A game Habu desperately needed to win, but there were no signs of=20 pressure at all. He trusted his own judgment, playing an attack that=20 only he thought was playable and topped it off with some old-fashioned=20 Habu magic. No chance for Tanigawa in this game, but the match has only=20 just started. Here is the game with comments: [Black "Tanigawa Koji, Oi"] [White "Habu Yoshiharu, Challenger"] [Event "45th Oi-sen, Game 2"] [Date "July 27th and 28th 2004"] 1.P7g-7f 00:00:00 00:00:00 2.P8c-8d 00:00:00 00:06:00 3.P5g-5f 00:15:00 00:06:00 4.P3c-3d 00:15:00 00:43:00 5.P5f-5e 00:20:00 00:43:00 6.S7a-6b 00:20:00 00:44:00 7.R2h-5h 00:25:00 00:44:00 After Habu's Quick Ishida in game 1, again a furibisha opening. This=20 time Tanigawa plays the Gokigen Nakabisha. 8.K5a-4b 00:25:00 00:49:00 9.K5i-4h 00:30:00 00:49:00 10.K4b-3b 00:30:00 00:55:00 11.K4h-3h 00:32:00 00:55:00 12.S3a-4b 00:32:00 00:59:00 13.B8h-7g 00:55:00 00:59:00 14.P6c-6d 00:55:00 01:22:00 15.S7i-6h 01:04:00 01:22:00 16.S6b-6c 01:04:00 01:25:00 17.K3h-2h 01:10:00 01:25:00 18.G6a-5b 01:10:00 01:35:00 19.S3i-3h 01:23:00 01:35:00 20.S4b-3c 01:23:00 02:02:00 Looks like a questionable move, but this makes it difficult for black to= =20 develop his pieces by P5d, because this no longer threatens the exchange= =20 of the bishops. 21.S6h-5g 02:05:00 02:02:00 22.S6c-7d 02:05:00 02:44:00 After 20.S3c another strange looking silver move, but this move aims at=20 the undefende pawn on 7f, so black can not take this lightly. This use=20 of the silver has been played before, but in this game neither side has=20 pushed the edge pawn on the king side, which makes this exact position a= =20 first. From this game it is hard to judge if this is a significant=20 difference. 23.S5g-5f 02:37:00 02:44:00 24.S7d-8e!? 02:37:00 03:11:00 The start of a risky silver attack. Even Habu admitted after the game=20 that he had not idea if this was good or bad. 25.P7f-7e 02:45:00 03:11:00 26.S8e-7f 02:45:00 04:03:00 27.B7g-6h 02:48:00 04:03:00 28.S7fx8g=3D 02:48:00 04:20:00 White has won a pawn, but the silver on 8g is completely out of play.=20 Furthermore, it will take quite a lot of time to activate this silver,=20 because S7f+ can be answered by R7h, after which the silver has to go=20 back to 8g. White has to wait until black plays 6f before S7f+ is=20 possible. All of the commentators in the press room and Tanigawa himself= =20 thought that white's silver attack was an overplay and that black could=20 get the advantage by opening the game while the silver is still on 8g. 29.B6h-4f 03:24:00 04:20:00 The sealed move. 30.S3c-4d 03:24:00 04:25:00 31.P7e-7d 04:03:00 04:25:00 32.G5b-6c 04:03:00 04:51:00 33.P7dx7c+ 04:25:00 04:51:00 34.N8ax7c 04:25:00 04:52:00 35.P6g-6f 04:26:00 04:52:00 36.S8g-7f+ 04:26:00 04:55:00 37.R5h-6h 05:05:00 04:55:00 Here Tanigawa realized that things were not that simple. Black seems to=20 have all kinds of good moves here, but none of them work: 1) 37.R7h=20 +Sx6f P*7d P*7b wins a knight, but leaves black without pawns; 2) 37.P6e= =20 Nx6e P5d Gx5d and black has no continuation; 3) 37.P5d Px5d P6e=20 (changing the order of the previous variation) is met by P5e Sx5e P*5g=20 Rx5g Nx6e R5f Sx5e Bx5e Bx5e Rx5e B*6f and after the rook moves, white=20 has N5g=3D. In the end, Tanigawa decided to admit strategic defeat and=20 play the quiet 37.R6h, patiently waiting for a chance, which seems=20 likely to come with several weaknesses in the white camp. 38.+S7f-7e 05:05:00 05:23:00 39.P*7f 05:42:00 05:23:00 40.+S7ex7f 05:42:00 06:08:00 41.P6f-6e 05:42:00 06:08:00 42.P6dx6e 05:42:00 06:15:00 43.P5e-5d 05:42:00 06:15:00 44.P6e-6f 05:42:00 06:15:00 45.P5dx5c+ 06:42:00 06:15:00 46.S4dx5c 06:42:00 06:15:00 47.S5f-6e 06:42:00 06:15:00 48.P6f-6g+ 06:42:00 06:30:00 49.P*6d 06:43:00 06:30:00 50.G6c-6b 06:43:00 06:31:00 51.S6ex7f 06:43:00 06:31:00 52.+P6gx6h 06:43:00 06:31:00 53.G6ix6h 06:43:00 06:31:00 54.R*7i!! 06:43:00 06:36:00 Habu magic. Everybody (including Tanigawa) expected 54.Bx9a+ after which= =20 black has fighting chances. Tanigawa had planned 55.P*7d and if play=20 continues 56.L*4d P6c+ Gx6c Px7c+ Lx4f +Px6c the position is unclear.=20 Habu decides to return the material he gained to play L*4d without white= =20 getting a chance to attack the head of the knight. Brilliant judgment=20 that basically ends this game. White never gets a decent counter attack=20 going. 55.S*7h 07:06:00 06:36:00 56.B2bx9i+ 07:06:00 06:42:00 57.G6h-6i 07:07:00 06:42:00 58.R7ix6i+ 07:07:00 06:42:00 59.S7hx6i 07:07:00 06:42:00 60.L*4d 07:07:00 06:42:00 61.B4f-6h 07:13:00 06:42:00 62.+B9i-6f! 07:13:00 07:14:00 Another blow. This promoted bishop picks up a silver and controls the board= . 63.P*7d 07:13:00 07:14:00 64.+B6fx7f 07:13:00 07:14:00 65.P7dx7c+ 07:13:00 07:14:00 66.G6bx7c 07:13:00 07:14:00 67.P6d-6c+ 07:25:00 07:14:00 68.G7cx6c 07:25:00 07:19:00 69.R*7a 07:25:00 07:19:00 70.+B7f-6e 07:25:00 07:20:00 71.R7ax9a+ 07:29:00 07:20:00 72.+B6e-9b 07:29:00 07:20:00 73.+R9ax9b 07:30:00 07:20:00 74.R8bx9b 07:30:00 07:20:00 75.B*8c 07:30:00 07:20:00 76.R9b-6b 07:30:00 07:21:00 77.B8c-5f+ 07:30:00 07:21:00 78.G6c-5d 07:30:00 07:22:00 79.+B5fx3d 07:33:00 07:22:00 80.P*3c 07:33:00 07:27:00 81.+B3d-5f 07:37:00 07:27:00 82.P*5e 07:37:00 07:28:00 83.+B5f-7d 07:37:00 07:28:00 84.R6b-6g+ 07:37:00 07:28:00 Resigns 07:40:00 07:28:00 The material difference in this position is small, but white has no=20 decent attacking moves (for example, N*1e is answered by P*6c). On the=20 other hand, black can choose from moves like P5f and R*8h, which will=20 quickly destroy the black position. Tanigawa took three minutes before=20 resigning, but saw no point in playing any further. After the game he=20 admitted that he had no idea what had gone wrong and that probably the=20 position at the end of the first day was already bad for black. --=20 Reijer Grimbergen Department of Informatics, Yamagata University Jonan 4-3-16, Yonezawa, 992-8510 Japan Tel: +81-(0)238-26-3740 FAX: +81-(0)238-26-3299 http://gamelab.yz.yamagata-u.ac.jp/ Your free subscription is supported by today's sponsor: ------------------------------------------------------------------- Buy Stocks and Index Funds for just $4 No Account or=20 Investment Minimums and No Inactivity Fees Automatically=20 invest weekly or monthly and build your future. http://click.topica.com/= caacvgga2i6YsbnuqMaf/Sharebuilder ------------------------------------------------------------------- --^---------------------------------------------------------------- This email was sent to: = shogi-l shogi net EASY UNSUBSCRIBE click here: http://topica.com/u/?a2i6Ys.= bnuqMa.= c2hvZ2kt Or send an email to: shogi-unsubscribe topica com For Topica's complete suite of email marketing solutions visit: http://www.topica.com/?p=3DTEXFOOTER --^----------------------------------------------------------------
