It was quite hard, but I had to decide for personal reasons to stop as
webmaster of this site.
I've done it for several years with great pleasure and learned a lot.
Hopefully, a successor will be found soon: it's grateful work!
In the meantime, look for NEWS on Facebook
& Twitter
of the KvD. |

Once again, 40 pages full
with interesing articles,
problems, forcings and
end games, illustrated
with many diagrams,
photos and drawings! |

"This article is about a simple tool that might be used to teach young kids
and others who
want to learn more about playing draughts. In particular how to
calculate (simple) endgames.
I applied it long ago and rather
quickly the kids understood the first moves to be played and
how to
calculate a few moves ahead, till the chosen variant was completely clear to
them.
Finally they were very proud of being able to play all the
variants.
Maybe some of you can apply this tool as well.
At the end
it contains an adequate composition based upon the initial position of the tool." |

'Comfort with Timoneda'
During the momentary illness and after passing away of his wife Ria, Leen could find comfort with his draughts board.
We also compassionate intensively with his loss.

May
End Games and More
Jaap Bus (May 17): "This
second article on my Blog (the first a year ago) is about the very old type of endgames called "Blankenaars",
with a new look at this
genre applying the current rules concerning thematic variants.
For a number of readers of my Blog these complex Blankenaar endgames
will not be their favorites. However, even a quick look at it
will be enough to experience again the depth, complexity and beauty of our game."

After
the football party in Rotterdam, one should start working again.
Like making a decent composition on the
enclosed motif.

Martijn
van IJzendoorn winner Dutch championship 2017:
a brilliant stroke combination as example!
He played the most thrilling game the
last day. Although the junior-worldchampion
already had the title, Martijn went for full gain against Hein
Meijer.
That exemplary setting resulted in a memorable, unprecedented
spectacular duel,
that gave the position on the left, after move 34.
It is the introduction to a quite unusual and unbelievable stroke
combination,
with breakthrough to king. After five moves later, Martijn had won.
Just play it!

Arie
van der Stoep, April 7:
|
|
This
problem with a 1x3x4x6x7 initial stroke
Received the webmaster, who always loves this*,
as a present:
"Just now, my brain produced a problem inwhich white offers
7 (!) pieces by its first move: 42!, 41, 1, and always 1x49,
resulting in a new motif: (140) 40, 5+."*
I thanked Arie with the suggestion to add a preliminary bait move
38-32 (31-37?), but that made him not enthousiastic:
"We can ány problem present as bait move. I don't like
that."^
In
other words: bait move no, forcing yes!

44, diagram 45)

Arend Stuurman

Was already there with three beautiful problems in the Showroom,
from the top-81 of Ardjan de Jong.
This, however, contained another three beautiful compositions,
that have now been placed in the
Stuurman-affiliate of the
Showroom!
(P.S. By technical reasons the number of problems per composer
in the Showroom is restricted to three.
Therefore, affiliates are opened in order to show more problems of a
problemist. Links to affiliates
are found in the Showroom.)

Leen
de Rooij's e-mail of March 23 (translated):
"Inspired by a motif of Jan Scheijen and by the poem "May" of
Herman Gorter, I've made a series of
draughts problems
that fit the beginning spring.
I myself was very satisfied with this series, but, may-be, I'm not
really objective, search in 'nieuwe
lentegeluiden'." |

Jaap Bus'
e-mail of March 20:
The
topic of this article is a kind of nostalgic reminiscence for me of
a game
played long ago against one of the most remarkable draughts players
ever.
The game contains a number of interesting moments, in particular where
a
move that was not played would have lead to exciting variants.
*Can
be read ánd played on his site End games and more! |
Janus Wuijtenburg
Unexpectedly passed away, last December, on the age of 73.
Started rather late, when he was already fifty, with making problems:
all of a sudden there were full-grown and often fantastic
constructions that met the sharp rules, so proving the hand of
a master!
Hein Wilsens wrote an In Memoriam in De problemist of February
2017, including half a dozen beautiful draughts compositions
that can be now also seen, solved, and/oe played on-line with moving
diagrams in the 'Wuijtenburg-affiliate'.
Another three ones can be found in the Showroom. |

Jan Vink
Passed away last December on the age of 89.
Arne van Mourik wrote an In Memoriam in De
Problemist of February 2017.
Including a half-dozen creations that may be
considered as the most
beautiful ones composed by this topproblemist.
One was already there in the Showroom, the five
other ones can be seen,
solved, and/or played with moving diagrams in the 'Vink-affiliate'.

"The
last bastion of inertness has finally fallen:
At high pressures, about one million times as high as Earth's
atmospheric pressure,
helium and sodium form a stable compound with a three-dimensional
checkerboard-
like structure (see a part of it at the left). Sodiums are the purple
spheres, heliums are
the green cubes, and electrons are the red regions."

They cannot be judged by the

they are living next to and not within the problemism. Enjoy the most
wonderful scenes.

Hub
Simons' request* (as English summary):
More
than two years ago, Hub Simons succeeded Hein
Wilsens as editor of the column 'Problemism' in the
Dutch draughts journal 'Hoofdlijn'.
While many problemists send their compositions to
De Problemist
for publication, just a few of them send
their work towards Hoofdlijn.
Therefore, other problemists are
wellcomed very much
for publication in my column too.
Please, consider sending your problems by e-mail to
hub-simons@ziggo.nl
and let the readers of Hoofdlijn^
also enjoy your work!
(*As
'guest speaker' of the problems column, De Problemist
of December 2016)
In the enclosed
issue of Hoofdlijn, Hub Simons can write:
In addition to the wellknown names, there are
two new-
comers, Tom Kieboom and Valdas Bieliauskas. I hope to
see more material from them in the future.
^
On
the question of the KvD-webmaster "How started Hoofdlijn?",
Herman van
Westerloo mailed on December 14, 2016:
"About 28 years ago, Harm
Wiersma invited Nico Leemberg
and me in Amsterdam with the proposal to start this journal."
Since
then, these three founders still form the editorial board of
Hoofdlijn, so more than 200 issues long!

KvD-facebook
Has been visited recently again quite frequently and used to share new
poblems.
These fresh creations may and are replied in short time with comments
by collegues,
and in a number of cases foreseen of suggestions for improvement.
In this way, it is a rapid and efficient Showroom &
Draughts working place, a very nice
compliment of those on the KvD-website!
Become also follower of KvD-facebook: signing up can also
at Henk van der Heijden.
The simple, beautiful, example on the left is from the 'facebookmaker'
himself,
January 19, 2017, that was improved by Joost de Heer within
one day by transferring
the white man 48 to 47. Also small changes can be of importance! |

Polymer-stroke-choice
A somewhat out-of-control hobby of the KvD-webmaster.
After a series of 6-, 7- and 8-stroke-choices, now a 9-

working place,
for further possible revision.

Two
débutantes in problemism
|
Gerard
Benning
|
Last
month, two new problemists presented
themselves:
Gerard Benning
in De Problemist of December 2016
(Arne
van Mourik's remark: No surprise that white and black
work towards
a 2 by 3". The solution will appear in
De
Problemist of April 2017.)
Evert Evers in the
Reformatorisch Dagblad of
December 27, 2016
(Martin van Dijk's remark: It's always
nice if a solver makes a problem maakt. Evert comes with a
successful debut, based on a draughts game.
See
the solution of RD January 17, 2017.) |
Evert
Evers
|
Eric van Dusseldorp |
Two
opposite curiosa
Eric van Dusseldorp created an
11-man-stroke, including a retrograde
from the 20x20 starting position.
Oege Dijkstra made a poblem with
eight times a one-shot.
Scroll through the webpage Curiosa and
see both records* down under!
(* Still
other records known?) |
Oege Dijkstra |
 |
Tom
Kieboom
Has made an 11x11 arrangement on the
forcing of Michiel
Kroesbergen in order to get a sharper ending (diagram).
See the Draughts working place #51.
Quite ugly but how sharp?
Right on the board, both white and black cannot really move.
At the left-hand side, white wins with piece 48 through
opposition,
after black's move 6-11, that is not absolutely sharp, unfortunately. |
Michiel Kroesbergen
Editor 'PARTIJPROBLEMATIEK' (Game-problemism)
of Het Damspel (The
Draughts game),
asks for help to arrange
his probleem, based on a game-combination, towards a sharp
end.
Look, read and work further in
the Draughts working
place #51.

Timoneda
motif
Even 8,440 times used as an ending
of a draughts composition! But there
are more than 50,000 other motifs. |
MotifMine
 Is extended last year by Rob
Spijkers
towards 56,129 motifs, of which now
35,034 can be searched on the site.
The parts 0, 1, 2, and 3A increased,
a new part 3B has been added.
Robs retrospect (in Dutch)
contains
interesting data of the growth of
the MotifMine,
from 2007 till now.
70-year old Rob expects to be busy another three years to
complete
the MM in digital format and is insistently seeking a
successor.
Who is willing to contact
him?
