From: John Kenney EMBL-HEIDELBERG DE> Date: 4 feb 1993 Subject: Re: Castling Just one clarification: the players may have official grades, but as far as the ladder is concerned I think they are "unofficial" in the sense that ladder results are not used to grade anyone and that because the playing is different than in face to face tournament games the official grades are not as meaningful for ladder play (as pointed out already). Of course the grades are useful guidelines for judging potential opponents. I guess the only official thing is the ladder standing! John (Kenney EMBL-Heidelberg DE)
