Finally, another worthy Post.
I absolutely agree with you kingvaillant.
''SPORTSMANSHIP'' is something that should also be seen as some kind of a rule to follow, because it is in the first thing what causes the real rules to be broken by a player accidentally or not.
There is no rule that is perfect, any rule can be abused by a player for his/her own advantage and ''sportsmanship'' is something that fills this ''hole''.
