Off side, also know as forward position or offside, is the name by which a person is known rule that is applied in the soccer. The offside penalizes a player who, within the framework of an offensive situation, is in a position considered as illicit.
It is difficult to explain how this rule works, since it is linked to various specific and dynamic circumstances of the play. At a general level, it can be said that an attacker is offside when he only has the rival goalkeeper ahead facing the opponent’s goal and the ball is behind your position. In case the player is behind the midfield line, he will be automatically enabled.
If a teammate passes the ball to him and the attacker, when breaking the pass, barely has the rival goalkeeper as a stumbling block, he will be offside, which invalidates the play. Said violation of the regulation is indicated by the assistant referee or line judge, who will raise the flag to warn the head referee about the forward position. Once the offense is sanctioned, the team that was defending until then has a free shot in his favor.
It is important to note that the offside player will only commit an offense when try to play the game or gain an advantage from your forward position. This means that if a striker is offside but his teammates do not pass the ball to him, he will not have committed a regulation foul.
The purpose of the offside is to prevent a striker from remaining the entire match stationed next to the rival arch. Over the years, however, the sanction criteria were modified until they reached their current form.
To enforce this rule, the referee relies heavily on his assistant referee, who is usually located in a position parallel to that of the penultimate defender on the side of the field to which it has been assigned. The assistant referee has a difficult task, as he must pay special attention to attacks and counterattacks, assess who is offside each time the ball is played (even if they are at the opposite end of the court) and decide if said play involves to players who are offside.
Undoubtedly, offside arbitration carries a significant risk error, which is amplified by the effect of perspective, which occurs when the assistant referee is not in line with the defending player and his distance from him is very different from that between him and the attacking player. Added to this is the speed that professional players can achieve in a few seconds, which can significantly alter their position in a very short time. In general, the public does not appreciate such difficulty in detecting the offside.
Although offside is a punishable situation that occurs due to error of the attacking player, it can also be used as a defensive tactic. Also known as dewatering of spaces, the offside tactic is for defenders to move forward in a synchronized manner when an attacker is about to receive a pass, so that the pass is positioned behind them when receiving the ball, which automatically becomes a violation.
Very commonly, defenders who employ the offside tactic seek to call the attention of the assistant referee with signs or shouts when they are about to execute their plan, so that the offside can be properly detected. Among soccer fans there is the idea that the use of this deceptive tactic makes this sport boring and predictable, although this does not mean that it is a risky decision, which can fail and give a advantage considerable to attackers.
