The idea is similar to No 897 by myself and Thomas Maeder, but the setting is completely different – among other things, all thematic moves occur on a single line here. The fact that the non-thematic moves are located at different places in the two solutions here is not really a disadvantage, you can even say it makes for nice variety.

You shouldn’t regret anything and you shouldn’t add any “After…”!
Not remembering a problem by someone else (or by yourself) a few years later is not a shame, it happens to all of us now and then. And “After” should, I think, only be added if the idea and the matrix are very close to the earlier problem, and here at least the matrix is completely different. And your matrix has some advantages over ours, especially the fact that all the thematic action takes place on a single line in each solution.
(Being the judge, I don’t want to say more about the merots of this problem in relation to opurs right now, there will be more about that in the award in due course!)

Looking at both, I too agree with Widlert that the setting of both are different, though showing the same pattern of N-W-B. I think the pattern is a a theme to be explored in different settings.
