Baduk Board Game

http://pastebin.com/cPgmvZsZ

Here are the 5 classes in my game of Baduk, Weiqi, Go, or whatever you want to call it.

I would like some help, preferably soon (I'm on a tight schedule), if you're willing to give it to a novice programmer.

Most importantly, I cannot figure out why when I surround a stone or group of stones, I do not capture them. It must be an error somewhere in the three capture functions, but they appear fine to me.

After that, I'm looking for help in my coding style. Any suggestions or tips you can provide would be appreciated.

Thank you in advance.

I'll actually do that right now. Maybe you'll see this post. You won't need to know Java because the problem is with the logic in the check capture functions.
