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)

        It contains a lot of information from the draughts literature and his own experience

    2016-10-17 Attention for visitors of web site! We invite draughts amateurs from all the world 

    to participate in the non-stop contest of the solution draughts ...

        Review of K.W. Kruijswijk's booklet (2013) 'Comments on 1001 Miniatures (1939)', after 75 years!

        Quite interesting complement for those who are a bit familiar with Dutch.

        (Source: Arne van Mourik, De Problemist August 2016, pp. 142-145, and archived at Notorious)

Will now also archive our KvD-website for permanent saving. Archiving will start from November19,  2016.
Thereafter, consecutive versions will be regularly filed. See the Dutch message of KB on the request of the webmaster.

    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.

De Problemist of October contains 40 pages with various problems, forcings, end games,
and articles including many diagrams and photo's, worth reading from start ...

... to finish:

    Father Wim Dopheide (1891-1975) in the Showroom

    Sent from his parish in former Batavia (Dutch Indies) a number of years
    problems to, of course, the catholic Dutch newspaper 'De Maasbode'.
    In Turbo Dambase you'll find another 65 compositions.
    (Source: Arne van Mourik)

        Herman Spanjer sent the failure on the left to Henk van der Heijden.

        Is repair possible?

        Go to the Draughts working place #48.

     Leen de Rooij made a trip to Albania and composed 
    there also a number of 'foreign' draughts problems.

    Enjoy the pictures and problems of his Dutch travel report. 


Back from football to draughts. Jaap Bus wrote recently about end games:

          Feyenoord the Greatest  (51.5x51.5x11.5 cm, 860 pp, 3275 photos, 30 kilogram)
            Prohibited Tom Kieboom to visit the KvD-reunion, as he made a substantial contribution
            for the first chapter of this giant book about Cor Kieboom (1901-1982), the legendary
            chairman of this football club, and has to be present during the festive presentation
            in stadion 'de Kuip', to transport that heavy book, to unwrap and to scroll through it:

Visit the KvD-reunion on Saterday, September 10. For complete information, click here!

Jaap Bus:

    After silence during the summer holidays, Leen de Rooij
    presents a beautiful composition that surely deserves a
    more well-balanced piece distribution.
    See the Draughts working place #47: who can help?

The front page of the August issue is followed by 38 pages with columns, stories and diagrams, ending with this back page:

    Tip: search function [Ctrl]+[F] for pdf-files
    Instead of scrolling, big pdf-files on the website like the Dictionaries and the MotifMine can

      New editor of the column Forcings Oege Dijkstra, because of the 
      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
        in De Problemist: Tjalling forced me to become a member"

(Source: De Problemist August 2016, page 128. English translation by Tom Kieboom)

5x5-miniature encore: can in mirror image be placed twice on the board
with first moves of white of the trio 18-13, 18-12 and 19-13, respectively

Holiday-5x5-miniature-strip with both 4 black and all 5 white pieces on shot*

Arised, again, by accident during an attempt to improve, in vain, a completely different problem.
Surprisingly, this jewel is not present in Turbo Dambase. Tom Kieboom, July 24, 2016.

* Concerning "All on stroke":  enjoy also the beautiful 8x7-miniature of Oege Dijkstra, in which white starts with all eight white men 
   on shot and does it again in the end with three white men and a king!

Hunt on the stroke record*: 5 black pieces on shot with 19 shot possibilities:
1x3x3x3x3x3x3x4x4x4x4x5x5x5x5x5x5x6x6 from a decent initial position,
with all nine white men on shot.
By accident, the 9x9 initial position of the left diagram 'felt' on the board.The center diagram shows the
chaos after white's move 27-22, resulting in the position with black on shot. White wins with single opposition.
How this curiosity did arise, after years' seeking for economic polystrokes, will be told later on in De Problemist.
Tom Kieboom, July 17, 2016.

* See the KvD-jubilee book of Arie van der Stoep, "Draughts with a wink", 2016, pp. 19-21 (in Dutch). The last record
   published is from Pieter Kuijper in De Problemist 9.1965, in which 5 black pieces have 10 shot possibilities.

The MotifMine

In digital form has been grown by Rob Spijkers during the last couple of
months and now contains 28,889 of his hand-written 54,493 motifs.

The parts 0, 1 and 2 have been further extended, part 3A is now added.
With fervent typing Rob hopes to finish part 3 at the end of this year!

From the collection of Wim de Zwart 15,560 new motifs were obtained.

As a homage to Jaap Viergever, one of the greatest draughts problemists ever, passed away in 2014, 
Leen de Rooij made eight arrangements on one of his motifs. 
You may see them on the sites of draughts club CTD Arnhem (, 
of the Limburg Draughts Society ( and of the draughts club VBI at Huissen (

On behalf of Leen de Rooij: "A nice start for fine holidays with hopefully good weather."

Jaap Bus:

"It is about 55 years ago that I made my first
46/5 and/or 5/46 compositions.
This article first shows a number of old ones,
followed by more recent compositions.
Though I, as contrast with the first one, give
a second Applet with a miniature forcing,
you will see a trend of reducing material
in recent years."


Arie van der Stoep

Simply allows black to catch six white pieces through 
a 1x2x2x3x3x3x6-stroke after a "Kieboom-startmove"
(as called by Pieter Kuijper in De Problemist of April
2016, page 49).

Not economic, the supporters of the Sharp Rules
will complain, while draughts players greatly will
enjoy such a moment of winning fast and sharp.

Remains the recurring question of the webmaster:
"Why, in problem making, is it allowed for white to
perform strokes without economy, but forbidden
for black to do so?"
More and more, people are getting in doubt of this SR.

        Janus Wuijtenburg
        Could create this peculiar intermediate situation, with white on move, 
        from a decent 11x11 start position.

        A moment supreme of contemplation: how to pass on?!

        View and play this composition in the Showroom (right diagram).

        Henk van der Heijden
        Started years ago, as draughts player, by composing problems.
        He doesn't hesitate to show many failures, which is quite 
        recognizable and instructive for both experienced and starting
        problemists. In Dutch, but you may still enjoy the diagrams and
        solutions given.

Blankenaar Endgames
Jaap Bus has wrote on his blog 'End games and more' an article about the so called “Blankenaar” endgames.
A Blankenaar is an endgame with only a few pieces (three White Kings against a King and a Man).
With mainly short combinations as variants.
The first Blankenaars are from the 19th century and the best of them are still very much worth to look at.
The solution of a Blankenaar can be quite complex, because of  the many possible moves of the White Kings
and the variety of the replies of the Blacks.
Even when using a computer program it is sometimes not evident how to select the thematic variants.
That is why I give some explanation. In particular for an extension of a Blankenaar I added to the article
because of a very surprising new variant.

Dream stroke

Arne van Mourik created from this position in a draughts
game a beautiful stroke combination towards gain!

Impressive example of how a 'draughts problem' may 
arise during and from a draughts game, taken place
recently during a Dutch draughts contest.

        Fake Timoneda's
        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?

            The webmaster has sent an arrangement to Leen,
            unfortunately again containing a side solution.

   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.
    Look and read further in the Draughts working place #44!

    Retrograde problems
    The natural interaction between game draughts and problem making.

     The reconstruction of a problem towards the initial position of a game.

      In order to show that a problem may easily occur from a game.

A number of examples is given on the new webpage 'Retrogade'.

(Thanking Ad de Hoon for the suggestion and input. Permanent link via 'Games')

    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.

       Jaap Bus
      "Ed Gilbert and I further investigated how to select interesting
        never published endgames out of the many billions of positions
        in the endgame databases.
        Now we present two spectacular examples of 4x 4 compositions
        without Kings at the start."

    Who would like to use the draughts board during Easter,
    may go to my column 'Easter eggs' on the sites: (draughts club VBI Huissen), (draughts club CTD Arnhem) and (Limburg draughts society).
    Fine Easter days!"

    Of course also webmaster's wish to you!

    Joost De Heer and Henk van der Heijden
    Inspired by Leen de Rooij's motif, showed  
    on facebook another three compositions.

    Ending in 'declining' motif code 2001 > 1001 > 0001.

    See the Draughts working place #43.

    Virmantas Masiulis succeded to make the best composition
    on the motif, 
MM code 2001 10.30 (--) = -- (23), of Leen de Rooij.

    See the diagram.

    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
    for making draughts problems: a concise recipe containing five ingredients!

    Which problemist is also willing to share his/her recipe?
    Send it to Tom Kieboom!

motif shown below of Leen de Rooij, thanks to facebook and e-mail!
See their results in the Draughts working place #42: improvement possible?
Virmantas Masiulis just sent in three compositions: see these next week!

    for help to arrange it into a composition.

    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.

On our facebook working place work has been
done on both combinations with white on shot.

The four-stroke of the left diagram could be 
arranged into a beautiful composition by
Leen de Rooij.

The six-stroke of the right diagram proves to
be much more difficult. See the working place.

    Showroom will be extended with photos of the composers
    Since they may also be 'seen' together with their problems.

    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

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'
('Draughts with a wink') by Arie van der Stoep: 90 pages with hundreds of diagrams curiosa.

Follow-up Draughts working place #37 and #38
    Leen de Rooij and Virmantas Masiulis have been busy to make compositions
    on these six motifs: see them in the working place!

    May-be, more beautiful compositions are possible on these difficult motifs?

Edvard Buzinskij
    Is not only a strong draughts player, but also known for his well-hidden 
    compositions in ordinary looking game-like positions.
    In his problems a certain stroke idea is the core of the composition.
    Whether it is sharp or not doen't really matter to him.
    Such compositions are also found in De Problemist, in the section 'Concrete' 
    of the column 'Draughts Problems' of Arne van Mourik.

Draughts working place #38
Leen de Rooij sent an improvement
of the three motifs #37 shown below.

See the draughts working place.

Can they be arranged into an acceptable
composition or is it a mission impossible?
Draughts working place #37
Leen de Rooij asks for help to arrange
these three motifs (black to move).
Preferably without a king in the initial
Leen only succeeded to make a
composition with a black king, but
contained a side solution.
        Go for inspiration to the Draughts working place. May-be, beautiful compositions are being created!

   = 75, inspired Leen de Rooij
   and sent a KvD-jubilee composition, ending in a motif with both pieces
    on the squares 5 and 15 (5x15 makes 75) and on 19 and 41 (starting year).
    The composition is shown on the home page ánd on the page 'KvD 75 years Jubilee'.


    Who knows a composition ending with a king shot 7x5,
    or can make it for our jubilee?

    Tom Kieboom couldn't find such a composition in Turbo Dambase.
    Reactions are wellcomed in the Draughts working place!
    By quick response, Leen de Rooij sent a 7x5-stroke composition: click here!

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!

Motif '19.41=20.16'
    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.

The Society of Draughts Composing: a consideration of 75 jears reunion
   A beautiful historic overview by Arne van Mourik.

    Although written in Dutch

Jubilee compositions
    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!

Tom Kieboom
    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.

New Year's wish by Henk van der Heijden
On 'his' KvD facebook there was this 1-January-2016
Nice 'loose' composition this time, whereby all the
Strong Rules have been neglected:
- one unneconomical two-stroke
- interchangable moves
- a not sharp ending
- an impressive phanthasy initial position.

Nevertheless, such a composition also deserves
publication: may-be, somebody is able to make
it better.
Draughts players don't mind those SR's, but will
be surprised by such an initial position.

It is simply the beginning of 2016 with some humor!
