The diagram 1 is a beginning of Yokofutori game . In Ai Yokofutori game , Gote captures the 7f-Pawn after the Bishop exchange like following line ; 8...Bx8h+ , 9.Sx8h Rx7f .
You may think "Why Gote player doesn't capture the 7f-Pawn without Bishop exchange with 8...Rx7f ?" . Because following moves gives Sente a nearly win advantage .
Replying Gote's 8...Rx7f , Sente simply exchanges the Bishops with 9.Bx2b+ . When Gote captures the 2b-promoted Bishop with 3b-Gold or 3a-Silver , the other piece will become unprotected .
Even if Gote drops a Pawn with 9...P*3c blocking the 3d-Rook's power , Gote will lose a Gold and a Silver and will have a bad position .
