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.

Better is probably 28.Nx4e Nx4e~Px4e Bx2b+ Kx2b P3e and now white has the counter B*3g Sx4e Bx4h+ Gx4h R*3i~K8h Rx3e+ and black is in trouble.~} P3f-3e P3dx3e N3gx4e N3cx4e B7gx2b+ G3bx2b P'4d S5cx4d {After 36.N3g+ Px4c+ +Nx4h +Px5c black is clearly better.~} S5fx4e S4dx4e R4hx4e P'4d R4ex3e P'3d R3e-6e {Morishita did not see this move long enough in advance.~} N'6d {Can't be helped, but white would have liked to use this piece somewhere else.~Also, the gold on 2b is painful.~} P'4e P4dx4e B'7a R8b-7b B7a-2f+ S'3e +B2f-3g P4e-4f N'7e {Great attacking move.
