“…The diagram was O.K. but the Forsyth verification incorrectly showed white P at g6.”
The opposite was true. The diagram had a black p, and the Forsyth lists row three: "3NR1P1". Analyses (with his provided keys in the following week paper) come up as mate in 4, but it is possible to extract mate in two; i.e., 1. Kb4 Bxd6+ 2. Rxd6#
