Okay, I've come to a realization that maybe Shikamaru IS a genius. (Wow, that took quite a while. *.*) I was thinking about the Shikamaru vs. Tayuya fight. So, Shikamaru was too much for NORMAL and CS Tayuya, ne? Shikamaru had no power-ups like Tayuya did, I think. And CS2 Tayuya was too much. So Tayuya cheated, and...yeah.
Scratch all those posts about why he isn't a genius.
