After the Silver exchange in the 5th file , MURANAKA sacrificed the 2nd file Pawn with 27.P-2d , and dropped a Pawn with 28.P*5d aiming at a Pawn promotion with P-5c+ . GOUDA swung his Rook with 28...R...5b to prevent this line .

MURANAKA pushed the 4th file Pawn with 29.P-4d to continue attacking , and GOUDA moved up the 5a-Gold with 29...G5a-4b to defend . Instead of 29...G5a-4b , the lines 29...Px4d , 30.S*5c , or 29...Rx5d , 30.S*4e seemed danger for GOUDA .

MURANAKA dropped a Silver with 30.S*5c and after the Silver and the 4b-Gold exchange , he swung the Rook with 32.R-4h to attack this line . Replying MURANAKA's 33.Rx4d , GOUDA dropped a Silver with 33...S*5h to attack MURANAKA's Kakoi .

After some moves , GOUDA dropped a Gold with 40...G*4e forking the 3f-Rook and the 5e-Silver . While GOUDA captured the 3f-Rook , MURANAKA made a promoted Pawn and dropped a Pawn with 42.P*5b driving away the 5a-Rook . GOUDA dropped a Rook with 43...R*6i and continued attacking .
