就是给1000分，估计也没有人为这个给你写代码。因为来这里的高手才不稀罕分数，而低手又写不出来。

不过，我可以给你提供一个思路。

这个，可以用深度优先搜索算法。

提供一个伪代码给你：

//写一个估值函数
int 获得价值（ int nPlayer， int x, int y )
{
// 函数说明：
// 假设把棋子落到x,y处，所能获得的价值。
// nPlyaer == 1表示黑方，nPlyaer==2表示白方

1、判断如果是赢（横向、纵向、斜向五个连起来）就返回无穷大（一个远远大于最高价值的值，例如1000）
2、判断如果是双冲4，返回 200
3、判断如果是冲四活三，返回150
4、判断如果是双活三，返回100
5、如果挨着自己的棋子，两头又有空隙，返回50
6、其他的有利的判断。。。。
7、返回以上判断的价值
}

//写一个获得最佳位置的函数
//int 获得最哗培佳位置( int 黑方或白方, int 层数, POINT& 返回位置 )
int GetBestPosition( int nP, int n, POINT& ptBest )
{
1、枚举所有可以落子的位置。
2、假设将棋子落到该处。
3、获得该处的价值（ 保存在 int nJiazhi ）;

4、如果层数＝＝1，转到第7步:;
5、否则：
6、//递归的调用GetBastPosition( 对方, 层数减一 );
nJiazhi －＝ GetBastPositon( nP == 1 ? 2 : 1, -- n );
7、找出所枚举的所有的落子点中价值最高的那个位置。
8、将7中找到的位置存入ptBest，返回nJiazhi.
}

说明一下：
层数，就是想让程序袭明能够考虑几步。

总体的思路就是，搜索所有可以落子的地点（当然可以优化，比如远离交战焦点的地方可以忽略），假设将棋子落到该处，然后评估这个位置的价值，再减去敌人能获得的最高价值，就等于这个拍芦告位置的实际价值，找出实际价值最高的点，就是最好的落子点了。

最难的就是写估值函数。一个良好的估值函数，加上搜索的一些优化，就是一个很好的博弈算法。

以卖羡前我也有想过电脑下五子棋的思路。
和楼主的想法是完全一致的，难点也是在如何智能下棋的算法，
我觉得这个需要把所有可下的位置进行比较，选择一个最优的。至于具体算法本人也没想出什么结果。

不过我觉得这是人工智能的知识领域，计算机专业研究生都开着门课程。
正是包含这样的问题的解决方法，楼主有空可以学习下。

我觉得即便是从网上或者从别人那里得到一个答案中御拍而且理解思路，由于拆姿没有系统的学习过这方面的知识，也不太利于融会百通。不如系统的学习一下，使自己提高一个层次，再遇到其他属于人工智能问题就可以迎刃而解，

我曾经写过五子棋，现在已经忘了具体的部分。
不过我可以把我的写“电脑”下棋的部分的思路晌哪给你说哈。我是使用“二叉搜索亮正树”来解决对电脑应该怎么下棋，遍历所有能下子的路径，找寻最优化的路径。

这个还扯不到人工智能哈。。只能算是粘了点敬谨悔边边。如果真的是想要达到人与人下棋的那种成度，你可以用CList建一个危险点的列表集,对电脑下子前，用搜索树优先遍历这些点。[个人意见，哈哈]

两个办法：1.找你所在地区的大学相关专业的高年级学生联系下拿竖，请他们利用手头资源帮你找个类似的程序按你的要盯基求改好，因为现在基本所有大学都有相关的社团或兴趣小组玩这个，五子棋更是很基础的...（找到人后估计再半个小时就好了）
2.留个邮箱，人家以前如果做过这个的可以直接发给你（估计人家看到你邮箱再5分钟发信过去就好了）
另：刚才我看了下，我手头能进的3个大学的论坛都有现成的，估计其他大消则大学也很好下，但不是我做的也不好把人家的成果拿来炫，你就找做过这个的人吧
