No.688 by Igor Kochulov – Non-standard mates after reciprocal creation of neutral batteries! (JV)

Definition:

Take & Make: Having captured, a unit must immediately, as part of its move, play a non-capturing move in imitation of the captured unit from the capture-square. If no such move is available, the capture is illegal. Promotion by capture occurs only when a pawn arrives on the promotion rank as the result of a take&make move. Checks are as in normal chess: after the notional capture of the checked K, the checking unit does not move away from the King’s square.

1. Geoff Foster says:

There are 4 neutral batteries (2 batteries with nQ that exist in the diagram, and 2 nR/nB batteries that are set up during the play). In each solution a check from a neutral piece is answered by a Take&Make double-check (setting up a neutral battery), which is answered by a Take&Make cross-check mate! The final move is made to d2, which is the nQ’s initial square. In each solution the nB captures the wRd4, and the nR captures the bBc4, with different “makes” each time. A very complex and enjoyable problem, although necessarily expensive in material.
