Dear Shogi Fans,

Here is the problem #8. Following to #7, this problem
also deals with the technique called 'Ikken Ryu' in
the endgame.

Problem #8

Following to Problem 8, this position sometimes
appears in the game. Never let the promoted Rook
escape. Attack with the power of the promoted Rook.

This is also one of the lines for endgame.

The right answer line is N*3d Px3d  G*3c  K1c +Rx3b

Point : Make the vacant space at the sacrifice of kNight.

+R4a(Approx. 40 kyu). This move aims N*4d or G*2a
after escaping the promoted Rook, but not so good.

Make the vacant space with N*3d, Px3d, then brinkmate
comes with G*3c, K1c, +Rx3b. This is the same aim as Q7.
