1.P-7f P-3d
2.P-2f G-3b
3.P-2e Bx8h+
4.Sx8h S-2b
5.S-3h S-3c
6.P-3f S-6b
7.S-3g P-6d
8.S-4f S-6c

TANIGAWA choiced "Ittezon Kakukawari" as the opening of this game , and SATO selected "Hayakuri Gin" .

In this game , SATO pushed P-2e without G-7h . Why he select 3.P-2e ? Perhaps he wanted to try a move in this game . What is the move ?

33.P*7f G-5c
34.Sx8f B-6c
35.P-8g K-2b
36.K-8h N-7c

SATO prepared "Hayakuri Gin" attacking ; S-4f , and TANIGAWA replied with "Koshikake Gin" formation ; S-5d . After King's move , SATO started attacking .

(SATO must move K-6h or P-1f , before attacking . Please see my blog ;Yamajunn's Shogi Opening traps)

After 3rd file Pawn exchange , replying TANIGAWA's P-8e , SATO defended the left side of his camp once before further attacking ; K-7i . In this game , SATO perhaps wanted to try this move ; K-7i . Instead of this move , G-7h is more natural , but in the line after G-7h , Sente will get worse position . (see my blog ; Yamajunn' Shogi Opening traps)

By K-7i , Sente can avoid a fork , after attacking with P-3e .

Both players advanced their own camps .

After 145 moves , until S*1e , SATO won this game .
