Hehe, nice work bobo. Looking back on it I actually think I played really bad lol :(
Definitely could've (should've!) had a starport going down as I was moving out. The main reason I liked this build is because the CC stays in your base for a fair while. Because of it, most zergs usually presume you're going some kind of all-in our banshee because the game is 'quiet' for a little too long so they get uncomfortable and start making spores or something (like this zerg did). So this is a really good way to secure a relatively early expansion in my opinion, which is why I like it.
