My thanks for your very detailed answer. Your selection and the suggestions of others would seem to be very full and open over a large area of consideration. Like one other gentleman who mentioned it, I do like chess, but I am not very good at it, simply because it is difficult to think twelve moves ahead, particularly when your opponent is doing the same thing!
Checkers is really much more fun!! 
Thank you again for your response.
Respectfully;
Marcus Audens
