TANIGAWA led the openig "Gokigen Nakabisha" . HABU seemed to select "Nimai Gin kyuusen" to beat "Gokigen Nakabisha" , because he advanced his camp without P-2e . Then TANIGAWA exchanged the Bishops and ranged the Rook to 2b , so opening became "SATO ryu Mukai Bisha" with Bx8h+ .



SATO uses several "Mukai Bisha" openings as Gote . I show some lines below as examples .

HABU tried to get the advantage by dropping his Bishop at 7g square , TANIGAWA had better to defend his Rook on 2b . TANIGAWA escaped his Rook to 1b , HABU tried attacking 2nd file , TANIGAWA protected there by G-3b . Against HABU's 2nd file Pawn exchange , TANIGAWA must use his left side pieces and several moves to protect 2nd file before he uses the Rook at 1b .

While TANIGAWA made his Rook useful , HABU advanced his camp . HABU succesfully made "Ginkanmuri " , but TANIGAWA cost too many moves and pieces on his left side he couldn't made safe castle without any defects . In other words , HABU got a better position .



After 123 moves until P'6f , HABU won this game .
