This is the hippety hop piece. After 15 years of exploration this is probably as far as we have got in acceptance fully of alternate pieces. (No one takes seriously centuries-old Ferz and Dabbaba, but everyone admires Nightrider.) Dawson invented NN 100 years ago soon, and Nightrider is it for the bench or the pedestal. 'NN' is not so much Betzaesque but problemists' usage for decades. Sissa goes to Nightrider squares differently. Does the solution here 'e5-d7' work if NN is Sissa instead?
