This is what we found on Wikipedia regarding the Abu Dhabi International Basketball Championship:

Basketball is a team sport in which two teams of five players each (excluding substitutes), opposing one another on a rectangular court, compete with the primary objective of shooting a basketball through a hoop (a basket mounted to a backboard) at each end of the court. Teams alternate between offense, when they attempt to score, and defense, when they try to prevent the opposing side from scoring. A field goal is worth two points, unless made from behind the three-point line, when it is worth three. After a foul, timed play stops and the fouled team either takes one to three free throws worth one point each, or restarts play with an inbound pass. The team with the most points at the end of the game wins. If regulation play expires with the score tied, most basketball leagues mandate additional periods of play (overtime) until the score is no longer tied.

Players advance the ball by bouncing it while walking or running (dribbling) or by passing it to a teammate, both of which require considerable skill. On offense, players may use a variety of shots – the layup, the jump shot, or a dunk; on defense, they may steal the ball from a dribbler, intercept passes, or block shots; either offense or defense may collect a rebound, that is, a missed shot that bounces from rim or backboard. It is a violation to lift or drag one's pivot foot without dribbling the ball, to carry it, or to hold the ball with both hands then resume dribbling.

The five players on each side fall into five playing positions. The tallest player is usually the center, the second-tallest and strongest is the power forward, a slightly shorter, but more agile player is the small forward, and the shortest players or the best ball handlers are the shooting guard and the point guard, who implement the coach's game plan by managing the execution of offensive and defensive plays (player positioning). Informally, players may play three-on-three, two-on-two, and one-on-one.

Invented in 1891 by Canadian-American gym teacher James Naismith in Springfield, Massachusetts, in the United States, basketball has evolved to become one of the world's most popular and widely viewed sports. The National Basketball Association (NBA) is the most significant professional basketball league in the world in terms of popularity, salaries, talent, and level of competition (drawing most of its talent from U.S. college basketball). Outside North America, the top clubs from national leagues qualify to continental championships such as the EuroLeague and the Basketball Champions League Americas. The FIBA Basketball World Cup and Men's Olympic Basketball Tournament are the major international events of the sport and attract top national teams from around the world. Each continent hosts regional competitions for national teams, like EuroBasket and FIBA AmeriCup.

The FIBA Women's Basketball World Cup and women's Olympic basketball tournament feature top national teams from continental championships. The main North American league is the WNBA (NCAA Women's Division I Basketball Championship is also popular), whereas the strongest European clubs participate in the EuroLeague Women.
