A.Buchanan: I prefer wS on e5 instead, which gives more freedom, including the surely tempting 1. Sf7? wSe3 is also interesting as in principle it might reach the mating square c3 in just 2 moves, but it has to cover a3 (2021-04-19)
A.Buchanan: Thanks Volker for locating a pre-existing version with Se3 at P1127276. (2021-04-20)
