In this report the first game of the Oza title=20 match between Habu and Sato. Two games for the price of one, as the=20 first try ended in sennichite. Habu won the replay with a commanding=20 performance.

Therefore, the general opinion is that black=20 has the better position, but the difference is only marginal. Black has=20 a Yagura castle and the climbing silver attack, but white has the solid=20 Silver Crown and has pushed the pawn to 1e, which makes the climbing=20 silver a little less effective. 49.P9g-9f 01:31:00 01:56:00 50.P9c-9d 01:31:00 02:20:00 51.P*2e 03:51:00 02:20:00 Sato takes 2 hours and 20 minutes to weigh his options and decides to go= =20 for it.

Because of the time difference and=20 because he is black, Sato doesn't want the replay, but when he tries=20 Px3d after +B4f, then +Bx2h Px3c+ G4c-3c N*2e +B6d! and the white=20 promoted bishop is holding the position together. On the other hand,=20 Habu is also not the type of player to take the easy way out with=20 sennichite. This is shown by thinking 40 minutes about 64.+B4f. Px3d is=20 too dangerous to avoid the repetition of moves.

The simple threat is 57.Bx7d+, but there is also P5e Sx5e B6c+.=20 The only move to deal with both threats is 57.B*6c, but then Bx6c+ Sx6c=20 P*3f Px3f Sx3f P*3e S4e and black has managed to start the attack with=20 the white silver in a terrible position on 6c. 58.P7d-7e 04:02:00 04:58:00 Sato uses almost all of his remaining time to start a desperate attack. 59.B4a-7d+ 04:17:00 04:58:00 60.P7ex7f 04:17:00 04:58:00 61.S7gx7f 04:17:00 04:58:00 62.P6d-6e 04:17:00 04:58:00 63.+B7d-7e 04:17:00 04:58:00 64.P6ex6f 04:17:00 04:58:00 65.+B7ex6f 04:17:00 04:58:00 66.R8b-7b 04:17:00 04:58:00 67.P*7d 04:22:00 04:58:00 68.B*4d 04:22:00 04:58:00 69.+B6fx4d 04:22:00 04:58:00 70.G3cx4d 04:22:00 04:58:00 71.P2e-2d 04:35:00 04:58:00 72.P2cx2d 04:35:00 04:58:00 73.B*7g! 04:37:00 04:58:00 The threat is P*7e Sx7e B*3i and the obvious move is to defend against=20 this with 73.B*6f. What Habu has in mind with 73.B*7g is a very high=20 level technique, even for professionals. The reason will become clear soon.= 74.G3b-3c?! 04:37:00 04:58:00 Better was 74.B*3c, which keeps the white position safe, but then white=20 voluntarily gives up the threat P*7e Sx7e B*3i, so only very few=20 professionals will play 74.B*3c. Play may continue 75.P*2e Px2e N3g=20 G4d-4c and the position is unclear. 75.R2h-6h! 04:37:00 04:58:00 Defends against the white threat and makes a threat of his own by G5g=20 followed by R6a+. Because white has played 74.G3b-3c, allowing a rook=20 promotion is out of the question. The white king is just too weakly=20 defended from the side. 76.R7b-6b 04:37:00 04:58:00 77.B7g-6f! 04:37:00 04:58:00 This is really the brilliant part of Habu's play. First not dropping the= =20 bishop on 6f but on 7g and then moving it up to 6f here. This looks like= =20 losing a move, but the big difference is the white rook on 6b. Black is=20 now threatening Bx8d. Sato can't really be blamed for overlooking this=20 subtle play because of the time trouble he is in, but Habu probably used= =20 only 13 minutes to find it (the time he used for 71.P2d). 78.G4d-4c 04:37:00 04:59:00 79.G6g-7g 04:41:00 04:59:00 80.P*6e 04:41:00 04:59:00 81.B6fx8d 04:41:00 04:59:00 82.R6b-6a 04:41:00 04:59:00 83.P7d-7c+ 04:41:00 04:59:00 84.B*9c 04:41:00 04:59:00 85.B8dx9c+ 04:41:00 04:59:00 86.N8ax9c 04:41:00 04:59:00 87.B*8c 04:42:00 04:59:00 88.R6a-7a 04:42:00 04:59:00 89.B8c-7d+ 04:42:00 04:59:00 90.B*5g 04:42:00 04:59:00 91.R6h-3h 04:42:00 04:59:00 92.P*7e 04:42:00 04:59:00 93.S7f-6g 04:42:00 04:59:00 94.P*4e 04:42:00 04:59:00 95.P*6d 04:42:00 04:59:00 96.P4ex4f 04:42:00 04:59:00 97.S4g-5h 04:42:00 04:59:00 98.P4f-4g+ 04:42:00 04:59:00 99.S5hx4g 04:42:00 04:59:00 100.P3e-3f 04:42:00 04:59:00 101.P6d-6c+ 04:42:00 04:59:00 102.P3f-3g+ 04:42:00 04:59:00 103.N2ix3g 04:43:00 04:59:00 104.P*3f 04:43:00 04:59:00 105.S4gx3f 04:43:00 04:59:00 106.B5g-4f+ 04:43:00 04:59:00 107.P*3e 04:43:00 04:59:00 108.S3d-2c 04:43:00 04:59:00 109.P*4d 04:43:00 04:59:00 110.G4cx4d 04:43:00 04:59:00 111.+P7c-7b 04:43:00 04:59:00 112.R7a-3a 04:43:00 04:59:00 113.+P6cx5c 04:43:00 04:59:00 114.+B4fx3f 04:43:00 04:59:00 115.+P5c-4b 04:43:00 04:59:00 This seems to end the game, but Sato is not ready to resign yet. 116.R3a-3b! 04:43:00 04:59:00 A full rook sacrifice, but with this the white position gets back into=20 order and the black attack is delayed.

Sato showed a lot of fighting spirit again, but Habu=20 dictated the replay from the start. The fact that there was a replay in=20 this game has no relation to the second game, which means that Habu can=20 play with the black pieces again in game 2. A good opportunity to take a= =20 2-0 lead and a big step forward to winning his 14th consecutive Oza title. --=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: ------------------------------------------------------------------- Oprah vs Dr. Phil- who is your favorite?
