wow you people have no imagination.....dont listen to these noobs. My strategy is to go as far right or left and hug the boundry lines and then work my way in once I am Perpendicular to their "line." Hopefully thier far flank isnt heavily occupied, but it truely is a numbers game. If you can build enough numbers on the boundry line and push up from that, you will be able to secure a really good flank and use the boundry to your back so you your self dont get flanked
