I've been trying to play Starcraft a bit more. I'm still a bit stuck on the Hard AI in 1v1 matches. TvT is brutal, honestly. I failed to expand and ultimately lost because of a lack of resources. I did alright with harassing but it was hard to manage and I wasn't very aware in terms of what I could or should do with my units. I frequently had my defensive ground units melt with each attack and my vikings and banshees were easily shot down, even with 3-3 upgrades. I think I should try to be more aware of my economy and what units I need to best fend off the enemy's units. If I get caught off-guard, I need to learn to produce units that counter the enemy's.
