Now when that is solved, I'll have to ask: Which category would you use?
Turtling:
Hide in your first base, building extreme defenses and mass up an army. Take over a new one after all resources are gone and set up new mass defenses.
Expanding:
Quickly build units, have a mass of them and take over as many bases as quick as possible.
Rushing
Focus only on building units in the start of the game as quick as possible and as the name says, rush your enemies in hope of a quick defeat. If you lose your rush, you've usually lost the whole game, unless your Zerg.
Harassing
Constantly find holes in your enemies defense and destroy a few of their mineral workers of maybe a building of importance constantly and prevent the enemy to recover and progress.
