I really love this strategy. It's very map control oriented, and because of that, I'll frequently get several observers and put them around the map so that I always have a very clear idea where his army is, and when I can counter-attack.

Anyone figure out how to transition into this mid-game type of plan? I have trouble sort of stabilizing an opening of some sort to get to the point where I can just mass Stalkers.

Also, map-wise, I know that it doesn't work terribly well on Delta Quadrant because how narrow the map can be. It's great on Xelnaga and Metalopolis.
