1. Lock the figure as soon as possible to avoid loopholes: Generally, fencing games start from the corner of the figure, and the outer corner of the figure expands and contracts step by step, so the enclosure will naturally end. If there are loopholes in the enclosure, it will be blocked early to prevent opponents from giving play to their advantages.

2. Flexibly change your thinking: you can take different defenses according to your opponent's different strategies, seize the opportunity that initiative is helpful to attack, protect your own loopholes and attack your opponent's loopholes, and also protect your body and mind at key points according to your opponent's strong defense and weak attack.

3. Take the initiative to attack: seize the critical moment, attack in time, occupy as many loopholes as possible, and form a group to control the overall situation.

4. Clever use of "cut" and "continuous" skills: when attacking, we can cut the opponent's son in two ways, so that the opponent can't launch an effective attack, and we can successfully encircle the land.

Rule evolution

Go rules are formed through historical development. The ancient Weiqi game is basically the same as the modern Weiqi game, and the rules for calculating the outcome in ancient times are the same as those in China now. All the items are empty, that is, the living items on the chessboard are empty points.

"Empty" is a broad concept here, which always refers to a closed area, not just a closed empty point. The essential difference between the ancient and modern rules of Go is that many children won the ancient Go. In the Tang and Song Dynasties, the method of calculating Tao (refer to the daily rules in "Forget Worry and Enjoy Happiness") needs to deduct the eye position and ignore the public spirit.
