(二)禁止着法和允许着法怎样划分? 《棋规》中规定,凡是单方面走出“长打”就属于“禁止着法”,必须变着,不变作负。而长拦、长跟、长兑、长献以及“一打一闲”等着法,均属于允许着法,双方不变作和。但是此处有一点值得引起注意,即所说的拦、跟、兑、献等,必须是双方处于对等地位或攻方无法变着,才能不变作和。否则,如有一方为“长打”时,则另当别论。现在列举两则形成鲜明对比 (B) prohibiting the law and allowing the law how to divide? “Chess” stipulates that those who unilaterally out of “long fight” belong to the “prohibition of the law” must be changed, unchanged. The long bar, long bargain, long bill, long offer, and “a dozen and a half” waiting for the law, all belong to allow the law, the two sides remain unchanged. However, it is worth noticing here that what is said to be such as barging, hecking, offering, etc. must be that the two sides are in equal position or the attacking side can not change in order to remain unchanged. Otherwise, if one party is “long fight”, then another matter. Now cite the two in stark contrast
