Our overall goal is to study the use of information by Go players and the structure of their Go knowledge. In particular, in this paper we focus on human memory, and conclude with a discussion of the bene ts of modelling human memory to AI and Go programs. We report on two memory experiments. The rst experiment used Japanese Go players to replicate earlier studies on Australian Go players. The second experiment consists of three case studies of master Go players (6 to 8 dan amateurs). The general task in the experiments was to reconstruct Go positions stone by stone in correct game order. T...
