W.E.Lester
Fairy Chess Review October 1940 (#4606) *
Mate in 2 with set play.

Solution: Set: 1...d5/Gd5 2.Nf4‡
Play: 1.Ga8 d5/Gd5 2.G×g8/Ga6‡

Comment: Mutate. A sort of Grimshaw; but each piece is not merely interfered with by the other but totally immobilised so that WG can use it as a hurdle to give check.

* The position was corrected in the December issue, all pieces except Ra7, Ga5 being moved one file right to avoid a dual.
