In short: practise various forms of the shot with a fixed defender.
Organisation: teams of four per basket, one fixed forward and one fixed defender, the other two take turns shooting. After about 1 minute, the players change functions.
All forms of the shot mentioned with the exercises with threes are eligible to be practised in this form of organisation. The purpose of these exercises with the defender present can be to have the shooter perform the exercises at full speed (e.g. when shooting through balls or just the distance shot): not give the opportunity to "aim"), to bring the shooter more in the "game situation" (shooting with a defender right in front of you is very different than calmly laying down for a distance shot), to give the shooter a feeling of the right moment (making an evasive move which is followed by a breakthrough instead of a distance shot is not difficult, it is mainly about the moment that the defender is in the wrong position and the final move must be made), to start away in all directions. Note: the required turn is not the same in all cases, a turn can even be omitted when starting away in the extension of the post. The shot is most difficult when the archer walks straight towards the declarer; in other cases the shooting is easier, but the pure marking more difficult.
Exercise o. is an example of a combination of two standard movements. There are more to come, for example: starting away from the basket, but after receiving the ball take a walk-through ball, or: dodge over right, receive ball, play ball inside again and continue with a dodge ball over left, etc.
Point well!
The exercises a., b. and c. are especially meant to be able to shoot a ball that is not well placed.
To teach at which place a movement should be started (e.g. at a break-through that is broken off very suddenly and is then followed by a shot from very close range or at which place a dodge movement should be started).
Most korfball players do not like shooting drills with defenders present. However, for the reasons mentioned above, I think that shooting under pressure should be done regularly. It is essential that the defenders know what their function in this exercise is: it is about ......(filling in one of the goals mentioned above) and not about making it impossible for the shooter to shoot. It is a breeze for a defender to prevent any shot: he knows what is coming. On the other hand, if an attacker does not do well, the defender should indeed try to block the shot, or not fall into the poorly executed feint.
Course of the exercises:
(using the example of taking evasive balls). The regular attacker stands under the basket with the ball, the two shooters stand about 10 meters in front of the basket, the defender stands near one of them. The attacker with the defender is running towards the basket, forces the defender to run with him, makes a sudden evasive manoeuvre, freeing him from the defender, receives the ball and shoots. The defender tries to obstruct, but is just too late to execute properly. Immediately afterwards, the defender passes to the second attacker, who does the same, etc. After about 1 minute or after, say, five shots both shooters switch functions.
Variation: the two archers stand about 6 metres in front of the basket and about 4 metres from each other. The attacker stands under the basket. The defender must now defend both archers. The attackers may play together a maximum of two times, then one of them must shoot.
