FUKAURA selected Kakugawari opening in this game and NAKAMURA accepted it . After exchanging the Bishops , NAKAMURA moved up the Silver with 5...S-3b making Hidari mino shape . (However , I can't find effective reply against 6.B*4e . )

While FUKAURA was making Koshikakegin form , NAKAMURA quickly let his King enter Hidari mino with 13...K-3a and started attacking with 15...P-7e .
