\section{逢方必觑}
\setcounter{tuxxx}{3}%图编号从4开始
{\heiti 题解}：``方''是下棋时经常出现的棋形，如图一所示。图中白1叫``觑''，又称``点方''。为什么要叫它觑呢？就是斜睨着A位的断。它是``刺''的一种，但又不同于刺。图二中黑1叫刺，是比较激烈地要断，而觑则比较缓和些，目的是破坏棋形。\par

这样也是白方比不点方被黑先在方处补一手稍好。因为点方后多了利用，如白有1至7的做劫，白如胜劫，黑边及角均要受到侵削。由本图可知，点方不光是猛攻时用，有时只是为了使对方棋形稍不完整。\par

\tx （凑着）：白1逢方必觑攻击黑一块，但却是凑着。黑2补后再4跳，反而加快了逃走的步伐，所以白1应直接3位压，黑便不能跳。\par
为什么出现这一例外呢？原来本图的主要矛盾不是白破眼而是黑向前逃，点方只能起到破坏棋形的作用。故点方适得其反。\par
{\heiti 小结}：``逢方必觑''在布局、中盘和官子阶段均适用，和``二子头必扳''一样，是培养局部感觉的。\par
