Statistics of Professionals' Openings

This is a part of the statistical data of professinals' openings on Shogi Yearbooks. The original data contains figures for each move from the initial position to the fourth moves (White's second moves). Here shows a comparison of the figures after the fourth moves. The data of FY 1997 are from the search of Shogi Yearbook CD-ROM, because there is no data on the book in FY 1997.


[Complete Version] The figures in parentheses are for the comparison with other years. Dashes mean that the number of the games is less than 30 (FY 1996-2001) or 35 (FY 2002, 2003 and 2005) or 40 (FY 2006-2008) or 50 (FY 2004).
