Attacking tactics is very hard to generalize since there are numerous ways to form an attack.
There is however some tips and tricks you may use generally in order to gain an advantage during the attack.

The basis for all attack is the defence. The better defence the more attacks.
It is also important that the whole team form an attack together. Single-handed attacks are easy to defend and rarely conclude in goals.

Starting an attack

When obtaining control of the ball, the attack must be formed quickly. The faster the attack is formed the more difficult it is for the opponent to defend. When starting an attack the first pass is critical. It is therefore very important that the player with the ball use the five seconds at hand to make sure that the first pass is safe.
On the other hand it is even more important that the players without the ball move around in order to generate free space for the first pass to be played safely.

An easy way to quickly generate this free space is to spread out on the field. The players without the ball move out to the sides while the player with the ball move into the centre of the field. This automatically generates a lot of passing opportunities [Figure 1]. If all players are still defended the next step is for them to switch sides.
The side switch automatically generates even more opportunities to make the first pass [Figure 2].
Switching sides also makes it difficult for the defenders due to the "screening" (see below).

Figure 1 also shows a special tactic called "the train". Players C and D follow each other along the sideline.
A first pass to player D is usually very safe since the defenders concentrate on the player closest to the opposite goal, namely player C. The path of player D is "protected" by player C making it difficult for a defender to get in between. When the first pass has been made, there are at least three different possibilities:

1. Player C changes direction, heading into the centre of the field.
   This gives player D the opportunity to either pass player C diagonally from behind or to continue along the side with the ball in order to make a later pass.
2. Player C continues along the sideline.
   This makes it possible for player D to make the next pass in the "corridor".
3. Player D moves into the centre of the court, taking the position of player A, who in turn continues straight for the opposite goal.
   This gives player D several passing opportunities similar to the ones shown in [Figure 2].

If none of the above tricks works the last way out is a pass back to the goalkeeper.
This restarts the whole scenario, meaning that all players need to move back towards the goalkeeper in order to form a new attack.

Give and go

The "give and go" is a quite simple move that can be useful in many situations. "Give and go" means passing a teammate, run towards the opponents' goal and get the return pass while in motion.

Many defenders have a tendency to keep their eyes on the ball at all times, which is a quite normal reaction. Thus, when the first pass is made they move their sight to the teammate receiving the ball. This leaves the player passing the ball unattended for a short while just enough for him/her to run past the defender and get ready for the return pass.
When the return pass is made the attacking team has a numeric advantage in players as well as speed.

"Screening"

An effective way of generating free space while playing against a unified defence is the use of screening.
This is done by having the player with the ball and one teammate switch sides by running towards each other.
During the switch the two defenders either collide or switch players to defend. Either way, during the switch the attackers generate a short moment of confusion, which in turn means an offensive advantage.

Screening is extremely effective against a slow and inexperienced defence.

The sample tactic described in the section "Starting an attack" above, includes "screening" when
players B and C switch sides [Figure 2].

Moving patterns

Another effective attacking tactic are the use of "moving patterns". This is the way the team is moving on the court in order to generate an efficient attack. A good offensive team has many "moving patterns" memorized making it easy to generate free space and making it difficult for the defenders to organize an effective defence.

Moving patterns are normally the last tactic skill a player learns. When teaching moving patterns it is important that all players know each other well. The use of these patterns must be improvised. It is up to the players to decide which pattern to use at each occasion respectively.

The greatest difficulty when using "moving patterns" is to choose the right pattern at the right time and get all the team mates to use the same pattern. This must be done on the fly during the game otherwise the attack usually fail "big time".

A simple moving pattern is the one described in the section "Starting an attack" above.
