the flag tool: It was created just to give us a tool to end game without the need of kill every one but the winner. Then, players start to use it like a diplomatic weapon and created a simple agreement between players during the game: the vflag. Flags are not part of the rules. There is no official position. Its just common sense agreement. Some of us think that flag to another player mean: I will not be in a position above you. I am one of them. Others think different: flag to another player mean: i will not hit you. And others use both concepts, attending their own interests. Choose yours. There is not only one truth.
