Everything is OK with what I said, Snaike. By "toppling him", I simply mean that Claremoreblue only needs to play a single Ladder game in which he (maybe!) defeats HBThree, thereby causing HBThree to lose his no. 1 spot. That's all I meant (topple, not replace HBThree or whoever the current Ladder leader might be).
(Of course it would be quite a different, and far more difficult, thing for Claremoreblue himself to advance to the no. 1, and I already said so in this forum, also in another thread.)
You know, the beauty of the Ladders is that any of the big guns – Tibbets, AvatarLee, Nivlac, Thunderbird et al – can just play a single Ladder game, but can dethrone the current Ladder 9 or Ladder 18 leader in that single game. If the current Ladder leader is brave enough, of course, to accept a challenge from the very best players on this site, and I'm sure he/she would be, no matter who the current Ladder leader might be. (And if such a game ever came to pass, I certainly would wish for WGT to enable the Spectator Mode!)
