Bleicher Reading, U.K., Deventer, the Netherlands and Berlin, Germany ABSTRACT Van der Heijden’s ENDGAME STUDY DATABASE IV, HHDBIV, is the definitive collection of 76,132 chess studies. The zugzwang position or zug, one in which the side to move would prefer not to, is a frequent theme in the literature of chess studies. In this third data-mining of HHDBIV, we report on the occurrence of sub-7-man zugs there as discovered by the use of CQL and Nalimov endgame tables (EGTs). We also mine those Zugzwang Studies in which a zug more significantly appears in both its White-to-move (wtm) and Black-to-move (btm) forms. We provide some illustrative and extreme examples of zugzwangs in studies. -
11 Triple Loyd
TTHHEE PPUUZZZZLLIINNGG SSIIDDEE OOFF CCHHEESSSS Jeff Coakley TRIPLE LOYDS: BLACK PIECES number 11 September 22, 2012 The “triple loyd” is a puzzle that appears every few weeks on The Puzzling Side of Chess. It is named after Sam Loyd, the American chess composer who published the prototype in 1866. In this column, we feature positions that include black pieces. A triple loyd is three puzzles in one. In each part, your task is to place the black king on the board.to achieve a certain goal.

Black is in stalemate. C. White has a mate in 1. For triple loyds 1-6 and additional information on Sam Loyd, see columns 1 and 5 in the archives. As you probably noticed from the first puzzle, finding the stalemate (part B) can be easy if Black has any mobile pieces. The black king must be placed to take away their moves.

Шахматных Задач Chess Exercises Schachaufgaben
Всеволод Костров Vsevolod Kostrov Борис Белявский Boris Beliavsky 2000 Шахматных задач Chess exercises Schachaufgaben РЕШЕБНИК TACTICAL CHESS.. EXERCISES SCHACHUBUNGSBUCH Шахматные комбинации Chess combinations Kombinationen Часть 1-2 разряд Part 1700-2000 Elo 3 Teil 1-2 Klasse Русский шахматный дом/Russian Chess House Москва, 2013 В первых двух книжках этой серии мы вооружили вас мощными приёмами для успешного ведения шахматной борьбы. В вашем арсенале появились двойной удар, связка, завлечение и отвлечение. Новый «Решебник» обогатит вас более изысканным тактическим оружием. Не всегда до короля можно добраться, используя грубую силу. Попробуйте обхитрить партнёра с помощью плаща и кинжала. Маскируйтесь, как разведчик, и ведите себя, как опытный дипломат. Попробуйте найти слабое место в лагере противника и в нужный момент уничтожьте защиту и нанесите тонкий кинжальный удар. Кстати, чужие фигуры могут стать союзниками. Умелыми манёврами привлеките фигуры противника к их королю, пускай они его заблокируют так, чтобы ему, бедному, было не вздохнуть, и в этот момент нанесите решающий удар. Неприятно, когда все фигуры вашего противника взаимодействуют между собой. Может, стоить вбить клин в их порядки – перекрыть их прочной шахматной дверью. А так ли страшна атака противника на ваши укрепления? Стоит ли уходить в глухую оборону? Всегда ищите контрудар. Тонкий промежуточный укол изменит ход борьбы. Не сгрудились ли ваши фигуры на небольшом пространстве, не мешают ли они друг другу добраться до короля противника? Решите, кому всё же идти на штурм королевской крепости, и освободите пространство фигуре для атаки. Короля всегда надо защищать в первую очередь. Используйте это обстоятельство и совершите открытое нападение на него и другие фигуры. И тогда жернова вашей «мельницы» перемелют всё вражеское войско. -
1 Domination and the Five Queens Problem
Ordog, SWiM Graph Theory Project: Domination and The Five Queens Problem 1 Domination and The Five Queens Problem What is the smallest number of queens that we can place on a chessboard so that every space on the board is either occupied by a queen or being attacked by at least one queen? How can you use graph theory to find a suitable arrangement of queens on an n × n chessboard? To find a solution to this problem, you will learn about the dominating set of a graph. 1.1 Domination • A dominating set of a graph G is a set of vertices S such that each vertex of G is either in S or adjacent to a vertex in S. • What is the biggest dominating set of the graph below? • What is the biggest dominating set for any graph G? • Can you find a dominating set with three vertices? Two vertices? One? Give an example, or explain why not. 1.2 The domination number • The dominating number of a graph, denoted γ(G), is the smallest number of vertices in any dominating set of a graph G. • What is γ(G) for the above graph? Page 1 Ordog, SWiM Graph Theory Project: Domination and The Five Queens Problem • Recall that the complete graph on n vertices, Kn, is the graph with n vertices such that each vertex is adjacent to every other vertex (they are all connected by an edge). What is γ(Kn)? • Exercise: Find γ(G) for the following graphs ([Smi88]). Look for and discuss patterns that might help come up with algorithms for finding dominating sets. -

The Vast Majority of Practical Games Do Not Involve Stunning Visual Tactics and Combinations and Are Instead More Mundane Affairs

If you are prone to moving too quickly then it will help you slow your play down and if you have a record of it then you can play over it later in order to either enjoy a nice game that you may have had or else figure out where you went wrong! We all learn from our mistakes and if you have a correctly completed score sheet then you can show it to someone else who may be able to offer you help. In competitions you will write down your game on specially-provided score sheets whilst some may obtain a scorebook so that they can all be written in the same place.
