This is a question, not an accusation (if I should have posted this somewhere else, please tell me where).
Another player told me that the rules forbid making or maintaining truces if there are only 3 players left in a (non-team) game. Is that somewhere in the rules?
In my experience, when 3 players are left, it's common for the two weaker players to make a temporary truce with each other so they can both fight the strongest player, at least until the players are "equalized"...
