Soccer (Football) Offside

"Offside (sometimes known as offsides) is a law in association football which states that if a player is in an offside position when the ball is touched or played by a team-mate, the player may not become actively involved in the play. A player is in an offside position when closer to the opponent's goal line than both the ball and the second-to-last defender (which is usually the last outfield player), and also in the opponent's half of the pitch. "Offside position" is a matter of fact, whereas committing an "offside offence" occurs when a player is "actively involved" and is subject to the interpretation of the referee. Goals scored after committing an offside offence are nullified if caught by the referee." [Offside (association football). Wikipedia]

"Offensive tactics in set pieces. ...
Throw-ins[edit]
How throw-ins are best handled depends on where it is:
(1) In one's own half the aim of a throw-in may be to retain possession in order to build up the next attack. The throw may or may not go toward the opponents' goal; the most unmarked player may be a full-back who is behind the ball. Such a throw followed by a quickly taken 'switch' pass can be an effective tactic. Under pressure however, the ball is often thrown up the line, toward the opponents' goal line to gain as much ground as possible.
(2) If the thrower is unmarked, a simple tactic is to take a short throw to the feet or chest of a marked player who immediately returns the ball to the thrower.
(3) In the last third of the pitch a player with a long throw can put pressure onto the defenders by throwing the ball deep into the opponents' penalty area, resulting in somewhat similar tactics to a corner kick situation, but with the added advantage of avoiding the offside trap, as an attacking player cannot be offside from a throw in. ...
Goal kicks.
A goal kick is an important 'set piece' that will occur many times in a game and yet few teams practice it. If taken quickly the kick may be taken short to a full-back who has run into a wide position. Although this may gain little ground it retains the all-important possession of the ball. A longer kick to the midfield is more common and it is vital that the midfield unit are in a position to receive it.
Corners.
A corner kick (or "corner") is a real goal scoring opportunity and it is essential to know who is the best at taking a good corner from both the left and right side of the pitch. A good corner will be aimed high across the goal and may be 'bent' towards or away from the goal. At least one of the forwards should be on or close to the goal line when the kick is taken.
Another tactic on a corner is to let the best shooter stay in the back "trash" position and have the defence worried about those up front. The player taking the corner kick makes a small pass back to the trash shooter who has time and space to take a good shot." [Association football tactics and skills. Wikipedia]

"In association football, the formation describes how the players in a team are positioned on the pitch. Different formations can be used depending on whether a team wishes to play more attacking or defensive football. ...
The WM system was created in the mid-1920s by Herbert Chapman of Arsenal to counter a change in the offside law in 1925. The change had reduced the number of opposition players that attackers needed between themselves and the goal-line from three to two. This led to the introduction of a centre-back to stop the opposing centre-forward, and tried to balance defensive and offensive playing. The formation became so successful that by the late-1930s most English clubs had adopted the WM. Retrospectively, the WM has either been described as a 3–2–5 or as a 3–4–3, or more precisely a 3–2–2–3 reflecting the letters which symbolised it. The gap in the centre of the formation between the two wing halves and the two inside forwards allowed Arsenal to counter-attack effectively. The W-M was subsequently adapted by several English sides, but none could apply it in quite the same way Chapman had. This was mainly due to the comparative rarity of Alex James in the English game. He was one of the earliest playmakers in the history of the game, and the hub around which Chapman's Arsenal revolved." [Formation (association football). Wikipedia]

"Gameplay.
Association football is played in accordance with a set of rules known as the Laws of the Game. The game is played using a spherical ball (of 71 cm (28 in) circumference in FIFA play), known as the football (or soccer ball). Two teams of eleven players each compete to get the ball into the other team's goal (between the posts and under the bar), thereby scoring a goal. The team that has scored more goals at the end of the game is the winner; if both teams have scored an equal number of goals then the game is a draw. Each team is led by a captain who has only one official responsibility as mandated by the Laws of the Game: to be involved in the coin toss prior to kick-off or penalty kicks.
The primary law is that players other than goalkeepers may not deliberately handle the ball with their hands or arms during play, though they do use their hands during a throw-in restart. Although players usually use their feet to move the ball around, they may use any part of their body (notably, "heading" with the forehead) other than their hands or arms. Within normal play, all players are free to play the ball in any direction and move throughout the pitch, though the ball cannot be received in an offside position." [Association football. Wikipedia]
