Zerg v Protoss: Early 10 Roach Push

This build is an aggressive roach/zergling attack designed to destroy protoss opponents who go for the forge fast expand build. The attack hits early at around 7:20 before any major protoss tech has completed and if unscouted should do sufficient damage or win the game outright.

09 - Overlord
14 - Extractor
14 - Spawning pool
15 - Overlord
15 - Queen
17 - Zerglings x6
20 - Zergling speed

Remove Drones from gas, but then return them once the scouting Probe has left. 

It is critical from this point out to deny scouting information. Use your six zerglings to control Xel'Naga watchtowers, watch the entrance to the protoss' base and constantly scout for hidden probes and pylons.

20 - Hatchery
19 - Drone
20 - Overlord x2
20 - Roach warren (around 4:25)

Cancel the hatchery when Zergling Speed is completed (around 5:20)

20 - Roaches x10 (around 5:45)
40 - Overlord

Remove all drones from gas

40 - Continuously produce Zerglings from this point

This build is very dependent on denying all scouting information which your opponent possesses. If the cancelled hatchery or early roach warren are spotted the protoss has a chance to produce additional units and cannons which severely diminishes this builds chance of doing damage.
