Cheesy Builds

What do you guys think of cheesy builds. Some builds that are classified as cheesy builds (in my book) are:

Protoss:
2 Gate zealots. Very hard to defend against if you are a Protoss/Zerg player and you were not able to scout in time.

Fast Voidray: Hard to deal with if you are Zerg.

4 Gate: Not really a cheese Strategy, but very aggressive and Powerful.

Fast Dark templar: Not used often, but can be hell if encountered.


Zerg: 6 pool, 8 pool. I guess thats all the cheese Zerg has.

Terran:
Fast Reapers.
2 barracks marine rush proxy.
Fast Banshees.
Marauder marine rush. -semi cheese, but good strat as it is very aggressive.
Thor rush.
