Game 1, ZvZ: Oh good, my favorite matchup from last night. I tried the following build from www.allthingszerg.com:
17 Spawning Pool
19 Overlord (Stop Droning)
2x Zerglings (Scout)
@50 Gas Baneling Nest
Things went surprisingly well! He mis-controlled the mass of lings that he had early in the game, so I was able to expand behind it and get farther ahead. Mutas ruled the day. My mineral income got a little bit out of hand which tells me that I need to take a 3rd base for gas way earlier than I did.
Game 2, ZvP: Macro win! I took my 3rd early enough to basically have a 2:1 mineral to gas ratio so that my hydra production would be smooth. I won a big fight with him at around the 12 minute mark and from there it was just cleaning up the rest of his mess. I'm figuring out that if I leave each base on 11-12 drones by the time I'm getting my 3rd, the saturation for all of my bases becomes way more even and thus my economy is better off in the long term.
Game 3, ZvP: My first game from above my division (he was Plat, I'm still Gold, not that it means that much but it makes me feel good). Tense win. I'm honestly not sure how it happened - I got comfortable, thought he was going to roll over me, and just kept counterattacking when he'd try to move out. Eventually I'd done it enough that he had nothing left. Macro was good, not great - especially my mineral economy was out of control towards the end. I did learn that you can queue injects though, so now when I miss an inject after the 10 minute mark, I can keep them going and a constant larva stream.
With that one, I'm calling it a night because I've still got the adrenaline rush from it. 3-0 tonight (my win/loss has gone up to 10-9 this week!); things seem to be looking up! Hopefully I can keep it going tomorrow.
