The following reflections are inspired by the work in the Swiss Museum of Games, where we are actually rearranging the permanent collection. The museum exists since 16 years now and is housed in a medieval castle at La Tour-de-Peilz situated directly at the shore of the Lake Geneva. The collection consists of about 4000 games from all over the world and from all times.

In this paper, we interpret the move decision of baduk by an economic point of view. We then build an economic theory approach to the baduk player's decision making process. We propose a hypothetical baduk valuation function(BVF) and impose such assumptions on the BVF that prevail in economic objective Junctions. From the BVF, we derive testable forms to estimate and test our theory. We also develop a 2-stage simulated estimation method to resolve the censored dependent variable problem arising from the resigned games. Through this, we can convert the win/lose series of the resigned games to the observable expected point gap series. The sample data are supportive of our theory. Parameter estimate of the number of total moves variable is significant in both the absolute point gap model and the mere point gap model, which verifies that the economic decision making theory can add some power to explaining the move decision mechanism of the baduk players. In addition, our regression model provides little evidence for the effect of the recent increase of dum on offsetting the first move advantage of the black player.

The system is based on fundamental game theory of the zero-sum games. It offers a ratio scale, starting with zero for the strongest play up to 80 for beginners. It was started in 1922 by Bruno Ruger in Dresden. And it was in common use before and after World-War II till to the mid 1970s. That was valid all over Europe at that time i.e. Germany, Austria, Yugoslavia, Netherlands, mainly. In addition to describe its historical origin, we want to show the important aspects that even now are of interest for us. Discussion about statistics shows the better quality of rating by ratio scaling against conventional ranking. The evaluation of tournament results proves the assumptions. Considerations are given about quantitative measuring of psychological behaviour.

This paper describes three software that are used to teach beginners the game of Go. Ponnuki plays the game of ponnuki-go which consists in capturing first a stone on a small board. It can be used with different sizes for the board and different configurations of play. FiveStones plays the game of capturing five stones, it is an intermediate game between ponnuki-go and the real game of Go. GoloisStrasbourg plays the game of Go on a 9x9 board. It counts the territory with the strasbourgeoise rule which simply consists in counting the stones present on the board at the end of the game. This rule is very easy to understand even for beginners, and GoloisStrasbourg enables beginners to learn Go by themselves, possibly without assistance. For the three software, the paper describes the methods used to implement them and some problems and solutions encountered in using them in practice.

In this paper, problems of the existing location marking system for the moves are pointed out and proposed a new system for structural reform (new formation) of the location mark and also discussed the necessity and characteristic of introducing this method. The newly introduced marking system in this article is corner coordinate method which takes four corners as the starting points. We carried out, to prove handiness of the new system, two experiments for comparing the existing system (19X19) with the review of a record of the game. In experiment 1, the speed of placing of the moves and accuracy between two systems, and we found that there was no difference. This shows that the new system is neither complicated nor difficult than the existing system. And in experiment 2, comparing the speed of the placing stones from reading a recorded game and the corner starting point system, the new system was faster in speed. This kind of result shows the convenience of the corner starting point system. Lastly, we have canvassed that utilization method of the corner starting point coordinate system and the need of international standardization of marking system.
