What is the right keeper

position to defend a shot?

107

Depends on shot type

• Straight line

- advance on the meddle line or diagonal meddle line

• Parabolic

- stay on the meddle line near the meddle position

• Curve

- stay on the meddle line near the meddle position

108

How to predict a straight line,

a parabolic, or a curve shot?

109

Straight Line Shots

• Balls on the grass

- when the player is pressed- most common, because it requires less ability

- in case of doubt, it should be your choice

• Kicking balls

- when the foot does not make an up movement

110

Parabolic Shots

• Balls on the grass

- when the player is not pressed- it requires some ability

- knowledge about the player would help

• Kicking balls

- when foot makes an up movement

- the most common shot

111

Curve Shots

• Balls on the grass

- when the player is not pressed- requires a lot of ability

- knowledge about the player would help

• Kicking balls

- only in occasional shots

• Balls above defenders line

- left lateral movement

• Parabolic balls beside defenders line

- right lateral movement

• Straight line balls beside defenders line

- diagonal movement

127

Close

• Player in the unconditional close zone

- always make a close

• Player in the conditional close zone

- close just if there is a single adversary

- pay attention with kicking balls

128

Break

When ball is a bit far from the player make

a break instead of a close

Interruption: referee break.

After each interruption the score is updated,

output: score

System Dynamics

• Player is an autonomous system

• Team is a set of players

• Game: one team plays against other

• Team objective in a game: make goals and avoid adversary goals

205

System characterization

• Player ability: dictionary of actions and capability of executing it

• Player strategy: prediction of next events and planning of corresponding action sequences

206

System modeling

• Dictionary action: stochastic dynamical systems

(Markov chains) – discrete or hybrid

• Player strategy

- prediction: conditional distribution,

P(fact | system state)

- planning: mapping of a fact in a sequence of

dictionary actions
