[plt-scheme] A question about an implementation

Hello, I program the play of Othello, and I would have a question in
connection with the structure of implementation. I thought of creating 8
lists, 1 lists by line in made, containing each one 8 elements and of making
a accessor of the cxxxxr type i.e. avoided a too great complexity.
I would like to know if there would be a structure more adapted @ kind of
situation. My goal of being modelled the boxes of the plate of play in order
to preserve the blows played and to analyze has each blow kel not must be
eaten.
Thank you by advance for your answers
