From: Reijer Grimbergen ETL GO JP> Date: 14 jul 1998 Subject: Amateur Ryu-O Report (Long) As promised, here is my report on the amateur Ryu-O tournament that was played on June 27th and 28th. It is quite long, so I apologize to everyone who might not be interested in my experiences in this top amateur tournament. This report can also be found at: http://www.etl.go.jp/etl/suiron/~grimberg/SHOGI/amaryu98.html Reijer ****************************************************************************** The 11th Amateur Ryu-O Tournament ================================= The build-up ------------ On the Thursday before the start of the 11th Amateur Ryu-O Tournament, I did not know any better than that I would spent the weekend of June 27th and 28th playing and watching football. The world cup in France was starting to become interesting with the pre-round matches almost completed. Also, with my own team we had to play one of our main rivals, a tough team from a neighboring research institute. An E-mail message with the subject "Invitation to the Ryu-O" changed all that. At first I thought it was an invitation to come and watch the games, supporting Mr. Kyo, the Chinese player who was invited this year. However, it turned out to be a message from Onogi from the Shogi Renmei, who asked me to replace Mr. Kyo in the tournament. With pain in my heart I informed our team captain that urgent business kept me from playing (they lost 2-1 and even worse: they found out that I had given shogi priority over football). This was a chance I was not going to miss. I arrived at around 6 o'clock on Friday evening at the Urashima Hotel where the tournament was going to be held. I was welcomed by Onogi and Horiguchi of the Shogi Renmei and Yamada and Oda of the Yomiuri Shimbun, the organizers of the Ryu-O tournament. There were only three spots left and I ended up in a group that seemed to give some hope. In the first round I had to play a very strong opponent, but I was also in the same group as the representative of Okinawa, the smallest prefecture in Japan. That might be my opponent in the second game... But first there was the pre-tournament party held on Friday evening. As usual, there were quite a number of speeches. Professional Ryu-O Tanigawa had some very nice words for me. He said that even though he was supposed to be neutral as the main referee, he would still be supporting me. During the reception I also heard that Mr. Kyo could not come because he had been too late in requesting a visa. In China it seems to take two months to get a visa application approved. After the reception there was a small afterparty with Tanigawa, Oda and co-organizer Tanabe (professional 6-dan). Still tired from watching the Holland-Mexico game the evening before, I retired early. I was hoping that my opponents would watch the Japan against Jamaica game that night, so that at least I would have some extra hours of sleep as a small compensation for my lack of Shogi strength. The first round --------------- When I went downstairs for breakfast on Saturday morning, I met Nishimoto, the strong representative from Hyogo-ken, in the elevator. He had planned to go to sleep early, but in the end he watched the complete Japan-Jamaica game. Japan had surprisingly lost 2-1 and retired from the world cup with three losses. Good, I thought, at least the football fans will be depressed. Another badly needed psychological advantage. The tournament system of the amateur Ryu-O tournament has not changed since the beginning. First, every player plays in a group of four. The winners and the losers of the first game in this group play against each other. The player who wins two games in a row automatically qualifies for the knock-out tournament. The player who loses two consecutive games goes home. The players who have won one game and lost one game play against the players with a 1-1 score in a neighboring group. The winners of these games also qualify for the knock-out tournament. After these group stages, the tournament becomes a normal knock-out. The first round of the knock-out is played on Saturday, the remaining games on Sunday. The only thing that has changed over the years is the amount of time available. When I first played in the tournament in 1993, there was no byoyomi in the group stage. This has changed a couple of years ago. For this tournament, all Saturday games were played with 40 minutes and 40 seconds byoyomi for each player. For me this was quite a comfortable pace. My first game was against Fujimoto, the representative of Fukuoka. A very tough opponent, who made it to 1-kyu in the Shoreikai before giving up his dream of becoming a professional player. He is still very young at 26 and reached the semi-finals of the Amateur Ryu-O tournament last year. No real pressure in this game, I was expected to lose. Black: Grimbergen White: Fujimoto (Fukuoka) 11th Ama Ryu-O Tournament, Round 1, June 27th 1998 1.P7g-7f 2.P8c-8d 3.S7i-6h 4.P3c-3d 5.P6g-6f 6.S7a-6b 7.S3i-4h 8.P5c-5d 9.P5g-5f 10.S3a-4b 11.P4g-4f 12.G4a-3b 13.S4h-4g 14.K5a-4a 15.S6h-6g 16.G6a-5b 17.R2h-6h I have been playing the Yodofuribisha quite a lot recently, especially against stronger players. It is the ideal opening for players like me who like both Yagura and Furibisha but do not have the time to keep up with the latest opening developments. Pretend to play Yagura and once your opponent has chosen a Yagura position, then switch to the Furibisha. This takes a couple of extra moves, but the Ibisha side no longer can play the quick attacking variations, so in general this is not a big factor. The Ibisha side usually has to rearrange his pieces anyway, because the Yagura type castle is not well suited for defending against the Furibisha. I have heard that there are some nasty counter variations, but so far I have not encountered these. >From my experience, the Yodofuribisha gives good chances and this game does not show anything else. 18.P4c-4d I find 18.P6d to be more of a problem. In similar positions I have been badly beaten after 19.K4h P6e Px6e?? Bx8h+ Rx8h B*2h. This is one of the few opening traps in this strategy. 19.P3g-3f Played quickly to avoid 19.P3e. This would give white the opportunity to play a normal opening: the King's Head Vanguard Pawn. After S3c-S3d-G4c the position has become a normal Ibisha against Furibisha game. Since it is always good to keep a stronger opponent away from well-known book opening, I played 19.P3f. 20.G5b-4c 21.K5i-4h 22.K4a-3a 23.K4h-3h 24.B2b-3c 25.G6i-5h 26.K3a-2b 27.K3h-2h 28.L1a-1b I expected white to play anaguma. There is not much else to improve the position. 29.N2i-3g 30.K2b-1a 31.P6f-6e 32.P8d-8e 33.B8h-7g 34.S6b-5c 35.S6g-6f 36.S4b-3a 37.S4g-3h Played after long thought. Tempting was 37.P5e 38.Px5e 39.P4e to attack before the white anaguma is completed, using the pressure of the black bishop on 7g. I was not convinced by the power of the black attack after 40.B2d R7h (giving up the rook with the hanging gold on 4i seems too dangerous) Px4e Nx4e S4d Sx5e Sx5e Bx5e P*4d. White threatens to catch the knight on 4e after G5d, while 6i, 5g and 4f are also weaknesses. I decided to strengthen my position first. 38.S3a-2b 39.G5h-4g 40.P7c-7d 41.P5f-5e 42.P5dx5e 43.R6h-5h 44.B3c-2d 45.P2g-2f The bishop on 2d indirectly defends against the black attack (P4e B7i+). Before attacking, the bishop has to be chased away. 46.N8a-7c 47.P2f-2e 48.B2d-3c 49.P4f-4e I felt very good about my position here. Al my pieces are looking good and the attack looks solid. The only problem is the weakness on the head of the black king. Unfortunately there is no time for S2g-G3h: 49.S2g P8f Px8f S5d and after Sx5e Sx6e or R6h P7e (Px7e P*7f; Sx7e Nx6e), black is in trouble. 50.P8e-8f 51.P8gx8f 52.S5c-5d 53.P7f-7e I was wondering how Fujimoto would defend against this. I expected 54.R8d after which I was not completely sure how to continue. After the natural 55.Sx5e, white has the nasty counter 56.P*5g (Rx5g or R6h are answered by Nx6e). The black attack is not easy and the waiting move 55.R6h might be best. 54.P7dx7e? A big surprise and I think this is a mistake. White wants to play actively, but has not calculated this well. 55.P*7d 56.N7cx6e 57.S6fx6e After the game Fujimoto said he had hardly looked at this move, which I find incredible. Black now gets the chance to develop all his pieces. 58.S5dx6e 59.P7d-7c+ 60.P7e-7f 61.+P7cx8b I think this is better than 61.B5i R8d and black has trouble activating his pieces. 62.P7fx7g+ 63.R5hx5e Now black is clearly better. 64.S6e-5d After 64.S*5d Rx6e Sx6e R*7b black has a strong attack, since white can not defend with S*3a like in the game. After G4c-4b, P3e looks very strong. Also G3a +Px9a, threatening Px4d or P2d looks strong. 65.R5ex5d? Too eager. The following sequence looks very good, but giving up the rook gives white too many counter chances. Much better is 65.R7e and promotion of the rook can not be avoided. There does not seem to be any white counterattack anywhere. 66.G4cx5d 67.N*4f 68.G5d-5c 69.R*7b 70.S*3a 71.N4fx3d This was the position I was aiming for when I played 65.Rx5d. The gold on 5c is hanging, the bishop on 3c is as good as dead and white only has bishop and rook to attack with. Now I only need time to play S*4a... 72.B*9d! Useless move, I thought. Fujimoto shows his strength by building a strong attack out of nothing. After the game he told me that he was confident that he would win from here. 73.R7b-6b+ 74.B9dx4i+! Completely unexpected. The white attack suddenly goes from 0 to 100 miles an hour... 75.S3hx4i 76.R*7i 77.S*3h Played with great sadness. This was the silver I wanted to drop on 4a. Maybe 77.B*3h is better, but I could not bring myself to voluntarily lock up the bishop. Of course 77.S3h or G4h are too dangerous after Rx8i+. 78.R7ix8i+ 79.B*9h? Too aggressive. The lance I force white to take comes back to haunt me on the weakness that has been a concern all game: the head of the king. It was time to switch back to defense by 79.+Rx5c +Rx9i Nx2b+ Sx2b P*5i. The position then becomes very complicated. For example, after +P6h S*4h L*2f G*2g Lx2g+ Sx2g N*1e S3h the white attack also seems far from easy, with black ready to counter with moves like L*3d. I had almost used my 40 minutes here. 80.+R8ix9i 81.B9hx3b+ 82.S3ax3b 83.+R6bx3b 84.B*7f! Another great bishop drop I missed in byoyomi. I thought I could still make something out of it after 84.G*3a Nx2b+ Gx2b +Rx3c, but this bishop that both attacks and defends ends my hopes of winning this game. 85.N3dx2b+ 86.B3cx2b 87.S*4a Last desperate attempt. Now there is still hope after 88.Bx3b? Sx3b+ or 88.Bx4i?? +Rx2a. Of course this is not how it went... 88.L*2f 89.S*2g 90.+R9ix4i 91.S3hx4i 92.L2fx2g+ 93.K2hx2g 94.B7fx4i+ 95.L*3h 96.S*3a First my castle is blown away and then a cool defense. Game over. 97.+R3bx2c 98.S*1d Safety first. This move again defends and attacks. The rest is no problem. 99.P2e-2d 100.G*3c 101.+R2cx3c 102.B2bx3c 103.G*2c 104.R*2i 105.G*2h 106.N*1e Resigns The second round ---------------- I was not too unhappy about the first round. Of course, I had missed the chance of a major upset, but overall I played pretty well. In the second round came my big chance. As expected, I had to play the representative of Okinawa. Okinawa is a small group of islands south-west of the Japanese main coast. It is more famous for its pop groups than for its shogi players and I doubt that there are more active Shogi players than in Europe. I am not sure if a player from Okinawa has ever won a game in the amateur Ryu-O tournament, but before the game the chances seemed pretty even. I was not the outright favorite, since 25-year old Yamanoha had just returned to his native Okinawa after spending his student years at the university of Osaka. Clearly, he had been playing a lot of shogi there. Black: Grimbergen White: Yamanoha (Okinawa) 11th Ama Ryu-O Tournament, Round 2, June 27th 1998 1.P7g-7f 2.P3c-3d 3.P6g-6f 4.S7a-6b 5.S7i-6h 6.P6c-6d 7.G6i-7h 8.S6b-6c 9.G4i-5h 10.G4a-3b 11.S3i-4h 12.K5a-4a 13.K5i-6i 14.G6a-5b 15.P5g-5f 16.P7c-7d 17.G5h-6g 18.B2b-3c 19.P2g-2f 20.S3a-2b 21.S6h-7g 22.B3c-5a 23.B8h-7i 24.S2b-3c 25.P3g-3f 26.B5a-8d An unusual variation. White is aiming everything he has on 6f, but with the added option of building a normal Yagura castle. This would not be possible after the normal quick attack with the bishop on 2b. The disadvantage is of course that getting the bishop here has taken a lot of time. During the game I feared 26.B7c more, with serious pressure on the diagonal. 27.P3f-3e This pawn exchange brings the black bishop on 7i into play. Also, the square 3d is the weak point of white's position as long as the gold is still on 5b. 28.P3dx3e 29.B7ix3e 30.N8a-7c 31.B3e-4f 32.R8b-6b 33.K6i-7i 34.K4a-3a 35.K7i-8h 36.P4c-4d White likes to play 36.S5d, but after 37.P5e S4e B5g the silver on 4e is not looking good for attacking. Black threatens P4f S4e-3d S4g with a prefect piece shape. It is unclear what white can do to prevent that. 37.R2h-3h 38.P9c-9d Again white has the same problem after S5d P5e S4e B5g. He has the option of playing S4c instead of S4e, but that again does not give him much hope of attack. The waiting move 38.P9d indicates that black has won the opening battle. 39.S4h-3g?! A difficult decision. The obvious thing would have been to let white make a decision after 29.P9f. However, I wanted to keep the later attack P9e Px9e P*9g Lx9g N8e out of the position. Also, I want to have the silver on 3f for my own attack before white can complete his Yagura castle. If I could get the position S3f-N3g I was sure I could attack strongly. I had seen white's answer, but did not think it was a very strong move. 40.P4d-4e!? With hindsight I think white had no choice. It is the only chance to make his attacking formation work. It does give some extra weaknesses near the white king, but that could not be avoided. I was not impressed and expected things to get easier after this. That was a misjudgment. 41.B4f-5g 42.S6c-5d 43.S3g-3f 44.P6d-6e 45.N2i-3g 46.P*3e! I had completely overlooked this move. Yamanoha also thought about 46.P4f (Px4f P*3e Sx3e Px6f Bx6f Bx6f Sx6f B*4g is good for white), but after 47.Bx4f Px6f G6h-6h, we could not find any good continuation for white. The bishop on 4f is enough to stop the white attack. Black always has the combination P*6c-P*6d to close out the white rook. 47.S3fx4e No choice. Of course 47.S2g is no option and after 37.Sx3e Px6f Bx6f Bx6f Sx6f P*3d black loses the silver. Fortunately, Sx4e is not bad. 48.P6ex6f 49.B5gx6f 50.B8dx6f 51.S7gx6f 52.B*2g 53.R3h-2h 54.B2g-4i+ 55.P*3d 56.S3c-4b 57.S4ex5d 58.P5cx5d 59.P*6c? So far everything is forced. White has promoted his bishop, but black has good counter chances with the pawn on 3d. 49.P*6c is based on a stupid miscalculation. I though I could both promote my bishop and displace the white rook. The simple 59.B*4d is better. 60.R6bx6c 61.B*8a 62.R6c-4c! Of course. Strangely enough, I thought that white had to defend the pawn on 5d. After 62.R5c N4e R4c Bx5d+ black would have a very good position. However, after 62.R4c the black pawn on 4g hangs. Worse, after promotion the gold on 6g is also attacked twice. I have to defend against Rx4g+. 63.S*4e Sad to use the silver here, but I have no choice. 64.P*6c? In this game 6c is a mine. Every pawn dropped on this square explodes in your face. The two biggest mistakes in the game are pawn drops on 6c. Much better is 64.S*5c B7b+ G6b and after +Bx8c white wins the silver with P*4d. 65.B8a-7b+ 66.P3e-3f 67.S4ex3f 68.P6c-6d 69.P*6c?! Because of the earlier experiences in this game with P*6c, I am inclined to call this a mistake as well. It draws away the gold on 5b from the king, but after the simple 69.+Bx5d the white horse would have been well-placed for both attack and defense. After 69.P*6c white gets another attacking chance, but black just seems to be able to survive this. I think 69.P*6c is good enough, but 69.+Bx5d would have been more safe. 70.G5bx6c 71.+B7b-6a 72.P6d-6e 73.S6f-7g 74.S*6f 75.P*6h 76.N7c-8e 77.S7g-8f 78.S6fx6g+ 79.P6hx6g 80.P6e-6f 81.+B6ax4c Just before entering byoyomi I have time to calculate that I might just be in time to defend. 82.S4bx4c 83.R*6a 84.P*4a I think 84.B*4a Px6f +Bx7f Sx8e +Bx8e N*3c is also winning for black. Still, this might be better than the game. 85.R6ax6c+ 86.P6fx6g+ 87.G7hx6g 88.P*6f 89.+R6cx6f 90.B*3i 91.S*3c! If two pieces are simultaneously attacked, do not defend. It is time to go all out attacking. 92.N2ax3c 93.P3dx3c+ 94.B3ix6f+ 95.G6gx6f White has forced this gold away from the attack of the horse on 4i. Also, the rook on 2h is working well in defense. White has a lot of material, but the attack is very difficult, especially in byoyomi. I think black is winning here. 96.G3bx3c 97.N3g-4e 98.P*3b 99.N4ex3c+ 100.P3bx3c 101.P*3d! Looks slow, but I think this is the right move. White can not make consecutive mating threats and if he allows Px3c+, black is certain of victory. 102.P*6g 103.B*6d! Closes an escape route of the king. If white drops a gold or silver on 4b, white has no chance of mating and Px3c+ is decisive. 104.P4a-4b 105.P*6i! I am very happy with my endgame play in byoyomi. White threatened mate after S*7i: a) Kx7i G*6h Rx6h Px6h+ Kx6h R*5h or b) K9h G*8h Rx8h Sx8h+ Kx8h R*7h Kx7h R*4h. After 105.P*6i white has no mating threats anymore. 106.R*5h Suicide. This rook is exactly the piece I need. However, white has no defense. After 106.G*3b Px3c+ Gx3c N*4e, black wins. 107.R2hx5h 108.+B4ix5h 109.G*2b The pleasure of a full 40 seconds of byoyomi. After 103.B*6d P4b I already knew I needed a rook for a direct mate. With 40 seconds byoyomi I could verify all variations three times. 110.K3ax2b 111.P3dx3c+ 112.K2bx3c 113.N*4e 114.K3c-3b 115.G*3c Resigns Not a brilliant game, but after the Chinese Cho in 1994 this was only the second victory of a non-Japanese player in the amateur Ryu-O tournament. In my optimism after this win, I dreamed of becoming the first non-Japanese player to reach the knock-out tournament. This idea lasted about 5 minutes. Then I was told by Oda that my next opponent would be Watanabe Kenya, the tournament winner of 1997. The third round --------------- I can not really complain about an unlucky draw after getting the opportunity to play one of the weaker players in the tournament. However, having to play one of the strongest players in Japan in the tie-breaker is not really my idea of breezing through the tournament. This was going to be tough. A good omen though, the pawn toss gave me black for the third consecutive game. Black: Grimbergen White: Watanabe (Zen Ama Ryu-O) 11th Ama Ryu-O Tournament, Round 3, June 27th 1998 1.P7g-7f 2.P3c-3d 3.P6g-6f 4.P4c-4d Strange opening, but when you are strong, there is a lot that can be played. 5.S7i-7h 6.S3a-4b 7.S7h-6g 8.S4b-4c 9.B8h-7g 10.P3d-3e 11.R2h-8h This will be an Ai-Furibisha game, I thought. 12.P5c-5d 13.P5g-5f 14.S7a-6b 15.G6i-5h 16.P4d-4e 17.P6f-6e?! This badly timed pawn push already indicates that my concentration is lacking in this game. It would have been much better to play this one move earlier. I thought that white could not easily exchange bishops here because of the many holes in the position where black might drop a bishop. Don't think, calculate! 18.B2bx7g+ 19.N8ix7g 20.S6b-5c 21.K5i-4h This point in the game illustrates the difference in assessment between me and my opponent. I spent more than five minutes on this move because I was afraid of 21.P3f Px3f B*7i R8i B2d+. Finally, I concluded that the extra pawn and the extra moves were worth the promotion of the bishop. Watanabe was surprised that I had taken so long to come to the same conclusion he had reached instantly. 22.K5a-4b 23.K4h-3h 23.B*2b B*4d Bx4d+ S5cx4d B*2b B*3c Bx3c+ Kx3c only helps white. 24.K4b-3b 25.K3h-2h 26.G4a-4b 27.S3i-3h Watanabe suggested to play Anaguma here, so that black has a stronger defense against the wall of pawns white has built. I do not like the Anaguma very much (actually I think it is an opening for cowards), but in this case he might have a point. 28.P1c-1d 29.P1g-1f 30.B*2b 31.B*6h?! Better is 31.G6h. I was afraid for the pressure of the bishop on 2b and for the potential threat of S*7i, but after R8i both problems would be solved and black keeps the bishop in hand. 32.G6a-5b 33.R8h-8i 34.S4c-3d 35.L9i-9h 36.G5b-4c 37.P8g-8f 38.P2c-2d 39.P7f-7e 40.P2d-2e 41.P8f-8e 42.P5d-5e 43.R8i-8f 44.P5ex5f 45.S6gx5f 46.S5c-4d 47.P7e-7d? Despite the small inaccuracies, black does not have a bad position at all. However, 47.P7d is too impatient. White can play this attacking plan whenever he wants, so it is better to play 47.S6g first as will become clear later. 48.P7cx7d 49.P6e-6d? Too subtle. By creating a hole on 6c, I thought I would get good dropping threats when the rook would move to 5b. This never is an issue and P6d ends up helping only white. 50.P6cx6d 51.P*7b And after Rx7b P8d or P7a+ after any other move I have a good position, I thought. 52.P7d-7e! This counter I did not see. With the silver on 6g, this attack on the head of the knight would not have been a problem. 53.P7b-7a+ 54.N8a-7c 55.P8e-8d 56.P8cx8d 57.+P7a-7b 58.R8bx7b 59.R8fx8d 60.P7e-7f Black promotes the rook, but at the cost of a knight and a pile of pawns. 61.R8d-8c+ 62.R7b-5b And now also the silver on 5f is attacked. If this had only been on 6g... 63.P*5g 64.P7fx7g+ 65.B6hx7g 66.R5b-5c 67.B7g-9e Black's position does not look that bad, but the loss of the knight is a big problem. Together with the number of pawns in hand and the massive pawns at 6e-7e-8e white has a lot of attacking possibilities. Probably white already has the upper hand here. 68.P3e-3f 69.P3gx3f 70.N*2d 71.K2h-3i! The only defense. For example 71.Bx7c+? Nx3f K1h (K3g/3i Rx7c +Rx7c B*2h and mate) P1e and black is helpless against the white attack. 72.N2dx3f 73.P*3g 74.P9c-9d 75.B9e-5i 76.R5cx5f 77.P3gx3f 78.R5f-5c Black has dodged the first bullet. However, now the material deficit is a silver instead of a knight. 79.+R8c-8a 80.N7c-6e 81.B5i-4h? The last chance to make a game out of it is missed here. After 81.N*2d K2c +Rx2a white has to be careful, even though his attack is much easier than black's. 82.B2b-1c Attacks the weak point 5g and defends against N*2d. From now on I can only watch in admiration. 83.+R8ax9a 84.P2e-2f 85.P2gx2f 86.P*2g 87.S3hx2g 88.P4e-4f 89.P4gx4f 90.B1cx4f 91.N*3g 92.P*4a Decisive. This makes white's position completely safe. 93.L*5i 94.P*2e 95.G5h-4g 96.B4f-5e 97.P5g-5f 98.B5e-9i+ 99.P2fx2e 100.P*2f 101.S2gx2f 102.P*2g 103.G4i-3h 104.+B9ix9h 105.G3hx2g 106.L*5h 107.L5ix5h 108.+B9h-7f 109.P*4e 110.S4d-3c 111.P3f-3e 112.S3d-2c 113.P2e-2d 114.S3cx2d 115.S2f-2e 116.+B7fx5h 117.S2ex2d 118.S2cx2d 119.S*3h 120.L*4f 121.G4gx4f 122.+B5hx4h Resigns Also in this game I had some chances in the middle game, but shogi again proved too difficult for me. The Final --------- Neither of my first round opponents made a big impact in this tournament. Both went out in the first round of the knock-out stage. This year the final was between two times amateur Meijin Hayasaki (24) from Oita and 21-year old Hayashi from Shizuoka. Hayasaki won this battle of the young amateur stars and added the Ryu-O crown to his already very impressive number of amateur titles. To compare the top level with the level of the games above, here is the final: Black: Hayasaki (Oita) White: Hayashi (Shizuoka) 11th Amateur Ryu-O Tournament, Final, June 28th 1998 1.P7g-7f 2.P3c-3d 3.P2g-2f 4.P8c-8d 5.P2f-2e 6.P8d-8e 7.G6i-7h 8.G4a-3b 9.P2e-2d 10.P2cx2d 11.R2hx2d 12.P8e-8f 13.P8gx8f 14.R8bx8f 15.R2dx3d 16.B2b-3c 17.K5i-5h 18.K5a-5b 19.G4i-3h 20.G6a-7b 21.S3i-4h 22.R8fx7f 23.R3d-8d 24.P*8c 25.B8hx3c+ 26.N2ax3c 27.R8d-2d 28.S3a-2b Looks dangerous. After more than 10 minutes thought, Hayasaki decides to go for it. 29.B*2a 30.S2b-2c 31.B2ax3b+ 32.S2cx2d 33.G*4b 34.K5b-6b 35.+B3b-4a? Better is 35.+Bx4c (threatening mate and the rook) Rx7h+ Sx7h P7d +B8g with better play for black. 36.G7b-8b 37.G4b-5b 38.K6b-7b 39.+B4a-5a 40.P6c-6d 41.+B5a-6a 42.K7b-6c 43.G5b-4b 44.R7fx7h+ 45.S7ix7h 46.R*7i 47.+B6a-5b 48.K6c-7b 49.+B5b-9f 50.B*7d 51.+B9f-8g 52.R7ix2i+ 53.G3h-3i 54.+R2ix1i 55.R*2b 56.P*3h? Big mistake. If white plays 56.P8d to make an escape route for the king, things become very complicated. 57.G4b-5a 58.S7a-6b 59.+B8gx4c 60.G*7a 61.R2bx2d+ 62.S6bx5a 63.G3i-2i 64.L*4a 65.+B4cx3c 66.S5a-4b 67.+B3c-4d 68.+R1ix2i 69.+R2dx2i 70.P3h-3i+ 71.+R2ix3i 72.G7a-6b 73.P*7e 74.S4b-5a 75.P7ex7d 76.L4ax4d 77.N*5f 78.L4dx4g+ 79.S4hx4g 80.N*5e 81.N5fx6d 82.K7b-7a 83.S4g-5f 84.G*6e 85.S5fx5e 86.P*6c 87.B*3c 88.G*4a 89.L*4g 90.P*4b 91.P7dx7c+ 92.G8bx7c 93.P*7b 94.G7cx7b 95.N6dx7b+ 96.G6bx7b 97.P*7c 98.G7bx7c 99.N*8e 100.G7c-7d 101.P*8d 102.K7a-7b 103.P*7c 104.N8ax7c 105.S*8a 106.K7bx8a 107.P8dx8c+ Resigns
