I looked up this guy's last 8 PvT games. He never does the same build order twice. There is no discernible pattern, I'm not particularly convinced that this guy even uses build orders.
When I say standard I mean it looks like a general strategy other people commonly do. Not that the build order itself is standard or correct.
mobo means mothership core
warp means warp gate
bay means robotics bay
Pete vs Ivraa - nexus first into late oracle - standard

I have utterly no idea how to go about practicing for this guy. He doesn't have a build to practice against and only half of the time does he even seem to be doing something sensible. This should be interesting...
