Re: Retrograde problems

I like these kind of puzzles, but I doubt many people here would be interested, since you can't complain about the draw margin in these puzzles.

Re: Retrograde problems

The rules don't specify it but I assume that white has the move in all these diagrams?

The examples:
Spoiler:
1: 1. 44-39 33x44
2: Either 34-29 23x34 or 34-30 45x34
And the diagrams:
Spoiler:
1: 1. 21-16 25x21
2: 1. 20-15 16x20
3: 1. 34-29 15x23
4: 1. 33-28 25x23
5. 1. 28-23 26x28
