After pushing 9th file Pawns , SUGAI pushed 5th file Pawn with 3...P-5d , and he seemed to select Gokigen Nakabisha . But , he ranged his Rook with 4...R-3b making his original Sanken Bisha formation .

SUGAI exchanged his Rook with  5...Bx8h , and moved the Rook again with 7...R-2b , transposing  to Kakukoukan Furibisha . He made the mino gakoi with 11...S-7b  and pushed the Pawn with 13...P-8d to develop his kakoi to Ginkanmuri . But replying SUGAI's 13...P-8d , HABU dropped his Bishop with 15.B*6f to capture the 8d-Pawn . SUGAI sacrificed the Pawn  and aimed at HABU's Bishop .  HABU crashed the 5th file Pawn with 20.P-5f to make 8d-Bishop's way .

Forced to back HABU's Silver by 22...P*5e  ,  SUGAI developed  his Mino gakoi to Ginkanmuri , HABU also started developing his Kakoi to Ibisha Anaguma . But before completed it , HABU attacked the 3rd file with 28.P-3e .

SUGAI advanced his left Gold to defend the 3rd file . HABU closed the hatch of the Ibisha Anaguma with 32.S-8h to finish making it , and SUGAI advanced the 4th file Pawn to start attacking .
