Gerd Wilts (2001-10-17): The retro play given in the solution serves only to justify that it may indeed be White's turn. The forward play indeed starts with 1. Bf7. The idea of TRD was to compose a problem which is legal but in which one of the knights must be a promoted pawn. TRD called this an "obtrusive Knight".

A.Buchanan: Garai, one of my favourites composers, has 1372 helpmates in PDB. (Only Jonsson & Feather have more.) Only 29 are not C+, of which 24 are marked cooked. Therefore the chances are high that the bug here is a typo too. (2015-11-07)
