I've still yet to play any of the campaign smh. I just got a bunch of new 360 stuff, so all my single-player time has been devoted to that. I'll check it out this weekend, though.
Playing Optimo is depressing 
I went in thinking "fuck it I'm going to lose, might as well try something else." So I used Idra's 14pool15hatch build, which I've actually been using a lot lately. It's dangerous and I haven't perfected it yet lol. Needless to say I got swamped in tanks soon enough
Ha I was trying rax -> factory -> rax instead of rax -> factory -> starport. I think it's less flimsy. I'll probably be sticking with it as a standard opening in TvZ.
I dunno what Idra's opening entails these days, but I'm assuming he gets ling speed? That tends to fuck up my early rine/hellion harass pretty well, and I don't think any sort of of single-base play from Zerg is viable against Terran mech unless you're going for like an early baneling bust or fast muta, so keep playing around with that build unless you're really uncomfortable with it.
I won my second game. The other dude had one Void Ray and two Zealots when I charged his base.

Speaking of which: PD, I still want revenge on your brother for that ugly, embarrassing loss
