[DhtmlXQ_comment0]目的要求：在上一局的基础上，学员应进一步搞清并能够熟练的掌握本布局的各类变化，有一定分析局面的能力。||重 点：开局中的出子和占位关系；有效步数问题。||难 点：开中局过渡时的形势判断和攻击点的选择，各变化的优劣情况。在对局中正确的选择对自己有利的变化。[/DhtmlXQ_comment0]
[DhtmlXQ_comment18] 上节课我们介绍的是象３进５变化，本节课我们来看黑方此时走象７进５的变化情况。其他变化我们下几次课再加以介绍。[/DhtmlXQ_comment18]
[DhtmlXQ_comment19] 如果红方此时走炮五平七，则炮2进4（车８进５，炮八进二车８进３， 士六进五马７进８，车四平三炮２退１，相七进五红方较优），相三进五炮２平７， 兵七进一象５进３，马六进八马３退４，车九进一卒７进１，车九平六车１进１， 炮七进四象３退５，炮八平七车８进４，马八进六车８平３，马六退七车３平２，前炮平六红方先手。[/DhtmlXQ_comment19]
[DhtmlXQ_comment21] 另有一变化，即炮五平六以下卒３进１，兵七进一车８进５，兵三进一车８平７，马三进四象５进３，相三进五车７平８，炮八进二卒７进１，马四退三车８退１，炮八平三炮７进４，车九平八马３进４，车四平三炮２平４，车三退二象３退５，士六进五车１平３，车八进四双方平稳，红略好。[/DhtmlXQ_comment21]
[DhtmlXQ_comment22] 若此时黑方改走炮２进１，则车四进二炮２退２，车四退五车８进８，炮八退一车８退２，炮八进三卒１进１，马五进七车１进２，车九平四卒３进１，兵七进一象５进３，大致相当。[/DhtmlXQ_comment22]
[DhtmlXQ_comment40] 如果黑方此时走车8平5，则红方车四退六！（如车四退五则黑方有车5进2之着红方不好）伏马六进四，红方优势。[/DhtmlXQ_comment40]
[DhtmlXQ_comment45] 红优。[/DhtmlXQ_comment45]
