Hi Hirokaz,

Congratulations on your recent prolific output.

I haven't been tracking this thread, but your QB8 promotion caught my
eye as being slightly longer than the others in the mail, so I wondered
if I might have a chance to sneakily improve it. Here is my version of
your composition:

SPG 8.0

But I realize that I don't understand what you are doing, because if a
mating pawn move on a given 8th rank square is your only objective,
then it can trivially be achieved much more quickly, e.g.:

SPG 4.5

which has the additional advantage that there are no extraneous
promoted pieces on the board.

There is a general point here. The huge PDB database is a wonderful
resource for retro and other composers. But one problem I encounter
there is that usually no indication exists for the motivation for a
particular composition (e.g. what were the objectives for a particular

There is a subtle theft of meaning which takes place, which robs the
composers of the full credit for their achievement.

Of course one can say that it's hard or impossible to specify *all* the
criteria which a composer has to satisfy, some of which are very
subjective. Yes, but that doesn't imply we should be silent here.

Or one might say that a great problem is self-documenting. No
explanation should be necessary. Yes, but not all problems in PDB are

I think that the objectives for a problem should form part of the
problem's full documentation as stored in PDB. As part of that, we
should attempt to capture the announcements of all tourneys and tasks
which are referenced in PDB.

And I would encourage any composers publishing here in the retro
mailing list to state what their full objectives.

Best regards,
Andrew Buchanan.
