Gnu Shogi Database (GSDB)

Browse hundreds of historical professional and amateur shogi games. Select a collection, pick a game, and replay it on the interactive board.

Kifu is a shogi game record. Every move is written down so the game can be replayed and studied later. Serious students of shogi build up - and work through - large libraries of kifu to understand openings, middlegame plans and yose (end-game) technique.

The Gnu Shogi Database (GSDB) is a collection of Japanese chess games and sample openings. Hundreds of shogi kifu (game records) have been documented. The orignal GSDB comes with an applet that allows viewing and manipulating of the collections. Unfortunately, the web browsing industry has discontinued support for Java applets. That makes browsing the collections trickier, without a little help.

For those techies interested in browsing the original GSDB 2.7.4 source code and license, you can download it here.

Just a note on shogi rankings: The lowest ranking is 15-kyu. The rankings go down to 1-kyu as the player improves. After 1-kyu, rankings begin counting up with 1-dan all the way up to 9-dan. Professional shogi players begin around 5-kyu and go up to 9-dan (the champion professional). Ameteurs of the same rank as professionals are typically less skilled than their professional counterparts.

[Name "Thomas Majewski"] [Email ""] [Country "Japan"] [Sente "Tanigawa"] [Gote "Sanada"] [Black_grade "Ryu-o"] [White_grade "Chall"] [Result "1-0"] [Comment "Kakugawari"] [Source "This week in shukan shogi"] [Event "10th Ryu-O sen"] [Date "19971029"] [Round "2"] [Venue ""] [Proam "Professional"] P7g-7f P8c-8d G6i-7h G4a-3b S7i-6h P3c-3d B8h-7g {In the first game of this match, it was kind of surprising to see Tanigawa~choose a Furibisha strategy. Since this is not his natural strategy, he was~expected to use it only if he would get a comfortable lead in the match. This~game's opening is no surprise, though. Tanigawa is a specialist in the~Kakugawari (Bishop Exchange) opening.~} P8d-8e S3i-3h S7a-7b P2g-2f B2bx7g+ S6hx7g S3a-4b P1g-1f P1c-1d P9g-9f P9c-9d P4g-4f P6c-6d S3h-4g S7b-6c K5i-6h G6a-5b S4g-5f S4b-3c G4i-5h K5a-4b K6h-7i S6c-5d P6g-6f P7c-7d P4f-4e {Aggresive, Tanigawa-like opening play. Since white has not played the 4d pawn,~black takes control of the center. White's position is very strong, though and~hard to break down.~} N8a-7c P3g-3f K4b-3a N2i-3g R8b-6b B'4f {Strong square to drop the bishop. It seems Sanada had nothing special against~Tanigawa's strategy and is forced into a waiting game (sakusen-make).~} R6b-6a K7i-8h L9a-9b {Criticized by Morishita, whi felt that immediately 21...S6c followed by P5d~would have been better.~} R2h-4h G5b-4b {All waiting moves by white. He can only be patient until black starts the~attack.~} L1i-1g {Tanigawa decides that attacking on the edge is more promising than attacking~through the center.~} S5d-6c {The sealed move and a subtle defense move. 23...K2b is not so good, because of~24.N2e S2d 25.S5e which favours black.~} S5f-4g {Another preparation move, this time to defend the head of the knight against~a later pawn drop on 3f.~} P5c-5d R4h-1h S3c-2d P2f-2e S2d-3c P1f-1e P1dx1e L1gx1e L1ax1e R1hx1e P'1c R1e-1i R6a-8a P'1b S3c-2b P3f-3e P3dx3e B4fx3e G4b-5b P4e-4d P4cx4d B3ex4d L'4b B4dx2b+ {Strong bishop sacrifice and the only way to continue the attack.~} K3ax2b {Better would have been 36...Gx2b. After 37.P1a+ Lx4g+ 38.Gx4g P8f 39.Sx8f B*5h the~position can go either way.~} P1b-1a+ K2bx1a P2e-2d {If Tanigawa would have played 38.P*3c Gx3c 39.P*1d Px1d 40.Rx1d P*1c 41.P*3d G3b 42.S*3c~Nx3c 43.Px3c+ Gx3c 44.L*3f he would have won quickly. "I should have looked at that~more carefully" -Tanigawa. Now Sanada gets chances to get back in the game.~} K1a-2b P2dx2c+ G3bx2c P'2d G2cx2d L'2h P'2c L2hx2d P2cx2d S'3d P'3c {Strong defense. After this, black is struggling to make his attack work.~} G'2c K2b-3a S3dx3c+ K3a-4a P'4c L4bx4c +S3cx4c G5bx4c P'4d G4cx4d L'4f K4a-5b L4fx4d B'5e {Great move, but at the wrong time. If white would have played 100.P8f first,~the outcome of the game would have been very doubtful after 51.Sx8f (Px8f~P*8e is very difficult to defend) B*5e 52.L4b+ Kx4b 53.N4e S*4d 54.R3i P*3h 55.Rx3h P*3g.~} L4d-4b+ K5b-6b {The difference with the variation above is that with the silver still~defending the pawn on 6f, black can win the bishop by P5f and wins, so~white can not take the lance here.~} S4g-4f {Great silver sacrifice adding decisive strength to black's attack.~} B5ex4f R1i-4i B4f-3e R4i-4c+ P8e-8f S7gx8f L'8d P'4d L8dx8f P8gx8f S'6i G'5c K6b-7a G5cx6c {It is close, but white has no mate and no defense.~} R8ax8f P'8g S6ix7h+ K8hx7h R8fx8g+ K7hx8g B'6i S'7h P'8f K8gx8f S'8e K8f-7g S8ex7f K7g-6h
