The Problemist, 1992 (amended)


Mate in 2
Checkless Chess

A two-mover featuring the fairy form Checkless Chess, whose sole difference from orthodox chess is that a check is only legal if it gives mate.

My apologies to solvers. The diagram posted yesterday has no solution. I took the problem from a database and assumed it had been tested. I have added a white rook at h6, which makes the problem sound and preserves the clever idea, though I am not sure the composer would approve of the drastic means.
