I don't know if Goldfish 0.2 is different from Tideman's original
wording, which I've just received, and haven't completely
figured out yet.
When you eliminate the loser of a pairwise comparison, then,
as far as that candidate is concerned, that's a lot like locking
in his defeat.
But the copying of his victories from his row into the row
of the candidate who beats him seems different from Tideman,
and original. The consequences aren't obvious to me without
trying it out in examples.
