Frank A. de Groot just announced that he will continue the development of Moyo Go Studio at Godiscussions.com. These are wonderful news for the Go community.
In fact, I’ve just realised that, there has been a whole “revolution” during the lasts months when we talk about Go study programs.
Till a few months ago, there were only a few “serious” programs for studying Go. Many Faces of Go could be discarded as a proper studying tool due to his lack of database handling and pattern search, though it is very famous because most users started playing computer-go with Igowin. Moyo Go Studio and SmartGo were the main programs for serious students.
Then, Stonebase appeared on the scene: an asian program with very good database handling but some weak points. The developer of Drago got into serious programming sessions and started publishing new versions, including Kombilo’s engine in it; now Drago is another serious competitor for the previous programs.
Since the lack of spare time prevents me from making proper reviews, you’ll have to try them by yourself. Go, get them and compare!
