A traditional weiqi set, with floor board , bowls and stones.
Nowadays players use stones with high brightness contrast, i.e. black and white.
The general strategy of Go is to expand one’s territory where possible, attack the opponent’s weak groups (groups that can possibly be killed), and always stay mindful of the “life status” of one’s own groups.
The ko rule bases on this rule: Players are not allowed to make a move that returns the game to the previous position.
NOTICE: Placing stones in turn is nothing but right for both players. Instead of placing a stone, a player may pass. This usually occurs when they believe no useful moves remain. When both players pass consecutively, the game ends and is then scored.
Different rules deal differently with forbidden moves. Players must remove the stone and pass the very turn by Modern Chinese Weiqi Rules. On contrary, Ying’s Weiqi Rules allow players to “commit suicide”
Because Black has a first move advantage, the idea of awarding White some compensation came into being during the 20th century. This predetermined compensation, called “komidashi,” (“komi”) means that for even games white may receive somewhere on average of 6.5 points compensation for Black’s first move advantage. If there is one stone difference in strength between players, the stronger player takes White, and White may receive only .5 points komi, just to break a possible tie. In handicap games with 2 or more handicap stones, White may also take .5 points komi to break a tie.
When both players pass consecutively, the game ends and is then scored. Judge compares black’s points with white’s.
As for seki (mutual life) situations, both player receive 0.5 points from each ‘public intersection’.
As we do not have all day, I have to stop introducing rules to you. If you are interested, just search and test after class. Or you may well ask me!
China Weiqi Association had carried out some rules in weiqi ranking in 1992, but rank setting still differs from city to city.
For example, the system in 1992 set 25 kyus, while Beijing and Shanghai make 11. Amateurs show their strengths better in Hangzhou’s rating matches.
Whatever differences there are, 9-dan systems are adopted by amateur and professional matches all over China.
Weiqi in modern times
Right after the opening-up, the architecture with three pillars of China, Japan and South Korea gradually formed up. In the late 20th Century, Japan didn’t catch up with the its opponents for stubbornness, since when China and South Korea have form a fierce one-on-one competitive situation in weiqi circle.
Philosophy sense of Weiqi
Corresponding to the nature of universe.
1. Master Wu Qingyuan drew the conclusion that weiqi was rather an astronomical tool than battlefield model. The board stands for the sky, and stones for stars.
2. Equal distribution is the most important property of the board. No pre-settled region. Modern cosmology(宇宙学) proves that matter and energy distribute equally in Large space.
Yin and yang elements.
Ancient Chinese philosophers believe that the world was formed and motivated by yin and yang elements. The color of weiqi stones, black and white, indicates the confrontational movement of yin and yang.
3. Equality values. Weiqi stones only differs in position.
4. System thinking. Etc……………………………..
