++ sign

Sort:
RetiFan

When using algebraic notation, I knew that + means check and # means checkmate. When I first saw ++ sign, I intuitively thought that this should mean double check, because of the double plus. However, if you look here: "http://www.fide.com/component/handbook/?id=125&view=article". Appendix C.13 says that ++ also means checkmate, isn't this a bit confusing? Shouldn't it be meaning double check insted of checkmate(#)??
