1 # Shogi Game 1 (amateur game, amateur comment): introductory game.
3 # Below you find (the English translation of) an annotated game which was
4 # published in the Dutch Shogi magazine "81" and in the Dutch beginners
5 # booklet. It has proven to be a very useful game to explain some basic
6 # principles of Shogi. Also, it is a rather straight forward game compared
7 # to professional games where in most cases very diffuse middle game fights

16 [ This move is necessary, otherwise white can exchange pawns: 3.P2d Px2d
17 4.Rx2d. He would thus get a pawn in hand and open up his rook file. ]
19 [ White closes the bishop diagonal again. He plans to play ranging rook
20 (the rook goes to 5, 4, 3 of 2b; a defensive strategy) and in that case
21 he'd better avoid an exchange of bishops. One of the reasons is that he
22 will have problems developing his pieces without leaving holes for
24 4.S4h R3b 5.P3f S4b 6.K6h K6b
25 [ In general the rook plays an important role in the attacks. It is wise
26 to move the king away from the area where the initial fights will be
27 and both players act according to the Shogi proverb "keep the rook and
29 7.K7h K7b 8.P5f P5d 9.G4i-5h G4a-5b
30 [ Both players use their second gold general to build their castle. ]
32 [ In itself this move is not bad. However, it will become clear that
33 black plans a quick attack and in that case it is wiser to omit this
36 [ The advance of the edge pawns must be timed very well. The remark at
37 black's tenth move applies here too: this move is good if black wants to
38 play a slow game, because it eliminates a future B1e. ]
39 12. P4f K8b 13.N3g S7b
40 [ Black develops his knight in order to start an attack over the second,
41 third and fourth files. White strengthens his king's position and awaits
42 the attack. He aims at a counter attack as soon as black has broken
43 through into the white camp. Probably white's breakthrough will take
44 place later, but he has good compensation in the form of a stronger
45 castle. This theme occurs very often in static rook versus ranging rook
48 [ Black starts his attack and white puts up a very passive defence. His
49 rook has a hard task now to penetrate the black position. Moreover, he
50 blocks his own bishop. It seems much better to start a counter attack
51 with 14... P3e, later to be followed by B2b, B5a or Bx4d in order to
52 use his rook more actively. ]
53 15.Px4d Sx4d 16.P*4e S5c
54 [ 16... Sx4e is more active. A silver general is normally more valuable
55 than a knight, but white gets two pawns in hand and black none, while
56 the knight might come in handy for white too. ]
57 17.Bx3c+ Nx3c 18.P2d Px2d
58 [ Black threatens to break through and white had to consider taking the
59 pawn on 2d or starting a counter attack with Nx4e. If he choses the
60 latter, black can play Px2c+ followed by +P3c. The disadvantage is the
61 black "tokin" (=promoted pawn) that white will get in his camp; the
62 advantage is that it will cost black two more moves to promote his
63 rook. Because white did not trust that the result after engaging in a
64 "semeai" (=mutual attack) with 18...N4e would to give a positive
65 result, he captured the pawn on 2d. Making the right decision in
66 moments like this often makes the difference between a win and a loss:
67 miss one attacking chance and you will be forced to defend the whole
68 game until the unavoidable defeat; on the other hand, an unsound attack
69 can destroy all "aji" (=potential, meaning possibilities, threats)
70 without getting anything in return. ]
71 19.Rx2d Nx4e 20.Nx4e Rx4e 21.R2a+ P*4g
72 [ Now it becomes clear why black's 10.S6h was not good. Had this move
73 been omitted, then white would not have had the time to play 13... S7b
74 and after R2a+ the gold on 6a would hang. Thus black would have kept
75 "sente" (=initiative). Instead of 21... P*4g B*6d is a very good move,
76 because after 22.P*2h black does not have a pawn in hand anymore and he
77 is being threatened with the annoying 22... N*4f 23.G5g N3h+ 24.S4g
78 +N4h also. Black can also counter 21... B*6d with 22.N*3g. White would
79 then reply with 22... R4b 23.B*3c P*4g 24.Bx4b+ Sx4b. The white rook
80 has played its role and instead of spending moves on saving it white
81 starts to scatter black*s defences by successive pawn drops on the
82 fourth file: 25.Gx4g P*4f 26.G5g N*6e 27.G5h P4g+ 28.Gx4g P*4f. This
83 analysis was provided by Kato Hifumi, 9-dan professional (the highest
84 regular grade). Destroying the coherence of the enemy pieces (their
85 shape) by dropping pawns is one of the most important Shogi techniques.
86 With the actual move 21... P*4g white missed a good chance. ]
87 22.Sx4g P*4f 23.B*3g Px4g+ 24.+Rx6a +Px3g
88 [ 23.B*3g seems pointless, but a closer look reveals that it is actually
89 quite mean. On move 24 white cannot capture blacks "Ryu" (=dragon
90 =promoted rook) with his silver: 24... Sx6a 25.N*7d K7b 26.G*8b mate.
91 By attacking the front of the white castle and threatening to mate him
92 there, black has the chance to break down the white defences from the
95 [ Here 25... B*4d would be much better, because it is defensive and
96 attacking at the same time. After e.g. 26.G*4c Bx9i+ 27.Gx5c black
97 threatens 28.+Rx7b Kx7b 29.S*6a K8b 30.S*7a Kx7a 31.G*7b mate. White
98 is one move quicker, however. He has the following beautiful "tsume"
99 (mating sequence where every move is check): 27... N*8f 28.Px8f S*8g
100 29.Kx8g B*9h 30.K7h Bx8i+ 31.K8g +b8i-8h 32.K9f L*9e mate. This
101 illustrates the sharpness of Shogi: one move can make the difference
102 between winning and losing. ]
104 [ This move eliminates white's last chances. 26... R4b 27.+Rx4b Sx4b
105 28.R*4a seems annoying, but after 28... B*3c 29.S7g B*3b white wins
106 the rook and with his "tokin" on 3g there still is some hope. ]
108 [ White cannot defend anymore, so he starts a desperate attack. Black
109 does not lose the right track, however. ]
110 28.Nx5c+ +Px5h 29.+Nx6b +Px6h 30.Gx6h N*8f 31.Px8f B*6i 32.Gx6i
111 R4h+ 33.N*6h +Rx6h 34.Gx6h S*8g 35.Kx8g N*9e 36.K7h Resigns
112 [ White resigns here, because after 36... B*8g 27.K7g his attack has
