[Retros] StrateGems 49 (Jan-Mar 2010)

[Kevin Begley]

In retrospect (which would be a nice name for a problem journal!), I
think "variants" is the wrong word too, since it has a specific
meaning in ProofGames, which is completely different from my intended
usage here.

I might better have said "3 retro-variants."
I believe there is 1 solution, with 3 (unique) retro-variants... not 3
sols, not 3 vars.
I must have been trying to hint at this, but I should have just said it...
Or, perhaps I should not have said anything (since retro-variants are implied).

And, yes, for the record, I do mean there are retro-variants, within
an AP problem...

The point is somewhat technical, and I would prefer not to say too
much about it...
But, already, I have probably said too much :)

Best,
 Kevin.
