Enigmatic Variations 1490
BORICAHF by Piccadilly
The Playfair key phrase is KING CHARLES; when decoded, the unclued entries give COCKER, SPRINGER, BLENHEIM and the title likewise gives SPANIELS.
I found this puzzle in an old folder. Before submitting it, I had to change the Chambers date from 2013 to 2016, so the puzzle had been lying forgotten for at least eight years…so I can’t remember where the idea came from.
I enjoy Playfairs and I hope that solvers enjoyed solving this one.
