5.4 位置分值
给每个棋子一个固定的值，然后将所有还在棋盘上棋子的价值求和即得到。这种方法简单易实现，各种棋子的分值也基本体现了各种棋子的重要性。然而这种估值方法太过简单，一个棋子在棋局的真正价值，不仅与固定分值有关，还与所处位置，棋子间协作与牵制相关联。
同样是车，开局时车处在最边角的位置，只有一个走法。它此时既不能攻击对方，又不能对本方棋子形成更多的保护，使车的作用没有更大的发挥出来。开局时，一般要尽快将车出动到重要的线路上，让它发挥更大的价值。车的价值与它的位置密切相关。
卒是另一个重要的例子。在未过河前，卒只能向前走，基本没有攻击力，对将的保护也无力。过河后，可以横向移动，威胁更大，尤其当卒行进到对方九宫附件时，其价值大大增强。
定义一个三维数组来表示不同棋子在不同位置的分值，
static const unsigned char PositionValues[2][7][256]
第一维表示走方，0为红方，1为黑方，第二维表示棋子种类，0到6分别表示将、士、象、马、车、炮、卒，第三维表示位置。为了能快速求得每种棋子对应的下标值，特别增加一个辅助数组。
const char PieceNumToType[48] = {
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 6, 6, 6,
0, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 6, 6, 6
};
位置分值数组如下。
static const unsigned char PositionValues[2][7][256] =

代码技巧
要计算红方车在位置p的值，直接读取数组PositionValue[0][ PieceNumToType[23]][p]就得到了（假设此车编码为23）。
位置分值根据棋手多年的经验而得，有些难以量化，只能是尽量模拟。作者在此只是根据自己的经验做了一个初略的估值，读者可以根据自己的棋力来赋值。
