Moves by players are made using the tables present in the chess club.
|

Every game is isolated to a table, just as expected.
|
||||
This means that communication during a game only has to pass by the players
|
||||
of that particular game, and the coordinator, making sure that no cheating

takes place.

|

This isolation of the games plays an imporant part in many properties of
|
||||
the GGS, the isolation means that games can for example be transferred
|
||||
between different chess clubs, furthermore, if cheating takes place, corruption
|
||||
can only occur in the particular table where it was found, and can not
|
||||
spread.

Moving chess players from one location to another is one of the alterations
|
||||
made to the real world chess club system to make the system more appropriate
|
||||
for a software setting.
|
||||
Allowing games to be transferred is not a property usually desired in a
|
||||
real world chess club, where transferring players would mean moving the
|
||||
players from one building to another.
|
||||
In the software setting, moving players means moving the game processes
|
||||
from one system to another, perhaps to balance the system load.
|
||||
This transfer of players can occur transparently, without notifying the
|
||||
players.

|

In order to make this life cycle as efficient and useful as possible, the
|
||||
scalability, fault tolerant and generic traits are added to the GGS.
|
||||
These are not shown in the algorithm, as these traits are tools in making
|

the algorithm behave as efficient as possible, and are not the main focus

when studying the life cycle of a game.
