Go ranks and ratings

Skill in the traditional board game Go is measured by a number of different national, regional and online ranking and rating systems. Traditionally, go rankings have been measured using a system of dan and kyu ranks. Especially in amateur play, these ranks facilitate the handicapping system, with a difference of one rank roughly corresponding to one free move at the beginning of the game. With the ready availability of calculators and computers, rating systems have been introduced. In such systems, a rating is rigorously calculated on the basis of game results.

Kyu and dan ranks

Traditionally, the level of players has been defined using kyu and dan ranks. Kyu ranks are considered student ranks. Dan ranks are considered master ranks. Beginners who have just learned the rules of the game are usually around 30th kyu. As they progress, they advance numerically downwards through the kyu grades. The best kyu grade attainable is therefore 1st kyu. If players progress beyond 1st kyu, they will receive the rank of 1st dan, and from thereon will move numerically upwards through the dan ranks. In martial arts which adopted kyu and dan rank system from Go, 1st dan is the equivalent of a black belt. The very best players may achieve a professional dan rank.

WWE 2K

WWE 2K is a series of professional wrestling video games currently developed by Visual Concepts and Yuke's and published by 2K Sports. The games in the series are based on the professional wrestling promotion WWE and feature professional wrestling match types, storylines, and playable characters based on WWE programming.

The series was originally named SmackDown! after WWE's SmackDown television program. The first release in the series was WWF SmackDown! in March 2000, which, along with subsequent titles, remained exclusive to Sony's PlayStation consoles. After the brand extension, the series was retitled SmackDown vs. Raw in 2004 to indicate the Raw brand was also featured. Within a few years, the series had expanded to a yearly release cycle for various seventh-generation consoles as well as mobile devices. Yuke's had also released the games in Japan under the name Exciting Pro Wrestling. However, after SmackDown! vs. Raw 2006, THQ took over as the Japanese publisher and the Japanese releases adopted the western name. The series was later renamed simply WWE for its 2012 and 2013 iterations.

Air force

An air force, also known in some countries as an air army, is in the broadest sense, the national military organization that primarily conducts aerial warfare. More specifically, it is the branch of a nation's armed services that is responsible for aerial warfare as distinct from an army, navy, or a marine corps. Typically, air forces are responsible for gaining control of the air, carrying out strategic and tactical bombing missions, and providing support to land and naval forces.

The term "air force" may also refer to a tactical air force or numbered air force, which is an operational formation either within a national air force or comprising several air components from allied nations. Air forces typically consist of a combination of fighters, bombers, helicopters, transport planes and other aircraft.

Many air forces are also responsible for operations of the military space, intercontinental ballistic missiles (ICBM), and communications equipment. Some air forces may command and control other air defence assets such as anti-aircraft artillery, surface-to-air missiles, or anti-ballistic missile warning networks and defensive systems. Some nations, principally Russia, the former Soviet Union and countries who modelled their militaries along Soviet lines, have an air defence force which is organizationally separate from their air force.

WWE

World Wrestling Entertainment, Inc. (d/b/a WWE) is an American publicly traded, privately controlled entertainment company that deals primarily in professional wrestling, with major revenue sources also coming from film, music, product licensing and direct product sales. WWE also refers to the professional wrestling promotion itself, founded by Jess McMahon and Toots Mondt in 1952 as Capitol Wrestling Corporation. As of 2014, it is the largest wrestling promotion in the world, holding over 300 events a year, and broadcasting to about 36 million viewers in more than 150 countries. The company's headquarters are located in Stamford, Connecticut, with offices in major cities across the world.

As in other professional wrestling promotions, WWE shows are not legitimate contests, but purely entertainment-based, featuring storyline-driven, scripted, and choreographed matches, though they often include moves that can put performers at risk of injury if not performed correctly. This was first publicly acknowledged by WWE's owner Vince McMahon in 1989 to avoid taxes from athletic commissions. Since the 1980s, WWE publicly branded their product as sports entertainment, which is considered to acknowledge the product's roots in competitive sport and dramatic theater.
