Suntown: Renju for baby champions league play online

Renju is a board game, which originates from Japan.
It is a game played on a Go board of size 15 x 15. This means that you place the counters on the vertices rather than within the squares on the board.
In the game, players will take turns placing counters until a player has managed to connect 5 or more counters in a row.
The player that goes rst will be AI player who has the black counters. According to the Renju rules it must play their rst move in the center.
To make the rules fair AI player is not allowed to make an overline i.e. win by creating more than 5 in a row. The AI player is also not allowed combinations of moves such as a three-three or a four-four. Human player is not restricted in anyway.
Additional Renju rules restrictions such as Choice Rule and a like is not implemented.
