Conditions that made the win possible:
1) My opponent was playing an off-race.
2) My opponent opened with a BBS bunk rush against cross positions on Luna (11 vs 5 o'clock).
3) My opponent's marines passed under one of my scouting overlords, so when their SCV showed up I knew what it was going to do.
4) My opponent didn't focus fire my sunkens as they were morphing.
5) I was able to kill all of my opponent's early marines and forced them to pull SCVs to defend their base.
6) After a weak attempt at breaking their contain, my opponent overreacted and pull their containment force back to their natural to defend as they expod.
7) My opponent wasted 2 scans looking for my army just before I attacked with 7 lurkers and 2 groups of hydraling.
And that was gg.
A lot of factors had to align for me to win that game. It was a complete fluke, I know. Immediately a re was given, and of course I lost the next game.
I've played this person dozens of times; it warmed my insides to win once-- even if it was a fluke.
