The idea of placing all 3 Super Knights on the board goes back to The Sultan's Game, an 11x11 variant invented by L. Tressan in 1840. EDIT: and goes back centuries before that, as Jeremy commented yesterday. After posting my Unicorn (Great) Chess variants, I somehow managed to forget all about the pieces in the original Great Chess!
