Right, but Rule 184.108.40.206 states,
A player may place influence received in this way only in countries where his side already has influence (as of the end of the regular setup phase) and may not place influence exceeding 2 more than what is needed for control of the country.
I'm wondering if this was the rule used in the tournament, or if there was no limit to the amount of over-control.
Tourney rules override the rulebook. There has been much stranger rule(s) in tourneys.
