Solutions for Motley Helpmates{A} {B} {C} In these three, every move is a non-capturing check. {B} came first. It is cluttered, but it did win me a bottle of wine for my father. Then came {A}, and then Michel Caillaud found {C}, where no pawn checks are needed. Michel believes a 3.5 would be very difficult without a pawn check, and absolutely necessary for a 4.0. I am not sure that either of these would exist, with or without a pawn check, but if anyone could find one, it would be him. A related composition is: H.-P. Reich & A. Schöneberg Probleemblad 1992 where all moves are checks, but the last is also a capture. Another interesting one by Bachmann, Schöneberg & Reich, is an all-check h#8 with many captures, from an initial checking position. {D} Note that Kd6 occurs in 2 lines. This overlap is perhaps best avoided in a version with Nicolas Gonnin (3n4/6P1/2p5/3k4/BK6/8/8/8), but that one has other costs, and I prefer the current version. {E} Although there are dozens of published compositions with this material, research in PDB turned up only one possible anticipation of the mating matrix, in a cooked h#2 by Lajos Riczu. The second mate noted in PDB can also begin 1. Kb3 and is evidently a bug. This composition was unplaced in the Gábor Cseh Memorial Tourney where the idea was for an h#2* to show an identical chess-problem motif in each line of play. The problem is probably too simple - the most interesting feature is an invisible one - the pieces can't be shifted wholesale in any direction without allowing a cook (unless they are rammed right against the edge of the board). So the little composition is unique. {F} 1. Rg7 Be8 2. Bg6 Sg4#. {G} My thanks to Nicolas Dupont, Michel Caillaud, Dan Meinking, Rolf Wiehagen and Nicolas Gonnin for help at various points in the production of this page. |
