Four-in-a-row for Lazarus

[Roland Chastain]

Hi Roland,

I downloaded this and had a couple of games, not bad

I like the interface, no clutter, simple and clean.

Hi! Thanks for trying my game.

I do have a question for you... why is the AI in another EXE? I'm not criticising, I'm just interested in the decisions/reasons behind it.

As I am interested in chess programming, I am curious to learn pipes and inter process communication.

Besides, it has some advantages : I can work on another engine, even write it in a different language, and try it at once from my GUI. I just have to edit the options.ini file.

The GUI runs the engine and sends as parameter the history of the current position, a string of characters from '1' to '7'. The engine computes his move, returns it (one character) and closes.
