White's manifesto for a win against 58...Qf5
Arranged into tree form from the copy on 99% Energy's bulletin board, no
moves added. Very lightly edited by KWR, mostly navigational aids such as
the remark on the first line. All KWR edits except grammar fixes are in
[...] or --------in dashes----------. Position G is here.

[Main point is that with Black's King on b1, Black manages to get his
counterplay jump-started in time against the Kf8 idea---but after
we induce the King to move to a2, Black won't have enough time. KWR]
