Judge Hans Gruber (Best Problems 105/2023, p.572-576): "This is a miracle! Although the author showed in a number of publications around the year 2000, that hundreds of threefold chameleon echoes exist in problems without twinning, which seriously limits the innovation value of such problems, I consider this problem – with only two echoes – as outstanding. The quality of the moves and the reasons why their order is unique, is fascinating. Why should manoeuvres by the black king and the white queen (!) be unique on an open board, without constraining fairy conditions, and with the need to reach in two solutions two opposing edges of the board? The provision of appropriate hurdles for the grasshoppers is the key feature. The ingenious find is that the move Db1 (played at different moves) constrains the black king to the a-file in the first solution while it offers him the whole board for a virtuoso slalom run in the second solution. A sensational problem in terms of agility, and I do not care that the computer helped to find it. Still, the composer had to discover this gem in an almost infinitely large data base."
