Igor's Chess Doubles (ICD) #6 - A tale of a Broken Mill

I got a number of favorable response after posting my first set. Here is the next set. I will not post the answers or solution until after a week or so, to give readers a chance. You are welcome to send your solutions and explanations. Please don't use computer help. Use variations only as necessary. See my answers to ICD #1 as an example.

I hope you like these puzzles and my Chess Exam books.

Check these pairs of positions. For each pair

  1. Determine what is different between setups (A) and (B). White is always at the bottom (a1 = bottom left corner). 1 point for each pair.
  2. You always have BLACK pieces, no matter Who is to move determine if you (Black) would rather have position (A) or (B), or indifferent. Make sure you have a good reason! You get 2-10 points, depending on complexity. Adjust your score, if your reasoning wasn't 100%.

Maximum score for set #6 is 26. How will you do? Invite your friends to compete! Enjoy!
