Notes:

• This build order is for getting early Observers to scout your opponent and then transitioning into a build for countering him.

• If your opponent is terran and massing marauders, it would be better to get immortals over colossus.

• If your opponent is going for units that counters Colossus, it would be wise to start producing them right away and continue to produce them. Use your observer!

• If your opponent expands early, it would be a good time to expand or do a timing attack if they lack defense.

• If your opponent builds a stargate, starport then you should produce one yourself to counter it.
