From: tiger22 IX NETCOM COM Date: 6 apr 1999 Subject: Analysis I enjoy very much playing shogi on the Java Shogi server now located at http://www2.patt.co.jp/~ryo/index-e.html for the English version. I wonder if many shogi-L members play there. Sometimes I play interesting games there and capture the moves from the history file. I try to analyze the game afterward to see if I can spot recurring errors in my play. But sometimes I can study for hours and overlook the simplest tactic. So, I expose the fruit of my analysis to the harsh reality of my critics on this list to see how polluted that fruit really is. Any comments are therefore expressly welcome. # ---- JavaShogi version 2.1.7 HistoryFile ---- # Ryo Neyama (ryo muraoka info waseda ac jp) # Compatible with Kifu for Windows95 V3.20 # Yoshikazu Kakinoki (PAF01611 niftyserve or jp) StartDate: 06-Apr-99 9:17:00 AM StopDate: 06-Apr-99 9:54:26 AM TeaiWari: Hirate BLACK: HiroshimaCarp WHITE: Randy Count----History 1 76Fu(77) 2 34Fu(33) 3 66Fu(67) 4 84Fu(83) 5 77Kaku(88) 6 42Gyoku(51) 7 68Hi(28) 8 62Gin(71) 9 48Gyoku(59) 10 32Gin(31) Preparing the left-side mino castle which is more solid than the boat castle, but takes longer to prepare. 11 38Gyoku(48) 12 31Gyoku(42) 13 28Gyoku(38) 14 52Kin(61) 15 18Kyo(19) While my opponent prepares anaguma castle, I can complete my own castle. 16 33Kaku(22) 17 19Gyoku(28) 18 24Fu(23) 19 28Gin(39) 20 22Gyoku(31) 21 58Kin(69) 22 23Gin(32) 23 38Kin(49) 24 32Kin(41) 25 48Kin(58) 26 44Fu(43) 27 96Fu(97) 28 94Fu(93) 29 65Fu(66) 30 43Kin(52) Both sides castling is complete. 31 64Fu(65) 32 DoFu(63) 33 DoHi(68) 34 63FuUtsu 35 69Hi(64) 36 85Fu(84) Black has gained a pawn in hand, but I spot an opportunity to attack on the 8-file. 37 78Gin(79) 38 45Fu(44) Offering the exchange of bishops when black cannot recapture with the silver because of B'78 forking rook and pawn. 39 65Hi(69) 40 77KakuNaru(33) 41 DoKei(89) 42 86Fu(85) 43 85Hi(65) The point of my opponent's 39th move is revealed. 44 DoHi(82) 45 DoKei(77) 46 87FuNaru(86) 47 DoGin(78) 48 89HiUtsu 49 82FuUtsu A surprise. Black abandons the silver and knight. 50 87HiNaru(89) 51 81FuNaru(82) 52 85Ryu(87) 53 91To(81) 9 8 7 6 5 4 3 2 1 +---------------------------+ White in hand: |b+P * * * * * * wN wL |a B S N P | * * * wS * * wG wK * |b | * * wP wP wP wG * wS wP |c |wP * * * * * wP wP * |d | * w+R * * * wP * * * |e |bP * bP * * * * * * |f | * * * * bP bP bP bP bP |g | * * * * * bG bG bS bL |h Black in hand: |bL * * * * * * bN bK |i R B N L P +---------------------------+ White to move. I thought I had the advantage here. I've won silver for lance and promoted my rook which has easy access to the enemy camp. However, my own camp has many places for the enemy rook and bishop to drop. Additionally, I did not have a clue as to the proper plan here. 54 51Gin(62) Probably B'33 was better to close the dangerously open diagonal as well providing cover for the silver to move to 51 as needed. 55 84FuUtsu A clever response taking advantage of a bishop drop fork if I carelessly capture this pawn. 56 33KakuUtsu 57 82HiUtsu During the game, I thought R'81 was stronger, tying the bishop to defense of the silver plus the 2a knight is defended only by the king. 58 99KakuNaru(33) Now, I have time to take this piece. 59 15KeiUtsu 60 42Gin(51) 61 41KakuUtsu 62 33Uma(99) "Retreat the uma for defense." "An uma is worth 3 generals." (Japanese proverbs). 63 23KeiNaru(15) 64 DoGyoku(22) 65 83FuNaru(84) 66 14Fu(13) Aiming for an attack along the 1-file, but with only 1 pawn in hand, it is an ill-conceived idea. 67 63KakuNaru(41) 68 65Ryu(85) 69 73To(83) I realized that the 1-file attack is too slow compared to this onrushing tokin. "A tokin is faster than you think." (Japanese proverb) 70 46Fu(45) Only 1 pawn in hand, but it is enough for this frontal assault. 71 DoFu(47) 72 47FuUtsu 73 DoKin(48) 74 35KeiUtsu The 2 knights in hand play the key role here attacking 47 and 27 from this square. 75 56GinUtsu 76 47KeiNaru(35) 77 DoGin(56) Probably neither player seriously considered variations taking the rook. 78 35KeiUtsu 79 36Uma(63) 80 68Ryu(65) 81 81HiNaru(82) 82 31KyoUtsu Now the back rank is easily defended. 83 26KyoUtsu 84 49GinUtsu 85 39Kin(38) 86 47KeiNaru(35) 87 DoUma(36) 88 38GinUtsu 89 DoKin(39) 90 DoGin=(49) 91 DoUma(47) 92 DoRyu(68) 93 39GinUtsu 94 68Ryu(38) 95 36KeiUtsu 96 47KakuUtsu 97 45KeiUtsu 98 38KinUtsu 99 33KeiNaru(45) It's probably not wise to give me a knight in hand while N'35 is still available to me. 100 DoGin(42) 101 38Gin(39) 102 DoKakuNaru(47) 103 39KinUtsu 104 35KeiUtsu 9 8 7 6 5 4 3 2 1 +---------------------------+ White in hand: |b+Pb+R * * * * wL wN wL |a G S | * * * * * * wG * * |b | * * b+P * wP wG wS wK * |c |wP * * * * * wP wP wP |d | * * * * * * wN * * |e |bP * bP * * bP bN bL * |f | * * * * bP * bP bP bP |g | * * * w+R * * w+BbS bL |h Black in hand: | * * * * * * bG bN bK |i B S Px4 +---------------------------+ Black to move. 105 41KakuUtsu A key defensive move in many variations, but it was absolutely necessary to capture the uma first. After Gx38, +Rx38, S'39, Nx27=, Sx27, the variations are exceedingly complex no matter what move I make here. Black's game is hanging by a thread, but it is really tough to crack it. For example, +Rx27, B'41, S'38, Bx32+, Lx32, G'28 provides stiff resistance. Sx39=, Gx27, S'38, R'28 (B'28 needs to be examined) Sx28+, Gx28, S'27, Gx27 Sx27+, S'39, G'38, S'28, R'48, Sx38, Rx38+, G'39, B'47, Gx38, Bx38+, is one possibility that seems decisive, but there are so many moves to consider. That the game was decided by a blunder is not a surprise. 106 27Kei=(35) 107 DoGin(28) 108 28KinUtsu 109 Resign
