These videos shows an example of both players fast expanding, ultimately the Zerg player overwhelms the Protoss cannon wall.


Here is a good game between MoonGalde and Azz playing as Zerg and Protoss commentated by Hunter.

Both players go for a fast expansion. The Protoss does a nice job of walling off the choke point in front of his expansion with a Gateway, Pylons, a Forge and some Photon Cannons. Both do some small attacks on each other until the Zerg gets a strong group of speed Zerglings and Hydralisks to attack the Protoss wall.

He breaks through the wall but is eventually stopped. The Zerg then rebuilds his forces and takes another expansion while the Protoss masses Sentries, Zealots, and High Templar to Storm the Zerg forces. There are some epic battles in the second part that you have to see.
