Honestly i dont think so rabbit is a real gosu, it looks like and adverage between korean and normal player
he has high highs, but does tends to cut corners a lot. Tries too hard to shave off some minerals spent here and there to get advantages. When it pays off he has amazing games. When it fails he looks bad.
Vs rillo he had the weakest mid build because he wanted to save minerals. Had he gotten a little bit more time he would've had huge mass and held easily. Had he spent more on cannons to contain he would've been fine too. J.H and GoldSCV play a bit safer in that regard. Also, reaver shuttle micro is impossible on TR 8 Extra high. Which is only thing I can see him wanting to have relied on with only 2 cannons and 2 reavers to contain.
