Hmm, this was fun
I think I would describe myself as erratic, aggressive and diplomatic in that order, and with erratic not being an active strategy as much as a RPG-whim way of erratic.
I'm also a bad winner, that is, I don't like winning much. I like the war/contest aspect of the game, but I tend to feel sorry for my enemies if I go to well. I have to actively tell myself that it is a game to the other player as well, when I aggressively attack them. To lessen my feelings of compassion I tend to RPG as much as I can. This might lead to erratic behaviour.
