Die Hinterstellungskombination, erstmals von Laws dargestellt, wurde von Loyd unter dem Namen "American Indian" populär gemacht. Die vielen überflüssigen Steine hat Loyd aufgestellt, um die Stellung als Partiestellung erscheinen zu lassen und das Lösen zu erschweren.

The problem won '2nd prize for 2#', but in difference to the 1st prize for #2 it was not awarded by the judges, who did have the authority to do so. Instead they gave the problem a honorary mention, and the tourney management awarded it the '2nd Pr. for #2'. (2022-12-15)
