Need help with a game algorithm (Go/Wei-Chi)

[CaptainJack]

I've decided to write a "Go" aka "Wei Chi" game in C++ because I'm masochistic I like a challenge and needed an excuse to brush up on my C++ skills.

I'm having difficult figuring out an atari finding algorithm though and was wondering if a human calculator someone smarter than me could figure it out for me help me.

The game interface is ASCII and I've chosen the space options to be..

Empty: .
Black: B
White: W
Atari: *
