of moves." It includes perpetual check
