I remember one particular problem I had been trying to compose for months. There came a night when I managed at last to express that particular theme. It was meant for the delectation of the expert solver. The unsophisticated might miss the point of the problem entirely, and discover its fairly simple, “thetic” solution without having passed through the pleasurable torments prepared for the sophisticated one. The latter would start by falling for an illusory pattern of play based on a fashionable avant-garde theme (exposing White’s King to checks), which the composed had taken the greatest pains to “plant” (with only one obscure little move by an inconspicuous pawn to upset it). Having passed through this “antithetic” inferno the by now ultra-sophisticated solver would reach the simple key move (bishop to c2) as somebody on a wild goose chase might go from Albany to New York by way of Vancouver, Eurasia and the Azores. The pleasant experience of the roundabout route (strange landscapes, gongs, tigers, exotic customs, the thrice-repeated circuit of a newly married couple around the sacred fire of an earthen brazier) would amply reward him for the misery of the deceit, and after that, his arrival at the simple key move would provide him with a synthesis of poignant artistic delight.
