yea im think that too 
If all 4 corner squares are black then there must be an odd number of squares on each side of the board.  I don't know how many squares are on a checker board.

if squares are alternately black and red which makes sense i guess then the relationship ix b = r + 1.

welshfella · Answer

or b - r = 1
