AMERICAN GO ASSOCIATION ARCHIVE GAME AND FUSEKI INDEX BY FUSEKI
FUSEKI INDEX
February 1972
Craig R Hutchinson, crhutch@erols.com
The index stone order is BWBW.
The index corner location order, if the corners are lettered clockwise ACDB, is: Parallel-ABCD, Diagonal-ABDC.
Corner placements are indicated by number with number 1 at Star (4,4), 2 at San San (3,3), 3 & 4 at Komoku (3,4),
5 & 6 at Takamoku (5,4), and 7 & 8 at Mokuhazushi (5,3). The Board below shows the Index Order and Corner Numbers
The total number of parallel and diagonal placements is 2*84 = 8192.
The total can be reduced by more than half with consideration of respective rotation symmetries
(e.g. R:A-B is a rotation about the A-B axis).
The parallel index is the default. Tags are used for further indexing; e.g. the Shusaku opening is indexed
with a "U" tag as 3831U where black follows with an approach at 3 against the 8 in the B corner.
The following tables lists some example parallel and diagonal indexes with rotation equivalents.
An index of games that includes the American Go Journal, American Go Newsletter, Go Review, and Go World is at GAME INDEX
