Mate in two(628)

White in two   by L.I. Loshinsky    1960

That's a really difficult one by one of the famous names. Look at it later.

Got it! Not as difficult as I feared after all. Lots of stuff going on with the h1-a8 diagonal. Wonder if some formal theme is shown in this twomover. I'm not so good in identifying named themes in problems.

This puzzle was in the chapter called"Patterns",  Across more than one phase, cyclic refutations,cyclic change.

Yep! Doesn't have a name, but is more of a modern schematic problem. The set play, the variations and tries are designated by the letters A, B, C etc. and you see these (re)appear on differents points of the 3 phases. I haven't identified the precise cyclic shifts yet. Guess I should be doing some more work on this problem.

You would probably love the book these puzzles come from.

At this point in my life I am actually very happy when nice people like you post the problems they appreciate and their thoughts about them! When I have the book on the shelf, I am not likely to pick it up and do it A -Z.

Thanks a lot for the great specimen in your posts!
