Why can't gobang double three?
The reason why Gobang can't double three is because the hand is forbidden. If there is no hand ban rule, you can double three.
Generally, the gobang played by the people is not very formal, and there is usually no prohibition. Basically, the forbidden hand is only used in regular competitions.
Gobang is forbidden because the advantage of the first hand (black side) is too great, and the forbidden hand is born to weaken the advantage of the first hand (black side) and balance the gap between the first hand and the second hand.
The so-called double three, the technical term is "three three", also known as three three forbidden hands, which means that a piece of black falls and can form two live three at the same time.
One thing to pay special attention to here is; The pieces left by the black side must be a combination of two pieces. No, it's just part of living three.
Living three refers to the basic form that the next piece can form living four. For example, jump live three, even live three belong to live three.
There are double three forbidden hands, double four forbidden hands and long companion forbidden hands.
Gobang has different names in different countries. For example, the Japanese call it "middle-aged and elderly chess", which means that this kind of chess is suitable for the physiological characteristics and thinking mode of middle-aged and elderly people.
