A game that Habu had to win, because he was down 2-0 and until now nobody had ever come back from 3-0 down. Despite being with his back against the wall, Habu played some good, positive shogi to get back to 2-1. Here is the game with comments: [Black "Habu Yoshiharu, Meijin"] [White "Moriuchi Toshiyuki, Challenger"] [Event "62nd Meijin-sen, Game 3"] [Date "May 12th and 13th 2004"] 1.P7g-7f 00:00:00 00:00:00 2.P3c-3d 00:00:00 00:02:00 3.P2g-2f 00:01:00 00:02:00 4.P1c-1d 00:01:00 00:02:00 Already an important point in the game. Moriuchi is aiming for the Kakugawari opening without pushing the pawn to 8e. Delaying the pawn push to 8d is an important first step in this strategy. Black has many replies to 4.P1d, but all of them have drawbacks. 5.G7h has been played here, but then white plays a ranging rook opening, in which the black gold does not belong on 7h. 5.S4h is another option, but then black can not longer play the climbing silver, limited his options. Then why not answer P1d with P1f? This move has its own problems, depending on the opening played. For example, after the waiting move 5.P1f, white can try to get in the Ai-Yokofudori opening. There are variations in which white can not switch the rook to 2f because of the fork on king and rook B*1e. With the pawn on 1d, this check is not possible, so black has to defend the knight on 2i in that case with the pawn drop P*2h, which is good for white. Subtle, but it is one of the reasons professionals do not want to answer 4.P1d with 5.P1f. 5.P2f-2e 00:25:00 00:02:00 This is the most natural move, but has the drawback that black can no longer play the attack N2e later. 6.B2bx8h+ 00:25:00 00:03:00 7.S7ix8h 00:25:00 00:03:00 8.S3a-2b 00:25:00 00:03:00 9.S3i-4h 00:28:00 00:03:00 10.S2b-3c 00:28:00 00:06:00 11.K5i-6h 00:30:00 00:06:00 12.S7a-6b 00:30:00 00:22:00 13.S8h-7g 00:34:00 00:22:00 14.G4a-3b 00:34:00 00:36:00 15.P3g-3f 01:00:00 00:36:00 16.P8c-8d 01:00:00 01:04:00 17.G6i-7h 01:26:00 01:04:00 18.P9c-9d 01:26:00 01:15:00 19.P9g-9f 02:03:00 01:15:00 20.P7c-7d 02:03:00 01:41:00 21.P4g-4f 02:12:00 01:41:00 22.P6c-6d 02:12:00 01:50:00 23.P1g-1f 02:20:00 01:50:00 24.S6b-6c 02:20:00 02:03:00 25.S4h-4g 02:29:00 02:03:00 26.K5a-4b 02:29:00 02:06:00 27.G4i-5h 02:53:00 02:06:00 28.G6a-5b 02:53:00 02:38:00 29.S4g-5f 03:23:00 02:38:00 30.S6c-5d 03:23:00 03:49:00 The difficulty of the one-tempo-loss Kakugawari is illustrated by the slow pace of the game. This is the sealed move. Both players have not shown their hand yet. 31.K6h-7i 03:45:00 03:49:00 32.R8b-6b 03:45:00 04:17:00 The main idea of the white opening strategy becomes clear after 32.N7c P6f P4d K3a. With the pawn on 8e, black can then start the fight with P4e, P2d and P7e. Particularly, because of the weakness of 7d, white has to answer P7e with G6c and is put on the defensive. However, with the pawn still on 8d, white can just take the pawn on 7e and answer P*7d with the counter attack N8e. Moriuchi might have found a problem with the move sequence N7c P6f P4d K3a, because he played 32.R6b instead. 33.P6g-6f 05:36:00 04:17:00 34.K4b-3a 05:36:00 04:18:00 35.N2i-3g 05:36:00 04:18:00 36.N8a-7c 05:36:00 04:45:00 37.S7g-8f! 05:57:00 04:45:00 Strange looking, but a good move. 37.K8h P6e or 37.P7e N8e are both good for white. 37.S8f is threatening to attack with P7e, more or less forcing the next move. Playing 37.S8f first is the correct move order. If 37.P7e Px7e S8f, then after P7f S7e G6c, the pawn on 7f becomes an important base for the white attack. 38.G5b-6c 05:57:00 05:14:00 This gold is now pulled away from the white king, which is an important weakness. 39.S8f-7g 06:00:00 05:14:00 40.R6b-8b 06:00:00 05:20:00 41.K7i-8h 06:02:00 05:20:00 42.K3a-4b 06:02:00 05:25:00 43.G5h-6g 06:15:00 05:25:00 44.K4b-3a 06:15:00 05:31:00 45.G6g-6h 06:23:00 05:31:00 46.K3a-4b 06:23:00 05:46:00 Both players seem to be waiting, and sennichite is in the air... 47.S5f-4e! 07:12:00 05:46:00 Positive play. After the game, Habu said he had thought about sennichite here, but that the game had not even been opened up yet, so he decided to go for it. This is the perfect time to attack. With the king on 3a, the black attack has to come from to far to have good chances of success. With the king on 4b, however, the black attack can succeed. When the position is getting sharp, the white pawn on 8d is a handicap. The quickest white counter attack starts by playing P8f or N*8f (with the pawn on 8e), which is not possible here. Also, after a silver drop on 7a, white can not move up the rook to 8d. 48.S5d-5e 07:12:00 06:05:00 49.S4e-5f 07:13:00 06:05:00 50.S5ex4f 07:13:00 06:21:00 51.N3g-4e 07:13:00 06:21:00 52.S3c-4d 07:13:00 06:23:00 53.P2e-2d 07:15:00 06:23:00 54.P2cx2d 07:15:00 06:23:00 55.R2hx2d 07:21:00 06:23:00 56.P*2c 07:21:00 06:24:00 57.R2dx3d 07:22:00 06:24:00 58.P9d-9e 07:22:00 06:37:00 59.P9fx9e 07:33:00 06:37:00 60.N2a-3c 07:33:00 06:46:00 61.P*4g! 07:38:00 06:46:00 Again well judged by Habu. Drawing away the silver, followed by attacking at the other side of the board is the correct way of playing here. 62.S4f-3g= 07:38:00 07:15:00 63.P6f-6e 07:43:00 07:15:00 64.P*9g 07:43:00 07:57:00 No choice but to go for a desperate counter attack. 64.Nx4e fails to 65.Px6d G6b Sx4e Sx4e B*5a Kx5a Rx3b+ and even though black is almost a full bishop down, his castle is rock solid and white has no defense against the promoted rook. 65.P6ex6d 08:08:00 07:57:00 66.G6cx6d 08:08:00 07:58:00 67.B*7a 08:09:00 07:58:00 68.R8b-5b 08:09:00 08:00:00 69.P*6b 08:09:00 08:00:00 70.N3cx4e 08:09:00 08:05:00 71.P6b-6a+ 08:09:00 08:05:00 72.P5c-5d 08:09:00 08:32:00 73.+P6a-6b 08:19:00 08:32:00 This tokin attack decides the game. 74.R5b-5c 08:19:00 08:32:00 75.+P6b-7b 08:19:00 08:32:00 76.P*3c 08:19:00 08:37:00 77.R3dx4d 08:23:00 08:37:00 78.P4cx4d 08:23:00 08:37:00 79.B7ax5c+ 08:24:00 08:37:00 80.K4bx5c 08:24:00 08:37:00 81.R*6b 08:27:00 08:37:00 82.N*9f 08:27:00 08:42:00 83.K8hx9g 08:30:00 08:42:00 84.N7c-8e 08:30:00 08:50:00 85.K9gx9f 08:30:00 08:50:00 86.N8ex7g+ 08:30:00 08:51:00 87.N8ix7g 08:30:00 08:51:00 88.S*8c 08:30:00 08:54:00 89.N*6e 08:36:00 08:54:00 Resigns 08:36:00 08:56:00 Moriuchi has tried everything and even managed to create a mating threat. However, 89.N*6e is the perfect answer. 90.Gx6e Nx6e K4c S*5b leads to mate, while 90.K4c Rx6d+ defends against the mating threat and threatens mate, leaving white without any hope. A fine game by Habu, who showed a very positive attitude in this important game. He is still 2-1 down, so the next game is just as important. In other shogi news: ==================== * In the white group of Oi league, Yamasaki clinched the group victory with a win against Yashiki. Quite a performance, because this was a strong group with Moriuchi, Maruyama, Senzaki and Hatakeyama Mamoru as the other members. Winning the group with one game left to play shows young Yamasaki's exceptional talent. He will now play the winner of the red group for the right to challenge Tanigawa. * In the Ryu-O tournament, two more names were added to the challenger tournament. Senzaki beat Hiura to reach the final of the second qualification group, which ensures entry in the challenger knock-out. Senzaki is not new to this, qualifying for the 4th time, but the last time was already 7 years ago. The other player to qualify was Kamiya, who beat Kitajima to reach the final of the third qualification group. For Kamiya it was also a long time ago, because his first and last appearance in the challenger knock-out tournament was 12 years ago. * In the Oza challenger tournament, Goda reached the second round by beating Senzaki. This game had a rather unusual endgame, where both players thought there was no defense for Goda's king. However, he managed to escape and win nonetheless. Even the post-mortem analysis could not reveal a clear win for Senzaki.
