If White decides to play Sanken-Bisha , he (or she) should open
own Bishop's way by P-3d and reclose Bishop's way by P-4d , and
range Rook at 3b square . Usually White's left Silver is moved after
Rook ranged , because moved Silver closes the Rook's ranging way .


Black's move 4. P-2e means that Black avoid the White's Ishida-ryu .
Both players are going to castle their own King .
