[robocup-small] RoboCup 2019: Rule Changes (June 2019)

[Christian Lobmeier]

Hi teams,

just to make sure that everyone is aware: the new "Attacker Touches Robot
In Opponent Defense Area" rule has some effects on the strategies that
might not be obvious. Placing an attacking robot close to the opponent
defense area is not a good idea any more since if the opponent defender is
partially inside its own defense area and touches the attacker, it counts
as a foul for the attacking team.

Best,
Christian
