25th Kio-sen, Game 4, 21 March 2000
Notes by Reijer Grimbergen

1. P7g-7f 2. P3c-3d 3. P2g-2f 4. P8c-8d 5. P2f-2e 6. P8d-8e 7. G6i-7h 8. G4a-3b 9. P2e-2d 10. P2cx2d 11. R2hx2d 12. P8e-8f 13. P8gx8f 14. R8bx8f 15. R2dx3d 16. B2b-3c 17. R3d-3f 18. S3a-2b 19. P*8g 20. R8f-8e

(A diagram) After three consecutive wins by black, Habu is looking to break the pattern and decide the match in game 4. It is not a big surprise that he selects the R8e Yokofudori for this. Moriuchi will have prepared this.

21. R3f-2f 22. K5a-4a 23. G4i-3h 24. S7a-6b 25. S3i-4h 26. P7c-7d 27. K5i-5h 28. G6a-5a 29. P3g-3f 30. P*2e 31. R2f-2h 32. P*8f 33. P8gx8f 34. R8ex8f 35. P4g-4f 36. R8fx7f 37. B8hx3c+ 38. N2ax3c 39. S4h-4g 40. P2e-2f 41. N8i-7g 42. N8a-7c 43. N2i-3g 44. B*4d!


Long thought but with good reason. The following complications are very hard to judge. White seems to be getting a strong attack, but it is unclear if it is strong enough or if white can defend and win from there. The preliminary conclusion is that B*4d is a good move.

45. P6g-6f 46. B4dx6f 47. K5h-6g

Puts the pressure on black's major pieces. Moving the king up towards the enemy pieces is quite frightening, though.

48. P7d-7e 49. S4g-5f 50. N7c-8e!

(A diagram) Strong attack. It seems like white has the advantage here, but Moriuchi will show that things are still very close.

51. S7i-6h 52. B6f-4d 53. P*7c!

Good move that shook Habu's confidence a little.

54. S6bx7c!

Looks dangerous, but it is white's strongest reply. 54.G6a or S7a would weaken white's position too much.

55. R2h-2i

Very tempting is 55.Nx8e, but after 56.Bx9i+ P*7g R8f white gets an overwhelming position after both Nx7c+ L*6f~R8a+ and P*8g L*6f~Rx8e. Having to give up the move to white is a tell-tale sign that white has the advantage.

56. R7f-6f 57. K6g-5h 58. N8ex7g+ 59. S6hx7g?!

(A diagram) Immediately after the game was over, Moriuchi suggested 59.Gx7g as better. It seems that black can stop the white attack after for example 60.R6d P*6f R8d P*8e R8b G4h P5d.

60. R6fx5f 61. P5gx5f 62. P7e-7f 63. P*6f 64. P7fx7g+ 65. G7hx7g 66. N*6e 67. G7g-6g 68. P2f-2g+ 69. R2ix2g 70. S*7h 71. P6fx6e 72. S*6i 73. K5h-5g 74. P*2f 75. R2g-2i 76. S7hx6g+ 77. K5gx6g 78. B4dx9i+ 79. K6g-5g 80. G*5h 81. K5g-4g 82. +B9i-6f 83. P3f-3e!


It seems like white is steamrolling through black's position, but this move is a strong fighting move. The black king can suddenly run away and it is not so easy to mate him with only a lance.

84.P*3d

Here, Habu was not sure of the position anymore. This move is not a mating threat, so black gets a chance to counterattack.

85. N*2d 86. G5h-5g 87. K4g-3f 88. P3dx3e 89. K3fx2f 90. L*2c 91. R*2a 92. K4a-5b 93. R2ix6i


Suddenly the roles are reversed. Moriuchi has a strong attack and Habu must defend.

94. L2cx2d 95. P*2e 96. N*3d 97. K2f-2g 98. +B6fx5f 99. P*5d

If black can find a way to make consecutive mating threats, he will win. However, it seems that white can barely survive. Black would like to play 99.N*6d here, but unfortunately for him he is mated after 100.Sx6d Px6d N*1e.

100. G3b-3a 101. P5dx5c+ 102. K5bx5c 103. B*7e

Without pieces in hand for intermediate drops, white seems to be in trouble here...

104. P6c-6d!


Great defence and the deciding move. 105.Px6d P*6h stops black's attack.

105. P*5d 106. K5c-4b 107. P5d-5c+ 108. K4bx5c 109. N*4e 110. N3cx4e 111. N3gx4e 112. K5c-6b 113. B7ex5g


Moriuchi realises he has lost and plays a "katachizukuri" move.

114. L2dx2e 115. P*2f 116. L2ex2f 117. K2g-1h 118. +B5fx5g 119. P6ex6d 120. B*3f 121. P*2g 122. L2fx2g+ 123. G3hx2g 124. B3fx2g+ 125. K1hx2g 126. P*2f 127. K2g-1f 128. N*2d


Moriuchi resigns
Time: 03:59:00 03:58:00

Mate after 129.K2e +B4g K3d G*4d K2d +B1d. Moriuchi again tried everything in this game, but Habu is almost invincible in the endgame. With this result, Habu ended the Kio match with a 3-1 result. This is the 10th Kio title in a row that he has won and he is only the second player in history to get 10 or more consecutive titles. The great Oyama Yashuharu did it twice with 13 consecutive Meijin titles and 12 consecutive Osho titles. Can Habu break these records?
