The example below is for the opening position, so no moves are shown in the heading. The first row provides the move numbers with subsequent rows representing different variations. Since the initial position is not always the opening position, these numbers will not always start at "1." White half-moves are shown above black half-moves.
This is a list of chess openings, organised by the Encyclopaedia of Chess Openings (ECO) code classification system.The chess openings are categorised into five broad areas ("A" through "E"), with each of those broken up into one hundred subcategories ("00" through "99").
The openings are provided in an ECO table that concisely presents the opening lines considered most critical by the editors. ECO covers the openings in more detail than rival single volume publications such as Modern Chess Openings and Nunn's Chess Openings, but in less detail than specialized opening books.
Opening book is often used to describe the database of chess openings given to computer chess programs (and related games, such as computer shogi). Such programs are quite significantly enhanced through the provision of an electronic version of an opening book. This eliminates the need for the program to calculate the best lines during ...
Manuals giving general opening advice and guidance - Possibly the most famous example of this type of manual (in English) is Reuben Fine's The Ideas Behind the Chess Openings. This type of book does not analyze any opening system to much depth, but teaches the ideas that will help its reader understand opening play.
Since 1980, there have been other one-volume opening encyclopedias to rival MCO: Batsford Chess Openings (BCO) in 1982 and 1989, and Nunn's Chess Openings (NCO) in 1999. John Watson wrote that MCO-13 "really isn't up to modern expectations", [ 3 ] but called MCO-14 "a vast improvement over its predecessor No. 13 in almost every respect" and ...
When the size of the plastic zone at the crack tip is too large, elastic-plastic fracture mechanics can be used with parameters such as the J-integral or the crack tip opening displacement. The characterising parameter describes the state of the crack tip which can then be related to experimental conditions to ensure similitude. Crack growth ...
Crack tip opening displacement (CTOD) or is the distance between the opposite faces of a crack tip at the 90° intercept position. The position behind the crack tip at which the distance is measured is arbitrary but commonly used is the point where two 45° lines, starting at the crack tip, intersect the crack faces. [ 1 ]
