(diagram 3) Afterdiagram 2 4.P-2d? Px2d 5.Rx2d Bx8h+ 6.Sx8h B*3c 7.R-2h P*2f 8.N-7g R-2b 9.S-3h (diagram 3) Sente tries to break Gote's Bishop head with 4.P-2d . After the Pawn exchange , Gote exchanges the Bishops and drops his Bishop with 6...B*3c . This Bishop dropping is forking 2d-Rook and 8h-Sivler . To proct both 2d-Rook and 8h-Silver , Sente's Rook backs to 2h . Gote drops a Pawn on 2f .If Sente captures this Pawn with 8.Rx2f , the8h-Silver is captured by Gote's 3c-Bishop for free . Sente's 8.N-7g blocks Gote's Bishop line . Gote's Rook comes to 2b . Sente should protect the 2nd file to decline Gote's Pawn promotion ; P-2g+ . So Sente moves up the right Sivler with 9.S-3h .
