Thanks in advance, Tom Kieboom 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!

 How to compose a draughts problem by Serge YushkevitchAn 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.

 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.

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.

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.

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. Go to the Draughts working place #46! May

Goedemoed passed awayOn 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 RooijTriggered 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! Ad

The
MotifMine now also available on-lineThe 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 remaining hand-written carts into Word. Every three months there will appear an update of MM. (With thanks to Ad de
Hoon, who in 2015 came with the triggeing remark: "I miss the
motifs on the website.")
March  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.

Dijkstra wrote in De Problemist of October 2015
how he is working for making draughts problems: a concise recipe containing five ingredients! Worthwhile and instructive to be also seen on-line (in Dutch, with many diagrams). Which problemist is also willing to share his/her recipe? Send it to Tom Kieboom!
 Leen
de Rooij, recently became BSc! Sent enclosed motif, MM code 2001 10.30 (--) = -- (23), and asks for help to arrange it into a composition. See the Draughts working place #42.  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. Bron: Hein Wilsens, De Problemist december 2014, p. 167-169.
Showroom will be extended with photos of
the composersSince they may also be 'seen' together with their problems. See the first three examples: Oege Dijkstra, Leen de Rooij and Arie van der Stoep. Do you prefer a certain photo? Send it to Tom Kieboom!  Martin

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 'Letter problems'. 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! Rob Spijkers 
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?

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.

75, inspired Leen de Rooijand 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'. January  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. Tom Kieboom Counting Puzzle 
On the, imaginary, reception on behalf of the 75-year jubileeof 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. The outcome follows next week!

This webmaster's 75 logo symbolizes the eight beautiful compositions
that havebeen 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
firstfirst 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 duringthr analysis of a game he had played. Surprisingly, the combination was already presented in 1953 by a composition of P. Olivier!
