   19.Px6e Nx6e 20.S6f P'6d 21.S4f P8f 22.Px8f Rx8f 23.P'8g R8a
   24.B2f P1d 25.P1f P9d 26.P9f (adjourned) 26... P2d 27.K7i G2c
   28.B5i K3b 29.B6h B3c 30.K8h B5a 31.P3e Px3e 32.Sx3e Sx3e
   33.Bx3e P'8f
After 33... P'3d 36.B6h B3c 35.P5e P7e 36.P'2e Px2e 37.N3g  black
stands slightly better, Y. Sato - Murayama 1-0, 1990.
   34.Px8f P'8e 35.R3h
35.Px8e?? Rx8e 36.P'8f N7g+ followed by 37... Rx3e and white wins.
   35... B3c 36.Px8e S'2g 37.R3g S2h= 38.R3f Sx1i+ 39.B6h +Sx2i
   40.P'2e N'5g! 41.S'3e?!
After 40.N'5g the position is unclear, although black still has a
slight edge. 41.S'3e is inaccurate, however, and should have been
41.P5e.
   41... N6i+ 42.B8f L'8c 43.Px2d G2b 44.N9g P9e 45.Px9e P7e
   46.S3d Bx2d 47.P'2c?!
42.R2f P'2d 43.Rx2i is better.
   47... G3c 48.P2b+ K2b 49.Sx3c Bx3c 50.P'2d P'9f 51.G'2c?
I think 51.R2f Bx2d 52.Rx2d P'2c 53.Rx2i is better than what happened
in the game.
   51... K3a 52.Gx3c Px9g+ 53.Lx9g
According to "Shukan Shogi" and the TV program "Go & Shogi weekly"
Habu's 53.Lx9g was the losing move. Habu should have played 53.Kx9g
followed by 53... Nx3c 54.Rx3c+ P'3b 55.N'2c K4a 56.+R2b with chances
for both players.
   53... Nx3c 54.P2c+ P'3b 55.B'2d G4b! 56.+Px3b 57.P'3d P'3e
   58.Rx3e S'4d 59.Px3c+ Sx3c 60.Bx3c+ Gx3c 61.P'3d G2c 62.P'2d P'8g
   63.Kx8g Lx8e 64.Px2c+ K4a 65.Sx7e Lx8f 66.Sx8f Rx8f 67.Kx8f N'7d
   68.resigns. Time used, black: 7:38, white 7:35.
