Renju (Japanese: 連珠) is a professional variant of gomoku. It was named renju by Japanese journalist Ruikou Kuroiwa (黒岩涙香) on December 6, 1899 in a Japanese newspaper Yorozu chouhou (萬朝報). The name "renju" comes from the Japanese language, and means "connected pearls" in Japanese. The game is played with black and white stones on a 15×15 gridded go board. The rule of renju weakens the advantages for the first player (Black) in gomoku by adding special restrictions for Black. (Wikipedia).
