From: Reijer Grimbergen FU IS SAGA-U AC JP> Date: 31 oct 2002 Subject: This week in Shukan Shogi (no. 966, October 30th 2002) (revised) Oops. I forgot to include the second sennichite game in my previous post. Here is the revised Shukan Shogi report: ----------------------------------------------------------- In this week's Shukan Shogi the somewhat disappointing start of the Ryu-O match between Habu and Abe. Playing in Taiwan couldn't inspire the players to really go at each other's throat and the first game ended in consecutive sennichite. Here are the games with comments: Black: Habu Yoshiharu, Ryu-O White: Abe Takashi, Challenger 15th Ryu-O sen, Game 1, October 23rd and 24th 2002 1.P7g-7f 00:01:00 00:00:00 2.P3c-3d 00:01:00 00:02:00 3.P2g-2f 00:03:00 00:02:00 4.P5c-5d 00:03:00 00:03:00 A surprise. The Gokigen-Nakabisha is very popular at the moment, but Abe is not known to use it very often. Abe likes to play quick Yagura variations with white and in the Ryu-O challenger final against Nakata he played the R8e-Yokofudori. He has only played the Gokigen-Nakabisha twice: in January against Fukaura and in June against Nakahara. Both games were in quick play tournaments, indicating that Abe believed that the sharp variations of the Gokigen-Nakabisha were more suited for quick games than for games with long thinking time. It seems he changed his mind in the weeks up to his first title match. By choosing this opening he makes clear that he is not willing to wait for Habu to come to him. Everybody sees Habu as the favourite in this match, but Abe will not go down without a fight. 5.P2f-2e 00:21:00 00:03:00 Habu was surprised, too. He took 18 minutes for this move. 6.R8b-5b 00:21:00 00:07:00 7.G6i-7h 00:25:00 00:07:00 8.K5a-6b 00:25:00 00:31:00 9.K5i-6i 00:33:00 00:31:00 10.K6b-7b 00:33:00 00:33:00 11.S3i-4h 00:34:00 00:33:00 12.P5d-5e 00:34:00 01:17:00 13.P2e-2d 00:53:00 01:17:00 14.P2cx2d 00:53:00 01:17:00 15.R2hx2d 00:53:00 01:17:00 16.G4a-3b 00:53:00 01:17:00 17.S7i-6h 01:11:00 01:17:00 18.K7b-8b 01:11:00 02:06:00 19.R2d-2h 01:33:00 02:06:00 20.P*2c 01:33:00 02:07:00 21.P4g-4f 01:35:00 02:07:00 22.P3d-3e 01:35:00 02:13:00 23.S4h-4g 01:57:00 02:13:00 24.S7a-7b 01:57:00 02:23:00 25.P6g-6f 02:46:00 02:23:00 26.R5b-5d 02:46:00 03:05:00 27.G7h-6g 03:15:00 03:05:00 28.S3a-4b 03:15:00 03:45:00 29.P5g-5f 03:56:00 03:45:00 The sealed move and a surprise. 29.K7h was the expected move. Habu wants to play this position more positively. 30.P5ex5f 03:56:00 04:50:00 31.G6gx5f 03:56:00 04:50:00 32.R5d-5a 03:56:00 04:57:00 33.K6i-7h?! 04:25:00 04:57:00 Questionable. Habu regretted playing this move. After the game he said that he should have played 33.G4e, putting pressure on white's major pieces 34.P6c-6d 04:25:00 05:29:00 35.G4i-5h 05:42:00 05:29:00 36.S4b-5c 05:42:00 05:44:00 37.G5h-6g 05:47:00 05:44:00 38.S5c-5d 05:47:00 05:48:00 39.P9g-9f 05:48:00 05:48:00 40.S7b-6c 05:48:00 06:23:00 41.P3g-3f 05:54:00 06:23:00 42.G6a-7b 05:54:00 06:28:00 43.P3fx3e 05:55:00 06:28:00 44.P7c-7d 05:55:00 06:30:00 45.G5f-5g 06:26:00 06:30:00 46.P*5e 06:26:00 06:37:00 47.N8i-7g 06:30:00 06:37:00 Blocks the bishop, but black has no choice. Allowing the pawn exchange P6e would be good for white. 48.N8a-7c 06:30:00 06:41:00 49.P3e-3d 06:35:00 06:41:00 50.P9c-9d 06:35:00 06:46:00 51.N2i-3g 06:44:00 06:46:00 52.P8c-8d 06:44:00 06:56:00 53.R2h-3h 06:51:00 06:56:00 54.G3b-4b 06:51:00 07:05:00 Defending against P3c+ Bx3c N2e. With the gold still on 3b, the bishop can't move in this position. 55.R3h-2h 07:06:00 07:05:00 It seems that black can start the fight here with 55.N2e, but Habu had seen that after 56.B4d P*2b Bx2b P2d Px2d N3c+ Nx3c P*3c white has the strong P*3g!. If black takes this pawn with Rx3g then white can play N2e and if black moves the rook with R2h, then B3a is good for white. Habu decides to acknowledge his strategical mistake on the 33th move and try his luck in a replay with reversed colours. 56.G4b-3b 07:06:00 07:05:00 57.R2h-3h 07:06:00 07:05:00 58.G3b-4b 07:06:00 07:05:00 59.R3h-2h 07:06:00 07:05:00 60.G4b-3b 07:06:00 07:05:00 61.R2h-3h 07:06:00 07:05:00 62.G3b-4b 07:06:00 07:05:00 63.R3h-2h 07:06:00 07:05:00 64.G4b-3b 07:06:00 07:05:00 Sennichite 07:06:00 07:05:00 A small psychological victory for challenger Abe. Habu has not been able to put him under real pressure with black. Black: Abe Takashi, Challenger White: Habu Yoshiharu, Ryu-O 15th Ryu-O sen, Replay Game 1, October 24th 2002 1.P7g-7f 05:59:00 00:00:00 2.P8c-8d 05:59:00 06:01:00 Most Sennichite replays start with a minimum of one hour per player. In the Ryu-O the minimal time per player is two hours. Habu used one minute more than Habu for the first game, so he starts with two hours left on the clock, while Abe starts with two hours and one minute. 3.S7i-6h 06:00:00 06:01:00 4.P3c-3d 06:00:00 06:01:00 5.S6h-7g 06:00:00 06:01:00 6.S7a-6b 06:00:00 06:02:00 7.P5g-5f 06:00:00 06:02:00 8.P5c-5d 06:00:00 06:03:00 9.S3i-4h 06:00:00 06:03:00 10.S3a-4b 06:00:00 06:04:00 11.P2g-2f 06:01:00 06:04:00 12.G6a-5b 06:01:00 06:05:00 13.G4i-5h 06:03:00 06:05:00 14.G4a-3b 06:03:00 06:13:00 15.P6g-6f 06:06:00 06:13:00 16.K5a-4a 06:06:00 06:13:00 17.G5h-6g 06:06:00 06:13:00 18.P7c-7d 06:06:00 06:15:00 19.B8h-7i 06:15:00 06:15:00 20.S4b-3c 06:15:00 06:18:00 21.P3g-3f 06:21:00 06:18:00 22.B2b-3a 06:21:00 06:30:00 23.G6i-7h 06:34:00 06:30:00 24.P4c-4d 06:34:00 06:30:00 25.K5i-6i 06:34:00 06:30:00 26.G5b-4c 06:34:00 06:30:00 27.B7i-4f 06:35:00 06:30:00 28.B3a-6d 06:35:00 06:36:00 29.P2f-2e 06:38:00 06:36:00 30.P8d-8e 06:38:00 06:36:00 31.B4f-3g 06:39:00 06:36:00 32.B6d-7c 06:39:00 06:44:00 33.K6i-7i 06:40:00 06:44:00 34.K4a-3a 06:40:00 06:44:00 35.P1g-1f 06:44:00 06:44:00 36.P9c-9d 06:44:00 06:47:00 37.P9g-9f 07:00:00 06:47:00 This is a Yagura variation that was popular about 20 years ago. It is hardy played anymore because the symmetrical position easily leads to positions where sennichite is the only possible result. It seems strange that Abe would play such a variation in the replay of a sennichite game, but he had actually prepared something in this variation. 38.P6c-6d 07:00:00 07:02:00 39.S4h-5g 07:06:00 07:02:00 40.S6b-5c 07:06:00 07:02:00 41.P4g-4f 07:08:00 07:02:00 42.B7c-8d 07:08:00 07:07:00 43.B3g-2f 07:09:00 07:07:00 44.S3c-2b! 07:09:00 07:15:00 There goes Abe's preparation. He was aiming for a symmetrical position with both kings in the Yagura castle, the rooks on 4i and 6a, knight on 3g and 7c and pawns on 4e and 6e. It seems like he had prepared a way to attack strongly in that type of position. 44.S3b doesn't allow this attack, as N3c next makes P4e impossible. 45.S7g-8h 07:16:00 07:15:00 Now Abe has to admit his strategic failure. The position stays symmetrical and closed. 46.P1c-1d 07:16:00 07:19:00 47.N8i-7g 07:20:00 07:19:00 48.N8a-7c 07:20:00 07:19:00 49.N2i-3g 07:32:00 07:19:00 50.N2a-3c 07:32:00 07:19:00 51.K7i-8i 07:32:00 07:19:00 52.K3a-2a 07:32:00 07:22:00 53.R2h-2i 07:35:00 07:22:00 54.R8b-8a 07:35:00 07:33:00 55.R2i-2h 07:38:00 07:33:00 There we go again. The alternative is 55.R4i, but after 56.R6a P4e, the black attack backfires after Px4e Nx4e Nx4e Rx4e P*4d R4i P6e Px6e Nx6e Rx6e P*6f Rx2e. 56.R8a-8b 07:38:00 07:41:00 57.R2h-2i 07:38:00 07:41:00 58.R8b-8a 07:38:00 07:41:00 59.R2i-2h 07:38:00 07:41:00 60.R8a-8b 07:38:00 07:41:00 61.R2h-2i 07:38:00 07:41:00 62.R8b-8a 07:38:00 07:41:00 63.R2i-2h 07:38:00 07:41:00 64.R8a-8b 07:38:00 07:41:00 Sennichite 07:38:00 07:41:00 And with this second sennichite this Ryu-O match starts with a non-contest. Game 1 will be replayed on the days that were scheduled for Game 2. If this match is going to take seven games, the organizers will be in trouble, as they will have to find a new date and place for game 7. Game 6 will now be played on Christmas day, and there will be little time to play a seventh game between Christmas and the long New Year holiday. In other shogi news: ==================== * In B1 Junisen the sixth round was played. Senzaki had taken the lead in round five by beating undefeated Kubo, but played to optimistically against Suzuki and fell back to 4-2. The other two leaders Kubo and Inoue made no mistake and they now lead the promotion race. They are followed by Senzaki, Suzuki and Fukaura. It seems likely that two of these five players will play in the top division next year. * In B2 leader Hatakeyama Nariyuki lost against Kimura, and now all players in this class have at least one loss after five rounds. Nakagawa and Kitahama are back in the lead, but Izumi, Tamaru and the Hatakeyama twins also have 4-1 scores and every chance of promoting to B1. This is going to be a hard one to predict, but it would be kind of interesting if both Hatakeyama brothers would promote to B1 at the same time. * In C2 the sixth round was played. Leaders Iijima, Kubota and Ueno didn't make a mistake and still occupy the promotion spots after winning their first five games. They are followed by Tamaru at 5-1. Chuza, Yamasaki, Akutsu, Watanabe, Kondo, Hashimoto and Kawakami are following with 4-1. * Maruyama is the first player to reach the semi-finals of the Kio challenger tournament. He beat Nakata Hiroki in 129 moves and will now play the winner of the game between Tanaka Torahiko and Iizuka. * In the Osho league Goda recovered from a first round loss against Habu with a victory against Fujii. Fujii showed how tight this year's Osho league might be by bouncing back from two losses with a fine win over Meijin Moriuchi. Only Habu and Morishita are without loss in the league, but they have only played one game so far.
