Chess Problem 1977e4c401

BDS

British Chess Magazine, 1977

#2
U-Chess 

1.R-Q2  (2.BxP)

1...P-R4 2.RxP
1...P-N5 2.PxP
1...P-B6 2.NxP
1...P-B4 2.R-Q4

All the defences are pawn-moves to make the threat ambiguous. In the first three they make a previously ambiguous move unambiguous. 1...P-B4 adds a second fatal guard to d4.

The first chess problem I ever composed.
