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. Todorović, Goran Škare, Igor Spirić, Joza Tucakov, Marjan Kovačević, Mihajlo Milanović, Milan Velimirović, Miodrag Radomirović, Mirko Miljanić, Nikola Miljaković, Nikola Petković, Petar Opening speech: Milan Milićević, president Šoškić, Radomir Mićunović, Slobodan of Chess club “Beograd Beopublikum”, Šaletić, Stevan B. Bokan, Tomislav Petrović, accompanied by Marjan Kovačević Vladimir Podinić and Zoran Sibinović. The programme was very busy and here is a brief report of all the events. Friday, May 2nd, 16:00.

Dutchman Who Did Not Drink Beer. He Also Surprised My Wife Nina by Showing up with Flowers at the Lenox Hill Hospital Just Before She Gave Birth to My Son Mitchell
168 The Bobby Fischer I Knew and Other Stories Dutchman who did not drink beer. He also surprised my wife Nina by showing up with flowers at the Lenox Hill Hospital just before she gave birth to my son Mitchell. I hadn't said peep, but he had his quiet ways of finding out. Max was quiet in another way. He never discussed his heroism during the Nazi occupation. Yet not only did he write letters to Alekhine asking the latter to intercede on behalf of the Dutch martyrs, Dr. Gerard Oskam and Salo Landau, he also put his life or at least his liberty on the line for several others. I learned of one instance from Max's friend, Hans Kmoch, the famous in-house annotator at AI Horowitz's Chess Review. Hans was living at the time on Central Park West somewhere in the Eighties. His wife Trudy, a Jew, had constant nightmares about her interrogations and beatings in Holland by the Nazis. Hans had little money, and Trudy spent much of the day in bed screaming. Enter Nina. My wife was working in the New York City welfare system and managed to get them part-time assistance. Hans then confided in me about how Dr. E greased palms and used his in fluence to save Trudy's life by keeping her out of a concentration camp. But mind you, I heard this from Hans, not from Dr. E, who was always Max the mum about his good deeds. Mr. President In 1970, Max Euwe was elected president of FIDE, a position he held until 1978. -

Chapter 15, New Pieces
Chapter 15 New pieces (2) : Pieces with limited range [This chapter covers pieces whose range of movement is limited, in the same way that the moves of the king and knight are limited in orthochess.] 15.1 Pieces which can move only one square [The only such piece in orthochess is the king, but the ‘wazir’ (one square orthogonally in any direction), ‘fers’ or ‘firzan’ (one square diagonally in any direction), ‘gold general’ (as wazir and also one square diagonally forward), and ‘silver general’ (as fers and also one square orthogonally forward), have been widely used and will be found in many of the games in the chapters devoted to historical and regional versions of chess. Some other flavours will be found below. In general, games which involve both a one-square mover and ‘something more powerful’ will be found in the section devoted to ‘something more powerful’, but the two later developments of ‘Le Jeu de la Guerre’ are included in this first section for convenience. One-square movers are slow and may seem to be weak, but even the lowly fers can be a potent attacking weapon. ‘Knight for two pawns’ is rarely a good swap, but ‘fers for two pawns’ is a different matter, and a sound tactic, when unobservant defence permits it, is to use the piece with a fers move to smash a hole in the enemy pawn structure so that other men can pour through. In xiangqi (Chinese chess) this piece is confined to a defensive role by the rules of the game, but to restrict it to such a role in other forms of chess may well be a losing strategy.] Le Jeu de la Guerre [M.M.] (‘M.M.’, ranks 1/11, CaHDCuGCaGCuDHCa on ranks perhaps J. -

In Received 20 September 2009 particular, some games have such an immense state space and high degree of uncertainty Received in revised form 4 April 2010 that traditional algorithms and methods struggle to play them effectively. Monte Carlo tree Accepted 4 April 2010 search (MCTS) has brought significant improvements to the level of computer programs Available online 9 April 2010 in games such as Go, and it has been used to play partial information games as well. Keywords: However, there are certain games with particularly large trees and reduced information Games in which a naive MCTS approach is insufficient: in particular, this is the case of games Chess with long matches, dynamic information, and complex victory conditions. In this paper we Kriegspiel explore the application of MCTS to a wargame-like board game, Kriegspiel. We describe and Incomplete information study three MCTS-based methods, starting from a very simple implementation and moving Monte Carlo tree search to more refined versions for playing the game with little specific knowledge. We compare these MCTS-based programs to the strongest known minimax-based Kriegspiel program, obtaining significantly better experimental results with less domain-specific knowledge. © 2010 Elsevier B.V.
