[C++] Chess game Terminal

Hi,
I'm trying to make a little chess game,
in C++, is in terminal because still I don't know a good GUI package for C++ sorry I'm n00b...

btw I got to print out the board:
like this:
[code]
-|--a-|--b-|--c-|--d-|--e-|--f-|--g-|--h-|
8|-bR-|+bk+|-bB-|+bQ+|-bK-|+bB+|-bk-|+bR+|
7|+bP+|-bP-|+bP+|-bP-|+bP+|-bP-|+bP+|-bP-|
6|----|+--+|----|+--+|----|+--+|----|+--+|
5|+--+|----|+--+|----|+--+|----|+--+|----|
4|----|+--+|----|+--+|----|+--+|----|+--+|
3|+--+|----|+--+|----|+--+|----|+--+|----|
2|-wP-|+wP+|-wP-|+wP+|-wP-|+wP+|-wP-|+wP+|
1|+wR+|-wk-|+wB+|-wQ-|+wK+|-wB-|+wk+|-wR-|
[\code]

and one can tell like in chess with the sentence "(e2:e4)" to move the piece from e2 to e4

but now what I need to make a AI?
I'll paste the code in pastebin so you can have a look:

I think it's easier to just write the chess program itself, the AI, and the GUI as three different things. After that, you can just link everything together using getters and setters.
