Simplfy?

There is a simpler way to do this. To figure it out, try this exercise:

• Pick a starting row and column. Any row and column will do, but something near the middle is best.
  
• Figure out every ending row and column the bishop could move to from that start.
  
• For each ending row and column, subtract the ending row from the starting row and the ending column from the starting column.
  
• Look for a pattern in the two numbers you get by subtracting.
