Computer shogi was first developed by the author and the research group in late 1974. It has been steadily improved by researchers and the commercial programmers using some game-tree making and pruning methods, opening and middle game databases, and feedback from research into tsume-shogi (mating) problems. Now, it has already reached stronger four-dan level. In this paper, the author discusses contemporary computer shogi, especially how the programs behaved at the 13th World Computer Shogi Championship, where 60 teams applied and 45 teams entered, in March, 2003.
