Well, I went through a few of your games.
gameID=152265 - you went and stabbed Greece even though it was blatantly obvious that Carthage was coming at you. Greece had wanted peace.
gameID=153205 - Not going to go too in depth, but Pac-Rus probably had you as a target from the beginning. With that opening, why oh why did you contest Thailand. That made India an enemy.
gameID=152387 - you saw the English stab coming from the 1903 builds....yet did nothing about it. At that point you should've broke off right away with Italy and hit England with everything. You probably could've saved Germany's fleet.
gameID=151115 - That's just your fault.
Let me know if you want more :D
