StarCraft II - The Art of Expanding
Time and time again, people trip up when it comes to expanding. Whether it be too early, too late, or when a massive force is waiting to welcome their worker, expansions determine the outcome to the game. Getting that income edge is one way to victory in StarCraft II, and this guide was built from scratch to help you expand at the right time and in the right place!
Try starting your expansion as you move out for an attack. These things take almost two minutes, and in those two minutes if you're unable to achieve victory, you can at return to a completed expansion and increase your income to come back twice as hard. What's more, your opponent certainly isn't worried about your Nexus being built, he's worried about the horde of Zealots and Sentries heading his way. Diversionary tactics often lead to the best expansion opportunities, especially at sneaky locations.
