Chess Problem 1992c6a401


Problem Observer, 1992


(b) wBb6<–>bPc5
GRASSHOPPERs d8, e7; d5

a) 1.Gg5 Gb4 2.cxb4 Gh4#
b) 1.Gb7 Ga5 2.bxa5 Ga7#

In each solution a black G goes to a square on which it is used as a hurdle by White’s mating move. One white G sacrifices itself for self-block while the other one mates. WinChloe opines that this problem illustrates the Zilahi theme, and I suppose it does, though I knew nothing of such a theme in 1992.
