From: Satoshi Nagaura MXC MESH NE JP> Date: 6 apr 1999 Subject: Shogi-Sekai Article (March'99) Morishita's Account of His Own Game (No.12) Challenging Right And Escaping From Successive Defeats: The 48th Osho Championsip Tournament Black: Taku Morishita (8-dan) White: Yasumitsu Sato (Meijin) 12/14/98 @Tokyo Shogi Kaikan Opening Formation: Side Pawn Opening Of Nw-3C Style In this new year's days I participated to "Tokyu Shogi Festival In Sapporo". At "Sapporo Tokyu Department Store" Shogi Festival Of Summer And Winter has been held for 26 years since its foundation without missing any time. More than 50 times it has been held there. I really appreciate about it as a member of the professional shogi players. In addition, not only at Sapporo Tokyu but also at Nipponbashi Tokyu and Nagano Tokyu Shogi Festival has been conducted for decades. It is indeed grateful. On the other hand, it is really regretful that Nihonbashi Tokyu shut down this January. It is thoroughly terrific recession. Even in this fierce recession there are, however, still many firms which allocate their resources to Shogi like Tokyu. I sincerely entreat Shogi fans to support those firms. Now, although there came many shogi fans to Sapporo Tokyu Shogi Festival and heated atmospheres were then, Hokkaido was still cold. In 5 minutes after walking the town of Sapporo without coat, I wore a coat in a fluster since I had a headache. It was quite different from the coldness in Tokyo. Nevertheless it was heard that there were many places which were much colder than Sapporo whereas Sapporao was relatively warmer in Hokkaido. "The Land Of The North" is terrific. The present period is the time to reserve its power firmly although Hokkai do economy is damaged by Heisei's big recession. I am sincerely expecting the great jump of the northern land in the future. And, I wish my new born child, whose name is Daichi (Big Land) and who is still only crying, share its good luck with jump for the 21st Century of the big land of the north. Black: Taku Morishita White: Yasumitsu Sato (Time Limit: 4 Hours each) I had been defeated by Mr.Sato 10 times consecutively before this game. How frequently defeated I was! 10 successive defeats are too much although Meijin Sato is strong as a matter of course. I have to repay it one game by one game since nothing to do against what have already done. Regardless of the championship (challenging) right, I wanted to win this game even in that meaning. Why was, however, I defeated 10 times successively? Before then, the score with him was 5 wins and 10 losses. 10 successive defeat started at the beginning of 1995. The biggest reason might be the difference of the position to get involved in and volumes to study shogi between Mr. Sato and myself although there are many reasons. Shogi is honest. I was defeated 10 consecutive times because I was tumbled on my position toward shogi. I shall never be so again. Now, the colors are decided in advance in Osho League tournament. Side pawn opening of Nw-3C style was totally out of expectation although I was anticipating several on what types of strategies Mr.Sato would come with. 1.P-7f 2.P-3d 3.P-2f 4.P-8d 5.P-2e 6.P-8e 7.G-7h 8.G-3b 9.P-2d 10.Px2d 11.Rx2d 12.P-8f 13.Px8f 14.Rx8f 15.Rx3d 16.N-3c (DIAGRAM-1) (DIAGRAM-1) White: Yasumitsu Sato White in hand: P2 9 8 7 6 5 4 3 2 1 +---------------------------+ |wL wN wS wG wK * wS * wL |a | * * * * * * wG wB * |b |wP * wP wP wP wP wN * wP |c | * * * * * * bR * * |d | * * * * * * * * * |e | * wR bP * * * * * * |f |bP * * bP bP bP bP * bP |g | * bB bG * * * * * * |h |bL bN bS * bK bG bS bN bL |i +---------------------------+ Black: Taku Morishita Black in hand: P3 up to 8...N-3c. Bw-3c is often moved on behalf at 16.N-3c, and many new strategies are recently being developed on the Bw-3c style. ] On the other hand, Nw-3c style does not have so many records. It is, however, used by Mr.Waki(7-dan) so often that it is also called "Waki-style". This opening has still many unknown parts. It was one of the most orthodox sequences until Diagram-2. The way to take a design becomes difficult around from here. 17.K-5h 18.K-6b 19.R-3f 20.S-4b 21.G-3h 22.K-7b 23.S-4h 24.G-6b 25.P-9f 26.P-9d (DIAGRAM-2) (DIAGRAM-2) White: Yasumitsu Sato White in hand: P2 9 8 7 6 5 4 3 2 1 +---------------------------+ |wL wN wS * * * * * wL |a | * * wK wG * wS wG wB * |b | * * wP wP wP wP wN * wP |c |wP * * * * * * * * |d | * * * * * * * * * |e |bP wR bP * * * bR * * |f | * * * bP bP bP bP * bP |g | * bB bG * bK bS bG * * |h |bL bN bS * * * * bN bL |i +---------------------------+ Black: Taku Morishita Black in hand: P3 up to 13...P-9d. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Strategy has fashion. There was a time when Nw-3c type was so popular from 1989 to 1992. It did not become mature enough to establish a standard patterns, and still has many unknown parts. So, players' personality and creativity tends to appear on the games. On behalf of Pb-7e, although there is an opening to assume a low posture, I decided an agressive policy. Pw-5d is a move which Mr.Waki, who is said to be the godfather of Nw-3g style opening, strongly recomends. Although Pw-4d used to be popular, Pw-5d seems to be surely more excellent. 27.N-7g 28.R-8d 29.P-7e 30.S-8b 31.S-6h 32.P-1d 33.P-1f 34.R-2d 35.P*2g 36.P-5d (DIAGRAM-3) (DIAGRAM-3) White: Yasumitsu Sato White in hand: P2 9 8 7 6 5 4 3 2 1 +---------------------------+ |wL wN * * * * * * wL |a | * wS wK wG * wS wG wB * |b | * * wP wP * wP wN * * |c |wP * * * wP * * wR wP |d | * * bP * * * * * * |e |bP * * * * * bR * bP |f | * * bN bP bP bP bP bP * |g | * bB bG bS bK bS bG * * |h |bL * * * * * * bN bL |i +---------------------------+ Black: Taku Morishita Black in hand: P2 up to 18...P-5d. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 37.R-7f 38.P-5e 39.P-3f 40.S-5c 41.S-3g 42.S-8c 43.B-9g 44.S-6d (DIAGRAM-4) (DIAGRAM-4) White: Yasumitsu Sato White in hand: P2 9 8 7 6 5 4 3 2 1 +---------------------------+ |wL wN * * * * * * wL |a | * * wK wG * * wG wB * |b | * wS wP wP * wP wN * * |c |wP * * wS * * * wR wP |d | * * bP * wP * * * * |e |bP * bR * * * bP * bP |f |bB * bN bP bP bP bS bP * |g | * * bG bS bK * bG * * |h |bL * * * * * * bN bL |i +---------------------------+ Black: Taku Morishita Black in hand: P2 up to 22...S-6d. Every move around here is so difficult. At 41.S-3g, Pb-3e is possibly a good move. Honestly speaking, I could not see it. Although it was under groping around, the skeleton of this game was determined by an idea of interesting moves which struck me against 44.S-6d. 45.P*8d 46.Sx8d 47.P*8e 48.S-9c 49.P-6f 50.S-8b 51.P-6e 52.S-5c 53.S-6g (DIAGRAM-5) (DIAGRAM-5) White: Yasumitsu Sato White in hand: P3 9 8 7 6 5 4 3 2 1 +---------------------------+ |wL wN * * * * * * wL |a | * wS wK wG * * wG wB * |b | * * wP wP wS wP wN * * |c |wP * * * * * * wR wP |d | * bP bP bP wP * * * * |e |bP * bR * * * bP * bP |f |bB * bN bS bP bP bS bP * |g | * * bG * bK * bG * * |h |bL * * * * * * bN bL |i +---------------------------+ Black: Taku Morishita Black in hand: nothing up to 27.S-6g. It was the supprising sequence from the drop & throw of 45.P*8d to a pressure of 47.P*8e Although usually the loss of a pawn is so big that this type of sequence could not be materialized, it was done in this case because of the gain of a pawn beforehand. Pb-6f without fixing of Pb*8d~Pb*8e will conversely see being pressured by Pw-7d, Pbx7d, and Pw*7e. Diagram-5, in which the three vangurd positions from 6th file to 8 files, was thought to be OK with me. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 54.B-1c 55.S-2f 56.R-5d 57.N-3g 58.G-4b (DIAGRAM-6) (DIAGRAM-6) White: Yasumitsu Sato White in hand: P3 9 8 7 6 5 4 3 2 1 +---------------------------+ |wL wN * * * * * * wL |a | * wS wK wG * wG * * * |b | * * wP wP wS wP wN * wB |c |wP * * * wR * * * wP |d | * bP bP bP wP * * * * |e |bP * bR * * * bP bS bP |f |bB * bN bS bP bP bN bP * |g | * * bG * bK * bG * * |h |bL * * * * * * * bL |i +---------------------------+ Black: Taku Morishita Black in hand: nothing up to 29...G-4b. 54.B-1c was the move which Mr.Sato reflected first soon after the game was over. Gw-4b seemed to be an appropriate move before 54.B-1c. 55.S-2f was a shrewd move. If 56.G-4b against 55.S-2f, it goes with 57.P-1e 58.Px1e 59.Sx1e 60.R-5d 61.S-2f 62.P*1d. Although it looks like a nonchalant sequence, it is big for Black which has no pwan in hand gains a pwan there. It is as big as affecting the outcome of the game. By the way, next to 56.R-5d, the sequence 57.P-1e 58.Px1e 59.Sx1e is bad with 60.B-3a and 61.P*1d. In addition to being forced to drop a pawn, the climbing silver becomes idle. In Diagram-6 the deployment came to the peak. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 59.P-1e 60.Px1e 61.P-3e 62.B-2d 63.N-2e 64.G4b-5b 65.G-4h (DIAGRAM-7) (DIAGRAM-7) White: Yasumitsu Sato White in hand: P4 9 8 7 6 5 4 3 2 1 +---------------------------+ |wL wN * * * * * * wL |a | * wS wK wG wG * * * * |b | * * wP wP wS wP wN * * |c |wP * * * wR * * wB * |d | * bP bP bP wP * bP bN wP |e |bP * bR * * * * bS * |f |bB * bN bS bP bP * bP * |g | * * bG * bK bG * * * |h |bL * * * * * * * bL |i +---------------------------+ Black: Taku Morishita Black in hand: nothing up to 33.G-4h. It was a sequence of hard thinking from Pb-1e to Pb-3e. I would like you to cpature the feeling of the position since it is difficult to explain the retort around here. I surely percieved an effect at the move which slided the gold to Gb-4h. 66.P-1f 67.Nx3c+ 68.Bx3c 69.N*4e 70.B-4b 71.Nx5c+ 72.Bx5c 73.S-2e 74.N*3c 75.S-3d 76.P*3b (DIAGRAM-8) (DIAGRAM-8) White: Yasumitsu Sato White in hand: N P3 9 8 7 6 5 4 3 2 1 +---------------------------+ |wL wN * * * * * * wL |a | * wS wK wG wG * wP * * |b | * * wP wP wB wP wN * * |c |wP * * * wR * bS * * |d | * bP bP bP wP * bP * * |e |bP * bR * * * * * wP |f |bB * bN bS bP bP * bP * |g | * * bG * bK bG * * * |h |bL * * * * * * * bL |i +---------------------------+ Black: Taku Morishita Black in hand: S up to 38...P*3b. 62.N-2e, 63.Sx2e, and 64.Bx3e is Black's advangae with 65.R-3f. It was a great patience anyhow. Nw-3e to Pw*3b was also the best tenacity. Although I felt it straightforward, it was not easy to make the game decisive. I saw ahead deeply, again. 77.P-6d 78.Px6d 79.P-7d 80.Bx3e 81.Sx3c+ 82.Px3c 83.Px7c+ 84.Sx7c 85.P*7d 86.S-8b 87.P-8d (DIAGRAM-9) Although there was no other choice from 77.P-6d to 79.P-7d, I was still coucious. If 78.Px6d against 77.P-6d, I will be better off with 79.P-7d, 80.Px7d, 81.Sx3c+, 82.Px3c and 83.N*6f. At the position of Diagram-9 the vision of endgame came to be seen.

It was a natural sequence from 89.N*7c to 91.S*8c. If 92.Sx8c against 91.S*8c, it becomes straightforward with 93.Px8c+, 94.Kx8c, 95.Px7c+, 96.Gx7c, 97.N*8e. 100.P*7e is a ominous move. Which piece should I use to take it?

By the way, 103.Px5f against 102.Rx5f will lead me to my sudden death with 104.S*5g,105.K-3g,106. and S*4f. 109.Rx3e which took his Bishop is mate threat against my mate, and it convinced me of my victory.

Then, I become the challenger of this coming Osho Championship in addition to stopping successive loss against Mr.Sato Although right now twenty agers are holding all the championships, I as one of the thirty agers would like to do my best. As I did not play so hard in my twenty, I shall play hard from now on.
