I am amazed by the fact that Gomoku can be so hard to master with rules so simple you can explain to a five year old. And unlike Chess where there are a hundred year of theories to learn from before you can get going, Gomoku is still new. After a few weeks studying the standard surewin openings, you can expect to see things in a very different light and the game will get much more interesting.
Perhaps Gomoku is best known for programmers as a problem to solve. But it is nowhere near being solved. In fact, the best software are weaker than many top players.
I find Gomoku hits the sweet spot when it comes to my desire to play board games. It doesn't consume much of my time. I am always excited to find those long and obscure wins. I think the game needs more love from programmers like me.
