Same fairy pieces starting in helpmate 2
This is the 2nd special example file for 19th TT CCM.
We have already seen various motivations in both economic and crowded positions. But a lot of pieces on
the board needn't necessarily mean that the problem is badly constructed. It might mean that the idea itself
requires a lot of wood or that despite simple basic scheme the soundness cannot be achieved without
hard fight against cooks. So below I have selected 5 problems with at least 16 pieces on the board, but where
most of moves, if not all, are played by the same type of fairy piece.
1st Prize Springaren Christmas Tourney 1994-1995
1.Ge6+ Ghb4 2.Gdb3+ Ge7#
1.Gf6+ Gbb4 2.Ghb3+ Ge7#
1.Gd7+ Geb4 2.Gb3+ Ge7#
One of the problems that absolutely stunned me when I saw them for the first time and that I remembered forever from
that moment. To my surprise I have not it on CCM yet, so its time has come.
On h-file, first row and NW-SE diagonal
we have familiar chinese (or lion, if you want) pin-battery configurations. To mate, it is necessary to put wG on b4
(guarding b6 and d4), something to b3 (as a hurdle for Ga2 guarding c4) and give check, e.g. with wG from e7.
So black grasshoppers jumps cyclically to b6, prepare hurdle for wG jump to e7 or stay on line, while white grasshoppers
cyclically guard b4 passively, jump to b4 and mate from e7. Everything works perfectly here, strategy, geometry and
formalism. (The only small defect is that 1.Gf6 opens line of Gh3 to b3 - not repeated in any other phase.)
4+3 grasshopper, 0+3 lion
