From: Richard Sams parkcity ne jp> Date: 22 mar 2007 Subject: Re: Watanabe's comments (2) Akira Watanabe is very impressive. After winning his game against=20 Bonanza under great pressure, I imagine he had to attend the inevitable=20 sponsor=92s party and answer a lot of questions from people not=20 necessarily familiar with shogi. According to his blog, he got home at=20 midnight. He must have been exhausted, but instead of going to bed he=20 started writing his report on the game for his readers. At around 2.15=20 a.m. I noticed that he had already posted the first part (Preparations=20 for the Game). Since it was quite short, I decided to translate it,=20 assuming he would write his report on the game after a good night=92s=20 sleep. But when I finished my translation at around 3.00 a.m. I noticed=20 that he had already posted his game report! I=92ve just finished=20 translating that (see below). Now I notice that he=92s at it again,=20 answering questions from fans about the game.

We had the following conversation=20 in the car: NHK photographer: =93Bonanza has already been set up at the venue and=20 lost a game to Matsuo.=94 Me: =93You=92re kidding! You mean that Matsuo?=94 =93Yes.=94 =93Matsuo 6-dan lost to Bonanza?=94 =93Oh no, sorry, it wasn=92t Matsuo =96 it was Matsumoto-san (amateur 4 or = 5=20 dan) who=92s in charge of the Internet live transmission.=94 =93Ah, well that=92s not so surprising.=94 (Here I am feeling really nervou= s=20 before the big game and he=92s trying to give me a heart attack!) =A0Matsumoto-san, who calls Bonanza =93my friend,=94 phoned me on the day= =20 before the game: =93Hello. Just to let you know that Bonanza is already=20 at the venue and can apparently analyze many more moves ahead than=20 before. (Sounding really pleased) Bonanza=92s rating is now 2800! Good=20 luck!=94 Who is this guy supporting? By the way, shogi ratings are provided on the Shogi Club 24 Internet=20 shogi dojo. The highest rating at the moment is 3084, so that means=20 Bonanza is only 300 points below the top. This is no joke =96 I=92m=20 beginning to get scared. We arrive at the venue. Judging from what people there say, it really=20 seems true that today Bonanza is functioning very well and fast too. I=20 was quite shocked. Returning to the back room, I try to relax but my=20 heart is beating faster and I=92m already in slight panic mode. If I=20 think about the coming game I=92ll only have negative thoughts so I spend= =20 the remaining time watching TV. The game begins. As expected, Bonanza plays 4th file rook anaguma. =A0GAME DIAGRAM (after 30 =85 L-1b) Up to now everything has gone as expected. I looked at various ways of=20 playing this position and came to the conclusion that this was the=20 safest. Here Bonanza usually plays P-6e S-5c; Bx3c+ G3bx3c; B*7a. REFERENCE DIAGRAM After =85 R-7b, Black has to exchange the bishop for the silver on 5c and= =20 White already has a winning position. This is what I had been expecting=20 but today Bonanza didn=92t play this way. Afterwards I asked the=20 programmer, who said that Bonanza had looked at B*7a but stopped=20 thinking at that point! Because it didn=92t play B*7a I felt =93there=92s something different about= =20 Bonanza today.=94 GAME DIAGRAM (after 47. P-6e) P-6e seemed to be a surprise for many people, but having played Bonanza=20 many times, I was expecting it. This kind of move is generally=20 considered bad, but in practice it=92s not so easy to punish. 51. B*6f was a move I=92d never seen before in such a position, but it=20 was actually quite good. It=92s the kind of move that shogi pros don=92t= =20 consider, and you could even say that computers have contributed to=20 improving the technical level of shogi in this way. I think computers=20 will continue to show us new kinds of move like this and that this=20 could lead to the discovery of new ideas and tesuji. GAME DAIGRAM (after 70 =85 *Rx9i) This is a key moment. Here Bonanza played 71. P-6d. When I saw this=20 move, I said out loud =93What=92s this (what=92s this weak move)?=94 P-6d c= uts=20 off Black=92s promoted bishop on 9a and even if he makes a tokin with=20 Px6c+, it=92s a long way from my anaguma castle. Thinking =93Thanks very= =20 much!=94, I sank into deep thought. Several minutes later I was thinking =93Maybe P-6d is a good move after=20 all.=94 If I play =85 Px6d, he takes my knight with *Bx8a and, compared to= =20 taking the knight immediately in the diagram position, his attack is=20 one move faster because he can bring the promoted bishop back with=20 *Bx5d. So I can=92t take the pawn on 6d. If I can=92t take the pawn, I must= =20 attack right away but I can=92t see any effective way of attacking. After= =20 the move I played, =85 S-3e, I was expecting Px6c+, when I intended =85=20 P-2e with a clear advantage. I had invited this knowing very well that=20 the computer program awards high points for making a tokin, but Bonanza=20 immediately played the best move, P-3f. Bonanza had chosen P-6d based on the thinking =93After P-6d the opponent= =20 must attack. If so, the attack can be successfully repulsed.=94 Human=20 players wouldn=92t consider P-6d because of their intuitive fear of=20 blocking the promoted bishop=92s diagonal. Seeing these moves, I realized that I my opponent was much stronger=20 than the Bonanza I had encountered up to then. GAME DIAGRAM (after 88 =85 G*1e) This was the point where the outcome was decided. Just when I had=20 worked out that I would win after 89. P*2d, Bonanza actually played it. If my opponent were human, I=92d think =93he=92s probably missed *Rx3i=94 b= ut=20 since I trust Bonanza=92s endgame ability I was now thinking =93*Rx3i ought= =20 to win, but maybe there=92s an amazing reply =85=94 In the same position you think differently depending on whether the=20 opponent is human or a computer. In fact, it seems that Bonanza underestimated =85 *Rx3i. Computers miss=20 things too. I thought the computer=92s endgame was perfect, so I felt a=20 little relieved! After =85 G*5a, instead of P*2d, I had been afraid of the line L*2g Gx2f;= =20 Lx2f P*2g; G*3h Px2h*; *Bx2h (Reference Diagram). REFERENCE DIAGRAM (up to 95. *Bx2h) To play this, the opponent has to think =93I=92m giving up a rook and my= =20 silver will be taken by a pawn, but I=92ll be able to bring my promoted=20 bishop into the defense and my opponent has run out of pawns.=94 I=20 figured that Bonanza wouldn=92t be capable of finding such a high-level=20 sequence. So P*2d was the losing move. Not surprisingly, the intuitive =93sense of= =20 distance=94 from the king seems to have been hard for Bonanza. Still, I=92m glad I won. I=92m really relieved too. I had heard that computer programs will get stronger using=20 high-performance hardware, but I didn=92t expect it to be as strong as=20 this. With further advances in the hardware and improvements by the=20 developers, they are going to get even stronger. I thought they still=20 had quite a way to go, but now we have to recognize that they=92ve=20 reached the point where they are getting to be a match for=20 professionals. I think we can no longer avoid matches between computers=20 and shogi professionals. And next time it will attract even greater=20 attention. For the past month, I=92ve been feeling quite a lot pressure as the big=20 day approached. Now at last I=92m free from that pressure, so I=92m going= =20 to sleep very well .. zzzzz =A0 =A0 =A0 --^---------------------------------------------------------------- This email was sent to: = shogi-l shogi net EASY UNSUBSCRIBE click here: http://topica.com/u/?a2i6Ys.= aB5TiY.= 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 --^----------------------------------------------------------------
