Protest-problem against the sharp rule 'economic stroke': 39-33 with 5-stroke by black, followed by 48-42 etc., ending
in a motif that's sharp according to Rob Spijkers. White must go, after black's 21-27, with the king on 47 to 36 in order
to win! Arie van der Stoep also made a 'protest-problem' with a non-economical 6-stroke, see his third problem in the
Showroom of the KvD-website. (Source: Tom Kieboom, KvD-facebook November 17, 2016)
How to compose a draughts problem by Serge Yushkevitch
An international contribution of our editor from Ukaine to this series in De Problemist.
It contains a lot of information from the draughts literature and his own experience
about the various ways a draughts problem arises from, i.e.:
where the inspiration might come from as well as the techniques that have been used.
(Source: De Problemist August 2016 pp. 114-117 and the webpage Componeren/Composing)

that was recently used by Lithuanian draughts players for an international
on-line solution contest: "this one is nice and good work!"

Pieter Kuijper couldn't make a choice of which problem should be included as
third problem in the Showroom and sent several compostions to the webmaster.
Also he couldn't choose and opened, therefore, a so-called 'Kuijper-affiliate' of the Showroom.
May-be, more 'personal' affiliates will be opened in the future, of/by someone else?
Ardjan de Jong gave previously the webmaster the golden tip for moving diagrams on the website.
Through teacher Eric van Dusseldorp, this could be realized, followed by fantastic help of Klaas Bor to
upgrade the after some years aged applet into a modern fashion.
A third, beautiful, problem of Ardjan is now added to the Showroom.

sudden death of Tjalling Goedemoed:
"I didn't want to write this column, as Tjalling had to do that. For many years, he was
crucial as promotor of (game)problems. Rare to say in this respect: he was immortal.
He brought me into the world of the problemists. In 2010 I published my first composition

How this curiosity did arise, after years' seeking for economic polystrokes, will be told later on in De Problemist.
Tom Kieboom, July 17, 2016.
Could create this peculiar intermediate situation, with white on move,

Contain in the initial position black pieces on 1, 6 and 25, but don't end
by the Timoneda-motif. According to Leen de Rooij, 'De Problemist' has
organized a composition contest on this, about 50 years ago.
Who knows more about it and can give information to the webmaster?
Arie van der Stoep sent an e-mail with this information: "Derk Vuurboom, since circa 1953
editor of the Dutch newspaper 'De Waarheid' organized an international composition contest
on this sly joke, see De Problemist 1.1954 p. 3. I know this as I have collected those problems."
Leen de Rooij
Presents this time the accompanying stroke system,
for which the two kings and piece 41 has to be
moved to the right positions.
Unfortunately, his arrangement contains a side solution.
Who is able to make a better problem on this?

Tjalling Goedemoed passed away
On May 10, 2016 we received the very sad message that
the draughts world has lost one of its greatest draughts
promotors, a great man and draughter, on such a young age.
The desperation is enormous, everywhere!
An In Memoriam will appear in De Problemist of June.
As inheritance, Tjalling finished for us at the end of 2015 the
final version of his impressive book 'The art of winning', an
enduring commemoration to this draughts coryphaeus whom
life eventually expired by 'The fate of losing'.
Our sympathies go to the family, friends and acquaintances. The website stood respectfully still for some time.
Leen de Rooij
Triggered quite some work in the Draughts working place by his request to
arrange the difficult motif 0111 --(14) = 25(46) into an acceptable position.
Even seven compositions have been made.

The MotifMine now also available on-line
The collection motifs of Rob Spijkers (53.149 data) is now for
almost half (26.400 data) to see on the website.
With the MM-code, motifs may be easily found or checked if
a certain motif has been published already before.
With a speed of about 50 motifs per day Rob is typing his

How a draughts problem is created by KvD-facebook?
Firstly, a trigger of a rather difficult to arrange 6x4-stroke combination, thereafter
a nice pass "for further inspiration?", that finally could be utilized to make the goal!
See the Draughts working place #41.
"Ed Gilbert and I further investigated how to select interesting
never published endgames out of the many billions of positions
in the endgame databases.

Leen de Rooij
“Dear draughts friends,
Of course also webmaster's wish to you!

All arrangements of this motif, including that of Leen de Rooij himself,
are now shown in the Draughts working place #42 and can be played.
Oege Dijkstra wrote in De Problemist of October 2015 how he is working

Jacob Barend Sluiter jr.
Had a rather remarkable appearance: he dressed himself neatly, even a bit artistic.
Was a real gentleman amongst the often somewhat slovenly draughts folks.
This strong draughts player also made some tenfolds of beautiful problems.
Three have now been included in the Showroom.

Ad de Hoon, inspired by the KvD jubilee book "Draughts with a wink"
by Arie van der Stoep, came with the suggestion to open a webpage
In addition, he sent an extra number of examples.
A first draft of such a webpage has now been made!
Leen de Rooij has made a goal on his own assist
of the motif given below, as submitted by Rob Spijkers.
However, Henk van der Heijden did found a side solution. Shit!
Virmantas Masiulis, as magician, repaired that in a unique simple way.
A fantastic example of the webmaster's column in De Problemist
"How a draughts problem is arising?". See the Draughts working place #40.
Are there still other goals possible on this difficult motif? A game-like position is not required, is not possible!
Received this motif from Eddie van de Acker.
It is unknown Turbo Dambase and Motif Mine.
The motif has two really sharp solutions, but Rob
didn't succeed to arrange it properly.
"Who will and can?" is his question in the Draughts working place #39!
Leen de Rooij gave there a very nice assist. Who will make the goal?
can be read fully on-line, this time! May-be, it is also the right time to subscribe?
Members of KvD have also received the jubilee booklet 'Dammen met een knipoog'

Solution Counting Puzzle: how many handshakes at a reception of 64 people?
Ionica Smeets (culumn 'Ionica saw a number', de Volkskrant January 9, 2016)
explained it by a story. The 1st person cannot give a hand shake (0),
the 2nd only 1, the 3rd gives 2, etc., the last one 63. So, the total appears to be
1+2+....+63 = 63x64/2 = 2016, the KvD jubilee year.
As an alternative, one may use the general mathematical formula H = (N-1)xN/2,
with H = number of hand shakes, and N the number of persons.
Rob Spijkers used this formula and was right, Leen de Rooij judged a 'bit high' with
64x63 = 4032 (63 as one cannot give himself a hand shake), but forgot to correct
for double counting: 4032/2 = 2016 (i.e. 1 hand shake = 2 hands).
A more difficult question would have been: "How many persons were on the reception if there were 2016 hand
shakes given?" In that case one should solve N from the quadratic equation "NxN - N - 2xH = 0" for H = 2016.
Mathematics is also a useful tool in draughts, both games and compositions. For example, the number of motifs
of 2 black and 2 white men (as given below): Nx(N-1)x(N-2)x(N-3)/2, with N=45, is 1,787,640!
Seemed at first sight sharp according to: 1.19-13 20-24 2.13-9 24-29 3.9-4
29-33 4.4-22 33-38 5.22-39 16-21 6.39-48 21-27 7.41-36 27-32 8. 36-31+.
I doubted, however, and placed the motif on our facebook for response.
Pascal Stil agreed that the first five moves were sharp, but that white after
5. .... 16-21 also can win with 41-37 followed by 39-25, 39-30 or 39-34.
Also after black's move 6. .... 21-27, white can win by various moves.
Reason to call it 'Fireworks arrow': five sharp moves with a scattering ending.
Rob Spijkers judged it, nevertheless, worthwhile to include it in the Motif Mine.
On the, imaginary, reception on behalf of the 75-year jubilee
of the KvD, there were 64 draughts problemists present.
How many hand shakes have been given to each others?
Solutions, including the way it was found, may be sent to Tom Kieboom.

This webmaster's 75 logo symbolizes the eight beautiful compositions that have
been created for the 75th birthday of the Society of Draughts Composing (KvD).
Upon a former request, Tjipke Smedinga has made a quartet of compositions,
ending in the naturels 19, 41, 20 and 16, respectively, while both Hein Wilsens
and Leen de Rooij created compositions with a jubilee-year end-stroke 20x16,
as well as, rather wild, compositions ending in the jubilee 27/48 (=75) motif.
Our thank is great: see and enjoy these compositions!
Is the first one of the new year in the Draughts working place with a first
first attempt to create an acceptable composition on a new motif with
MM code 3010 24.30.35 = 06 (--) with white to move.
Unfortunately, black last move 10-15 does pain in the eyes!
A request for improvement was also placed on our facebook with a fast
and surprising result: within a few hours, Leen de Rooij made two really
beautiful composition (in the blind!).
Click here to take a look to this result!
The Olivier system
Michiel Kroesbergen did find in 2007 a beautiful combination during
thr analysis of a game he had played. Surprisingly, the combination
was already presented in 1953 by a composition of P. Olivier!
However, there were a number of shortcomings in this composition,
and in some later attempts by others.
Reason for Arjen Timmer dig further on this combination system,
together with a challenge to colleague problemists to make a real
beautiful composition. With success.
