(This is an Android small game -- interactive human-computer game gobang. The reason why it is called interactive human-computer game gobang is that before entering the human-computer game mode, you can set the opening at will. Together, in the game process, you can see the machine's consideration process, and also identify the advantages and disadvantages of each placement point. I hope students who like renju can like it. Together, it is also very suitable for entry-level practice.)
