Abandoning a child can be used to give up an unfavorable situation, contain an opponent's attack, divert attention or create an advantage in Go. The use of abandoned children needs to consider many factors such as the number of chess pieces, current position and target, and needs careful thinking and continuous optimization.
Abandoning children is not only a choice in competition, but a certain strategy should be made from the beginning. Because at the beginning of Go, the layout of each player can have a vital impact on the attack and layout behind it. Therefore, it is necessary to accurately judge the current situation at the beginning, determine which pieces are unimportant or can't be taken into account, and then formulate further strategies after giving up, so as to better develop the next attack.
