[DhtmlXQ_comment0]一盘棋的战斗过程,通常划分为开局、中局、残局三个阶段.对局开始的阶段,称为开局.此时主力棋子都位于自己阵地的后方,需要开动出来,调到重要的位置上去,并互相配合,构成一个战斗阵形,利于发起攻击或实施防御.因此,开局的任务是调动子力布署阵形.在这过程中,双方子力初步接触,展开前哨战,先走的红方取攻势,后走的黑方取守势或对攻.现举五七炮对屏风马进3卒局例.说明如下:[/DhtmlXQ_comment0]
[DhtmlXQ_comment20]至此形成图局面,可以看出:1.双方车马炮强子已大体上出动;2.双方阵形结构已基本定型;3.双方攻守意图已初步显露.因此,开局任务完成,将向中局阶段过渡.||从理论上讲,单方六个强子开动起来,约走六步棋,主力兵种还要多走一两步,加上挺兵补士相等,总共10至12回合左右,具体到各种开局阵形亦不相同,有的短些,有的长些.||对于初级棋手来说,掌握开局12回合的定式着法,已达到要求.对于中、高级棋手,则需往前推演各种开局变例,通常分析到15至18回合,进入中局的初阶段.[/DhtmlXQ_comment20]
