本期开始,研究会将和棋友们一起探讨一下边的攻防。角部的攻防,己经有不少前辈做过专题撰述,大家常见的《围棋定式大全》、《定式大词典》等,都是这方面的佳作；而边的攻防,似乎少有专门的书籍。其实,边的变化同样多姿多彩,“边的定式”和“角的定式”均属棋家之必修功课。在正式进入本专题前,笔者想说明两点：第一,由于边的特殊性,其攻防都和周边的子力配置有关,所以笔者想结合一些常见布局一起探讨,这也是一种新的方式；第二,对笔者来说,这是次全新的尝试,由于实力、时间等方面的问题,难免出现遗漏以及错误(甚至是幼稚的、可笑的错误),也请棋友们予以谅解,并欢迎大家来信指正! Beginning of this issue, the study will be together with the chess players to explore the offensive and defensive side. At the corner of attack and defense, there have been many predecessors do thematic writing, we all common “Go set style”, “style dictionary” are all excellent works in this area; offensive and defensive side, it seems few special books . In fact, changes in the same side of the colorful, “side of the style” and “corner of the formula” are chess compulsory homework. Before I formally enter this topic, I would like to make two points: First, because of the particularity of the side, its offensive and defensive aspects are related to the configuration of the surrounding children. Therefore, I would like to discuss with some common layouts, which is also a new way ; Second, to the author, this is a completely new attempt, due to strength, time and other issues, it is inevitable that omissions and mistakes (even naive, ridiculous mistakes), but also for understanding and chess friends, and Welcome letter from me!
