The Retter 80JT Tourney award is on page 4. award is on page 2 1 Yosi Retter 80 Jubilee Tourney Award Judge: Yosi Retter, Jerusalem Requested were selfmates in 2 or 3 moves showing the Feldman-I theme. This theme involves reciprocal continuations after random and correction moves of two black units. Cyclical presentations involving three (or more) black pieces were also allowed. The theme was difficult to implement and I was not expecting to receive many problems. Alexander Kuzovkov I received 27 problems in anonymous form, which is a reasonable number. 1st Prize The level of the problems, and the first four in particular, was very high. Retter 80 JT 2016 1st Prize: Alexander Kuzovkov 'd'd'dBd I was doubtful whether the theme could be implemented with three thematic d'0'dnd' pieces and a cyclic mechanism. I was glad to find out that this is indeed 'dPg'd'd possible. Here there is a combination of twice line openings and self-blocks $pd'dQd' and once line vacation and line closure. These are known elements, but their NdPi'd'd combination is a great achievement. 1.Se1! zz 1...Bd~ 2.Qf4+ A Be4# dpdN0'0' 1...Be5! 2.Qd3+ B Bxd3# 1...b5~ 2.Qd3+ B Bxd3# 1...bxc! 2.Rd2+ C p)'d'dRd Bd3# 1...S~ 2.Rd2+ C Bd3# 1...Se5! 2.Qf4+ A Be4# 4bI'd'G' 2-3rd Prize: Alexander Kuzovkov S#2 11+11 The correction moves cause black obstructions. In the thematic tries the Hannelius theme is performed. The only shortcoming is the weak key, which seems impossible to improve. 1.Se3? Rxc5! 1.Sf2?

After the correction moves a Zugzwang is created, which is also surprising. 1.Rf8! zz 1...B~ 2.Sec4+ A Bxc4 3.Qd4+ Bxd4# 1...Bxd5! 2.Sxg4+ B Ke6 3.Sxd5 B~# 1...R~ 2.Sg4+ B Rxg4 3.Qd4+ Bxd4# 1...Rg6! 2.Sexc4+ A Kf5 3.f7 B~# 1...fxe3 2.Sd7+ Kf4 3.Qxe3+ Bxe3# 4th Prize: Sven Trommler Random moves of the black pieces create a flight, whereas the correction moves create an additional flight. In this problem as well the idea seems original. 1.Rf8?

The correction moves unpin the black queen. The tries are refuted by the prevention of one of the thematic mates after a correction move.

  • B. G. Laws: the Artistry of the Chess Problem (1923)
    The Artistry of the Chess Problem with special reference to the beauties of the three- and four-mover by B. G. Laws [ 1923 ] An Electronic Edition Anders Thulin, Malmö 2008-04-12 NOTES TO ELECTRONIC EDITION The main change in this edition is the use of modern algebraic nota- tion, using the letter ‘S’ to represent the knight. The notation used in the original is a mixture between algebraic and descriptive. All problems have been computer tested – any inadvertencies have been documented in brackets in the solutions. Some minor notation mixups have been silently corrected. The obvious misprint of a white Queen instead of a white Rook on d2 in the Geyerstam three-mover has also been corrected, as well as the name of the creator of the Indian problem, which was given as Rev. C. Loveday. One oddity was discovered during testing. The Chocholouš four- mover lacks a solution: it turns out that it appears here in a different form than that it was originally given. The reason for the change is not known. The original form is as follows: cuuuuuuuuCG. Chocholouš {WDWDWDKD} {hWDWDWHW} {WDWDWDWD} {DPDWiW0N} {WDWDWDW)} {DnDQDWDW} {W4WDWDWD} {DWDWDWDW} vllllllllVMate in four BEAUTY IN THE THREE-MOVER By B. G. Laws In considering the Chess Problem with a view to appreciating its qual- ities, three essentials must be borne in mind: difficulty, idea and con- struction. Each of these is complementary of the others. Difficulty is placed first mainly for the purpose of disposing of that subject before dealing with the other two. It can hardly be suggested that there is beauty in this quality considered alone; but the causes which create this feature may be beautiful, such as the latent chess truth being ob- scured by skilful deployment of the men.

  • The 5Th Belgrade Chess Problems Festival Report by Milan Velimirović the Fifth Successive Festival Took Place from 2Nd to 4Th of May 2008
    Mat Plus Review Summer 2008 The 5th Belgrade Chess Problems Festival Report by Milan Velimirović The fifth successive Festival took place from 2nd to 4th of May 2008. As usual a good number of guests from abroad were welcomed: Dinu-Ioan Nicula (ROM), Aleksander Leontyev (RUS), Andrey Selivanov (RUS), Eric Huber (ROM), Fadil Abdurahmanović (BIH), Iļja Ketris (LAT), Ivan Denkovski (MAK), Kostas Prentos (GRE), Michal Dragoun (CZE), Piotr Murdzia (POL), Valery Kopyl with his lovely daughter Valeria (UKR) and Živko Janevski (MAK). You may have noticed the exception from the alphabetical order of that list, but there is a good reason for it: Dinu-Ioan Nicula is the only foreign composer who has attended all five Festivals, and if he comes again next year the organizers could consider the idea of promoting him into an honorary participant. Anyway, all guests have been treated by the home team in a traditionally warm and friendly way. For the record, the participants from Serbia were: Bogoljub Trifunović, Borislav Gađanski, Borislav Ilinčić, Božidar Brujić, Božidar Šoškić, Branislav Đurašević, Darko Šaljić, Dragoljub Đokić, Goran Janković, Goran M.

  • Yanofsky, Daniel Abraham (”Abe”) (26.03.1925 - 05.03.2000)
    Yanofsky, Daniel Abraham (”Abe”) (26.03.1925 - 05.03.2000) First Canadian Grandmaster ever. Born in 1925 in Brody, then Poland, he arrived the same year in Canada, as an eight months young baby. A child prodigy. Brilliant technical play, especially in the endgame. Prominent Winnipeg lawyer and city councillor, Winnipeg, Manitoba, and Mayor of West Kildonan, Manitoba. Awarded the IM title in 1950 (the inaugural year), the GM title in 1964 and the International Arbiter title in 1977. The first chess player in the British Commonwealth to be awarded the Grandmaster title (Apart from German-born chess player Jacques Mieses who moved to England in the 1930s to escape Nazi persecution as a Jew. Mieses became a British citizen late in life, then received the title when FIDE first awarded the grandmaster title in 1950, Mieses was one of the 27 original recipients, and the oldest of them) Yanofsky was British Champion in 1953 and Canadian Champion on eight occasions: 1941 in 1943, 1945, 1947, 1953, 1959, 1963, 1965; his eight titles is a Canadian record (tied in closed tournaments with Maurice Fox). “Little Abie” or “Abe”, as the local newspapers called him soon, was a Child Prodigy. At age of 12, Yanofsky won the championship of Manitoba. He repeated every year through 1942, when nobody else even bothered to show up. Thereafter, Yanofsky was banned from further participation in the Manitoba provincial championship to encourage others to play in it :) At 14, was picked to play at board 2 for the Canadian Team in the Olympiad in Buenos Aires 1939.

  • Glasblåsarens Pojke
    Ingemar Johansson: Glasblåsarens pojke Gideon Ståhlberg 100 år För drygt 100 år sen, den 26 januari 1908, föddes i Surte (strax norr om Göteborg) en pilt som skulle gå till schackhistorien som Sveriges förste internationelle stormästare. I dopet fick han namnet Anders Gideon Thome Andersson-Stålberg – så småningom förenklat och förädlat till Gideon Ståhlberg. Släkten tycks ursprungligen ha varit självägande bönder i Nödinge församling, men i dyningarna efter laga skiftet 1845 och framväxten av en glasbruksrörelse i Surte sökte sig fadern Alfred Andersson (född 1854) till bruket och avancerade från glasblåsare till föreståndare för buteljframställningen och så småningom förvaltare på bruket. Det var en upphöjd position. På äldre dar skulle sonen Gideon gärna excellera i deklamationer av Gustaf Frödings dikter. En av de mest kända är ”Den gamla goda tiden”, där det bl.a. heter: ”Min käring har svälten knäckt, min dotter är brukets skarn, förvaltaren själv är släkt med stackarens första barn.” Frödings miljö är givetvis ett värmländskt järnbruk, men hans rader säger det mesta om bruksförvaltarens sociala ställning vid denna tid. Familjen hörde således till det lilla brukssamhällets toppar och det prosaiska Andersson förbyttes omsider till Stålberg och – som kronan på verket – Ståhlberg. Gideon visade tidigt läshuvud och bestods en ordentlig utbildning. År 1917, vid pass nio års ålder, skrevs han in på Högre Realläroverket för Gossar i Göteborg, Nio år senare lämnade han det med en studentmössa på huvudet. ”Hur det nu gick till”, raljerade Ståhlberg senare. Några betydelsefulla saker hände däremellan. En var att Gideon blev faderlös 1919, en annan att intresset för schack väcktes. Senare skulle han själv berätta hur fascinerad han blev av tidningarnas schackdiagram i samband med Nordiska mästerskapen 1917.

  • Chess Festival
    Boris Gelfand’s Remarkable Comeback Yochanan Afek reports back from the star-studded Netanya International Chess Festival A big International Festival was organised in the coastal Israeli city of Netanya by the Israeli Chess Federation and the local municipality, supported by the generosity of businessman Roman Abramovich, likely best known to the readers as the owner of Chelsea Football Club. It has been quite a while since Netanya last hosted a strong international chess event, but the city has a long and respectable tradition of grandmaster tournaments. They were initially part of the popular Schach-Kait (Chess & Holiday) festival. Over the years various master tournaments were held as well as many editions of a grandmaster crown group, whose winners included the world- class icons Bobby Fischer (1968), Sammy Reshevsky (1969), Lubomir Kavalek (1971 and 1973), and Jan Timman (1975), as well as local heroes Yair Kraidman (1964) and Moshe Czerniak (1965). Played in the VIP room of the city’s Ilya Smirin might be in his fifties, but still produces plenty of attacking and exciting games. football stadium and consisting of two major sections, this year’s edition of the Netanya International Festival was both the biggest beaten in just 25 moves by Tamir Nabaty, 66 g5!

  • Chess Problem Composing Steps
    Appendix A Chess Problem Composing Steps Chess problems for this research were composed automatically using CHESTHETICA (see Fig. A.1) following the essential steps below. It is a modi- fication of the approach used in (Iqbal 2011). The problems composed are limited to orthodox mate-in-3 problems in standard international chess. 1. Obtain the two new DSNS strings produced from the DSNS process (see Sect. 3.1). 2. Set the total number of white pieces and black pieces that can be used in the composition. There are two attribute values pertaining to these features in each DSNS string. (a) For example, if in string 1 the white piece count is 5 and in string 2 the white piece count is 10, the range possible for this computer composition is between 5 and 10. The same for the black pieces. 3. Calculate the total Shannon value of the white pieces and then the black pieces in both strings and get the average of each. Use these average values to determine the number of piece permutations (i.e. combinations of different pieces) that satisfy them. (a) For example, an average value of 10 for white could mean having a bishop, two knights and a pawn whereas an average value of 9 for black could mean having just a queen. The total number of piece permutations possible for both the white and black pieces here is totaled. (b) This total will equal the number of times the same pair of DSNS strings is used in attempting to generate a composition. So, in principle, every legal piece combination can be tested.
