Checkers Game

well i'm assuming you're using a two dimensional array on the board?

well just check to see if there is a piece diagonal to it, in the direction the piece is moving. if there is, check to see if the next diagonal is empty, if it is, you can move.

p - piece were checking
t - taken by opposite color
e - empty

|___|___|___|___|___|
| | t?| | t?| |

it's kind of hard to help you because you didn't explain how you were making it.
