Tanigawa did everything right for most of the game=20 and seemed to be on his way to make it 2-2, but Habu managed to confuse=20 Tanigawa enough to turn the tables and win. Here is the game with comments:= [Black "Tanigawa Koji, Oi"] [White "Habu Yoshiharu, Challenger"] [Event "45th Oi-sen, Game 4"] [Date "August 25th and 26th 2004"] 1.P2g-2f 00:00:00 00:00:00 2.P3c-3d 00:00:00 00:04:00 3.P7g-7f 00:08:00 00:04:00 4.P4c-4d 00:08:00 00:08:00 5.P2f-2e 00:16:00 00:08:00 6.B2b-3c 00:16:00 00:09:00 7.S3i-4h 00:16:00 00:09:00 8.P9c-9d 00:16:00 00:18:00 9.G4i-5h 00:25:00 00:18:00 10.R8b-4b 00:25:00 00:40:00 After three games of Furibisha, commentators were expecting an Ibisha=20 game, but Habu again selects a ranging rook opening, this time the=20 Shikenbisha. 11.K5i-6h 00:29:00 00:40:00 12.S7a-7b 00:29:00 00:47:00 13.K6h-7h 00:31:00 00:47:00 14.S3a-3b 00:31:00 00:58:00 15.P5g-5f 00:38:00 00:58:00 16.P6c-6d 00:38:00 01:15:00 17.S4h-5g 00:53:00 01:15:00 18.G4a-5b 00:53:00 01:38:00 19.P3g-3f 02:02:00 01:38:00 20.K5a-6b 02:02:00 02:08:00 21.B8h-5e 02:29:00 02:08:00 22.S7b-6c 02:29:00 02:21:00 23.P3f-3e!? 03:04:00 02:21:00 In official tournament games this is a new move. There have been two=20 games played with this position (Moriuchi-Nozuki in the Kisei tournament= =20 and Ono-Iijima in the Asahi Open), but in both games black played 24.P6f= =20 next and the game became a slow build-up. 23.P3e is a positive attacking= =20 move, suited to Tanigawa's playing style, but not a move he thought=20 about himself. One of the reporters in the press room, Tanabe, had been=20 at a shogi festival in Nagano, where Tanigawa played an exhibition game=20 against Nozuki. In that game Nozuki played 23.P3e and even though in the= =20 end Tanigawa won that game, he must have been impressed enough with the=20 power of the black attack to try it himself at the big stage. Judging=20 from this game, 23.P3e is a very interesting move. Black can break=20 through on the second file and the awkward position of the white king=20 makes the white position hard to defend. 24.P3dx3e 03:04:00 03:07:00 25.S5g-4f 03:05:00 03:07:00 26.P4d-4e 03:05:00 03:08:00 27.B5ex3c+ 04:17:00 03:08:00 28.N2ax3c 04:17:00 03:08:00 29.S4fx3e 04:17:00 03:08:00 30.P*3d 04:17:00 03:12:00 31.P2e-2d 04:30:00 03:12:00 32.P2cx2d 04:30:00 03:16:00 33.S3ex2d 04:31:00 03:16:00 34.P4e-4f 04:31:00 03:24:00 35.S2dx3c+ 04:35:00 03:24:00 36.S3bx3c 04:35:00 03:24:00 37.P4gx4f 04:35:00 03:24:00 38.R4bx4f 04:35:00 04:11:00 39.R2h-2a+ 04:40:00 04:11:00 40.B*4d!? 04:40:00 04:50:00 Habu is aware that his position is worse and tries everything to confuse= =20 Tanigawa. The natural move is 40.B*5d, but after P*4c R4i+ G6i-5i +R3h=20 P*3i white has no good square for the promoted rook (+Rx3i fails to the=20 fork B*6f). Also, immediately 40.R4i+ is not good because of B*2g=20 followed by Bx6c+ and N*5e. 41.N*5e 04:51:00 04:50:00 42.S6c-7b 04:51:00 04:54:00 43.+R2ax1a 05:16:00 04:54:00 44.R4fx5f 05:16:00 05:07:00 45.L*5g 05:27:00 05:07:00 46.R5fx7f 05:27:00 05:44:00 47.P*7g 05:27:00 05:44:00 48.R7f-4f 05:27:00 05:44:00 49.+R1a-4a 06:29:00 05:44:00 50.B4dx5e 06:29:00 06:12:00 51.P*4e! 06:31:00 06:12:00 Habu completely overlooked this move. He thought that black could only=20 play +Rx5b Gx5b Lx5e here, which wins material, but leaves black without= =20 a good attack, while white can start a very powerful counter attack with= =20 the two rooks. The boat castle will soon fall to that. Therefore, Habu=20 did not think that 49.+R4a was possible and was very surprised when=20 Tanigawa played it. However, after the strong 51.P4e, the white bishop=20 has no place to go. Dropping the precious knight is the only defense. 52.N*5f 06:31:00 06:34:00 53.B*3g 06:31:00 06:34:00 54.K6b-7a 06:31:00 06:36:00 55.P4e-4d 06:52:00 06:36:00 56.S3cx4d! 06:52:00 07:06:00 Now it is Tanigawa's turn to be surprised. With this silver hanging, the= =20 white position only seems to have gotten worse. This is Habu's second=20 attempt to confuse Tanigawa... 57.B3gx4f 07:07:00 07:06:00 58.B5ex4f 07:07:00 07:06:00 59.L5gx5f? 07:07:00 07:06:00 And this time Habu succeeds. This is a serious mistake, even though it=20 was hard to foresee. Correct was 59.+Rx4d and after 60.B*3e +Rx4f Bx4f=20 R*4a Bx1i+ Lx5f +Bx2i Lx5c+ Gx5c P*5d G5c-5b B*4d S*6b S*5c black's=20 major pieces are all placed in perfect positions and black has a big=20 advantage. 60.S*4c! 07:07:00 07:19:00 It is likely that Tanigawa had only looked at 60.P*4c here, which fails=20 to 61.R*3a. The point of dropping the silver instead of the pawn is that= =20 the silver not only defends the silver on 4d, but also the gold on 5b.=20 This means that after R*3a, black is no longer threatening +Rx5b, so=20 white has an extra move, which is very important in this position. 61.R*3a 07:35:00 07:19:00 This must have been a very long 28 minutes for Tanigawa, realizing that=20 the game that he controlled for so long is slipping through his fingers.= =20 After the game, he said that he had also looked at 61.N*3f, but after=20 62.B*1d there is nothing for black. 62.B*1d 07:35:00 07:22:00 63.P*4e 07:35:00 07:22:00 64.B1dx4a 07:35:00 07:28:00 65.P4ex4d 07:35:00 07:28:00 66.S4c-3b 07:35:00 07:28:00 67.N*3c 07:38:00 07:28:00 68.R*2h 07:38:00 07:33:00 69.N3cx4a+ 07:39:00 07:33:00 70.B4f-5g+ 07:39:00 07:34:00 71.S*5i 07:41:00 07:34:00 72.+B5gx5h! 07:41:00 07:36:00 Habu wants to stop the black attack and the first step is to get both=20 rooks. After 72.+B5f Rx3b+ things get complicated again. 73.S5ix5h 07:41:00 07:36:00 74.G*2a 07:41:00 07:36:00 75.P4d-4c+ 07:47:00 07:36:00 76.G5bx4c 07:47:00 07:36:00 77.B*1h 07:47:00 07:36:00 78.G2ax3a 07:47:00 07:45:00 79.+N4ax3a 07:47:00 07:45:00 80.S3b-3c 07:47:00 07:46:00 81.B*3g 07:48:00 07:46:00 82.R2h-2b+ 07:48:00 07:47:00 83.G*6c 07:56:00 07:47:00 84.S3c-4d 07:56:00 07:49:00 85.B3gx6d 07:56:00 07:49:00 86.P*4e 07:56:00 07:49:00 87.L5fx5c+ 07:56:00 07:49:00 88.G4cx5c 07:56:00 07:49:00 89.G6cx5c 07:56:00 07:49:00 90.P*5g 07:56:00 07:49:00 91.S5hx5g 07:57:00 07:49:00 92.P*6c 07:57:00 07:49:00 93.P*2c 07:59:00 07:49:00 94.+R2bx2c 07:59:00 07:49:00 95.G*6b 07:59:00 07:49:00 96.G6ax6b 07:59:00 07:50:00 97.G5cx6b 07:59:00 07:50:00 98.K7ax6b 07:59:00 07:50:00 99.B6d-4b+ 07:59:00 07:50:00 100.+R2c-2h 07:59:00 07:50:00 101.P*5h 07:59:00 07:50:00 102.G*5b 07:59:00 07:51:00 Resigns 07:59:00 07:51:00 If black moves the promoted bishop, L*5c is winning. Also, 103.+Bx5b=20 Kx5b G*5d fails to G*5c and black has no way to continue. Habu wins=20 three games in a row to take a 3-1 lead and only needs one more win to=20 take the Oi title from Tanigawa. With the Oza match against Moriuchi=20 starting soon, Habu will be looking to finish the match as early as=20 possible. This might be a chance for Tanigawa, but the pressure is=20 definitely on him now. In other shogi news: =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D * In C1 the third round was played and four players are still without a=20 loss: Tsukada, Miyata, Yamasaki and Nakata Hiroki. Miyata and Yamasaki=20 are looking for consecutive promotions and are very much capable of=20 doing so, but there is still a long way to go and they have to play each= =20 other in the eight round. * In the Kio challenger tournament, C2 player Anyoji upset Suzuki=20 Daisuke to reach the quarterfinals. There he will meet another A class=20 player, as he will meet the winner of the game between Kubo and Fukaura. * It was already reported on the list that amateur Segawa beat A class=20 player Kubo in the Ginga-sen. This is a quick play tournament, which=20 probably gives the amateur a slightly better chance to win than in a=20 normal tournament game, but still a remarkable achievement. Segawa will=20 play Fujii in the next round. Next week I will be away from the office, so the next Shukan Shogi=20 report will be in two weeks. Also, our web server is currently down for=20 maintenance, so my web pages can not be reached at the moment.=20 Everything should be back to normal by tomorrow.
