[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:
