Dear retro friends,

With the birthday tourney of Thierry Le Gleuher, there

were new records in problems with "Add pieces" stipulation.

I was interested enough so as to start a compilation of

this kind of problems. After some thoughts the possible

categories seem to be:

* Type A : no king in check

Type C : at least one king in check

Type ? : the color of the piece to add is given

Type ?? : the nature of the piece is given

* The number of pieces is given ("add N pieces")

The number of pieces is not given ("complete the position"

* For "add 1 piece" and "complete" (+1), nature of the piece

* Diagram with or without promoted men.

Here are the records has pointed out by Nikolai Beluhov on

the problem database, and some more.

Maximum number of pieces to add (9) for a legal position, Type C

or economy records for "complete the position" (+9) Type C

I'm quite willing to make a booklet with the results of the

hunt for such records. For the moment the categories to

include are unclear in my mind, except for

"Complete the position" (+1) type A/C + nature

"add 1 piece" type A/C + nature

Economy records for "complete the position" (+N) type A/C

Which makes for at least (6+6+10)*2 problems to find.

Any comments (and new records! ;) are welcome.

Best regards, Alain
