High Quality Content by WIKIPEDIA articles A gambit (from ancient Italian gambetto, meaning tripping) is a chess opening in which a player, most often White, sacrifices material, usually a pawn, with the hope of achieving a resulting advantageous position. Some well-known examples are the King's Gambit (1.e4 e5 2.f4), Queen's Gambit (1.d4 d5 2.c4), and Evans Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4). A gambit used by Black may also be called a gambit (e.g., Latvian Gambit (1.e4 e5 2.Nf3 f5), Englund Gambit (1.d4 e5), but is sometimes called a "countergambit" (e.g., Albin Countergambit) (1.d4 d5 2.c4 e5) or Greco Counter-Gambit, an old-fashioned name for the Latvian Gambit). The word "gambit" was originally applied to chess openings in 1561 by Spanish priest Ruy Lopez de Segura, from an Italian expression dare il gambetto (to put a leg forward in order to trip someone). Lopez studied this maneuver, and so the Italian word gained the Spanish form gambito that led to French gambit, which has influenced the English spelling of the word. The broader sense of "opening move meant to gain advantage" was first recorded in English in 1855.

It is one of several forms of smart antenna technology. MIMO technology has attracted attention in wireless communications, because it offers significant increases in data throughput and link range without additional bandwidth or transmit power. It achieves this by higher spectral efficiency and link reliability or diversity. Because of these properties, MIMO is an important part of modern wireless communication standards such as IEEE 802.11n, 4G, 3GPP Long Term Evolution, WiMAX and HSPA+.

Development economics is a branch of economics which deals with economic aspects of the development process in low-income countries. Its focus is not only on methods of promoting economic growth and structural change but also on improving the potential for the mass of the population, for example, through health and education and workplace conditions, whether through public or private channels. Thus, development economics involves the creation of theories and methods that aid in the determination of types of policies and practices and can be implemented at either the domestic or international level. This may involve restructuring market incentives or using mathematical methods like inter-temporal optimization for project analysis, or it may involve a mixture of quantitative and qualitative methods. Unlike in many other fields of economics, approaches in development economics may incorporate social and political factors to devise particular plans. Different approaches may consider the factors that contribute to economic convergence or non-convergence across households, regions, and countries.

Dance is a sport and art form that generally refers to movement of the body, usually rhythmic and to music, used as a form of expression, social interaction or presented in a spiritual or performance setting. Dance may also to regarded as a form of nonverbal communication between humans, and is also performed by other animals (bee dance, patterns of behaviour such as a mating dance). Gymnastics, figure skating and synchronized swimming are sports dance disciplines, while martial arts kata are often compared to dances. Motion in inanimate objects may also be described as dances (the leaves danced in the wind), and certain musical forms or genres. Definitions of what constitutes dance are dependent on social, cultural, aesthetic, artistic and moral constraints and range from functional movement (such as folk dance) to virtuoso techniques such as ballet. Dance can be participatory, social or performed for an audience. It can also be ceremonial, competitive or erotic
