Jan van Tol, 1987 (?)

(Uit m'n hoofd, vandaar dat ik niet zeker ben van het jaartal. Misschien stond 49 op 50).
1. 17-12 7-11
2. 49-44 18x7
3. 32-28 23x32
3. 31-27 32x21
4. 26x6


Image

Zwart kan (5-10) 15x4 (34-39) proberen. Dat verliest door 4x1 (39x50) 1-12.

Het enige serieuze alternatief is

4. ... 7-11
5. 6x17 13-18
6. 17-11 18-22
7. 11-7 22-28
8. 7-2 28-33
(28-32 eindigt na 2-24 in drievoudige oppositie)
9. 2-16! 33-39
10. 44x33 34-40
11. 16-49 40-45


Image

12. 49-32! 5-10 (want 45-50 32-14 )
13 15x4 45-50
14. 4-10!
en zwart mag voor het laatst kiezen.

Dit fraai en veel varianten miniatuur ik toewijd aan mijn vriend Yuri Chertok (31.01.1957) naar zijn 50-jaaren.

Het klopt allemaal precies. Na 14-10 39-43 10-5 kan zwart niet promoveren wegens damafname, maar hij kan ook niet blijven staan vanwege de dreiging 42-38 43x32 12-8.
Op de zevende zet sluit zwart zijn dam noodgedwongen tijdelijk op, zodat wit met 8. 5-10 een tempo kan verliezen.
En 9. ... 49-40 verliest door 50-44 40x10 5x50

Inderdaad prachtig. En dan te bedenken dat De Problemist boordevol van dit soort hoogstandjes staat, zeker sedert Arie van der Stoep hoofdredacteur is geworden. Nog geen abonnee? Schande....

A. van der Stoep, Hoofdlijn mei 2006

Is dit nu een partij-achtig standje? Nee, niet echt. Toch zijn de laatste zetten 19-14 (13-19) best geloofwaardig.

Zwarte schijven op 1 en 6, dat zou wel eens op een Guerra kunnen uitlopen.

1. 14-9 (19x28) 2. 17-11 (6x17) 3. 16-11 (17x6)
Het kost twee schijven maar dan heb je ook wat: ruimte voor de komende dam.

4. 9-3 (8-13)

Image

5. 3-26 (31-36) 6. 26-17 (36x47) 7. 17x15

Image
(zwart aan zet)
7. ... (47x20)
8. 15x8! (30-34)
9. 35-30 (34x25)
10. 8-2

A. van der Stoep, De Problemist december 2006 (rubriek Forcings)
(wit 29,34,35,39,44

1. 39-33 (14-19) 2. 44-40 (20-25) 3. 29x20 (25x14) 4. 33-29 (14-20) 5. 29-24 (19x39) 6. 40-34 (39x30) 7. 35x15-10-4-10-15x38-33-50.

Mooi klein ding.

There's no exact variation in this version. After (32), both 4-13 and 19-14 win. And (35)4-13(40C)30,02 C(35-30)40 isn't exact either (there's choice for the final capture).

    Just an idea ... there is alot of negatives in this position:
    - non-economic red jumps in final;
    - alternative white jump 35x24;
    - red man on 44.

    Only one positive thing - beauty [img]http://laatste.info/bb3/images/smilies/icon_lol.gif[/img]

    Don't be shy, your composition is completely correct.
    1. 'Non-economic' is not a problem in a final position ('motief' in Dutch).
    2. Alternative white jump: in the Netherlands we call it a 'molenwiekslag'. Not very nice when a king can alternate, but a molenwiekslag with a piece is for 90% of the problemists not a problem.
    3. Red (in my country black/zwart) man on 44. Nothing wrong with it in a composition.

    You've created a nice problem. Congratiulations!

    Eric

    Eric, thanks for kind words ! :P It was very interesting and educatable for me to learn from your post Netherland requirements to composition. It seems like they are not as strong and restrictive, as Russian rules, which I learned many years ago before immigrated to USA in 1991.

    I called "red" pieces instead "black" (also usual in Russia), because it is used in the most recent American English Draughts media due to "political correctness" :roll:. Even more - most modern checkers sets in USA today have red and white pieces, in different with black and white 20 years ago !

    Here is another miniature:
