For the sake of beating a wise opponent — who is aware of the basic structures and knows what to block and gomku which moment — you need deeper-constructed structures. One of the two arguments must fail.

Go-moku and threat-space search. At the position below black has a VCF from the 14 th move although it seems white has won the game with his double threes stone I am author of Hewer gomoku program and Gomocup organizer and I can tell you that it takes you very long time to write good Gomoku AI.

There are other ways to win, too: Nowadays, most of the state-of-the-art gomoku algorithms are based on the alpha-beta pruning framework. Experienced players will recognize gomou futility of continuing the pattern and will play elsewhere. All the moves stratfgy white are forced.

This means that if white turns, he can avoid being defeated by blocking the four. For gomoku, winning strategy has been already found. But if we form “open four”, like this: In the end I attach my last and most useful piece of advice. After this ceremony the players keep on moving till someone gets five in a row. I created a gomoku player once and it was quite succesful using alpha-beta pruning and giving each position a score dependent on how many half-open and fully open 2s, 3s and 4s each player had.

These are among the first things a player learns after understanding the rules. You know the basic attacking structures and the theoretical part is clear. By now you must be aware of the minimal basics of the game.

To capture stones in a ladder, a player uses a constant series of capture threats—called atari—to force the opponent into a zigzag pattern as shown in the diagram to the right. It is noticeable that if black starts to attack directly he will be in trouble at the 13th move because white can block black’s attack with an open three. I’m actually writing strategyy a significant variant to Gomoku, basically xtrategy game does not end when one got five in a row. In general, stones on the third line offer stability and are good defensive moves, whereas stones on the fourth line influence more of the board and are good attacking moves.

The unbroken row of five stones can be collected in the gmooku and in the edge of the board as well. Wow thanks very much Tomas!

In the opening, players often play established sequences called joseki, which are locally balanced exchanges; however, the joseki chosen should also produce a satisfactory result on a global scale. Such a move is called a ladder breaker and may be a powerful strategic move.

Keeping opposing stones disconnected means that the opponent needs to defend more groups. You can simplify your job using Gomocup interface and write ‘only’ AI. Surely, if gomlku form “open three”, like this: You can add in a pre-computed early game and end-game to speed up those scenarios and then rely on a well-optimized tree-traversal heuristic for the mid game.
