|White to play and mate in three.
}}
To the right is another relatively simple example, but this time it is two rooks, rather than bishop and queen, involved in the interferences. The problem, by D. J. Densmore, published in the ''Gazette-Times'', 1916, is another mate in three. The key is 1.Nb7!, which interferes with both rooks and so threatens both 2.Rh7# and 2.Rb1#. Black can defend with Raxb7, but this overloads the capturing rook, so white can play 2.Rb1+ Rxb1 3.Rh7#. The other capture is similar: 1...Rbxb7 2.Rh7+ Rxh7 3.Rb1#. Whichever rook captures, it interferes with the other and becomes overloaded, having to defend against two threats on its own.
