Who will analyze gobang gossip?

Gobang Bagua Array is a powerful measure to prevent Gobang from getting separated. The so-called gossip, in fact, is just a horse stance just to catch each other's gossip points.

Gobang Bagua array moves like a horse in chess.

As the picture shows, white chess is in the gossip of black chess.

In this way, white chess can only add four sons and one line at most.

Black can control the situation of white with less power.

All the black players are connected in the shape of a sun, which looks like a horse stance just look in chess. In the Eight Diagrams, every line is defended by sunspots, and white chess can't attack it. In the process of attack and defense conversion, the black side is easy to get rid of the hands of three roads and two roads. At that time, the white side will have no way to attack and defend, and there will be nothing but defeat. This array is the representative work of the tactics of "defending for attacking" in China folk traditional array.

According to the mathematical principle, it is concluded that when a chessboard of any specification (that is, X*Y, (X & gt=5, Y & gt=5 and x, Y∈Z*) is filled with all the positions that can be touched by this method, there are no consecutive vacancies greater than or equal to five on the straight line and diagonal of the chessboard. So when one side fills the board in this way, the other side can't win.
