Loyd,S London Era, 1861 1.b4! Rc5+ 2.bxc5 a2 3.c6 Bc7 4.cxb7 Bxg3 5.bxa8Q# 1-0

The theme of starting a pawn on its initial square and make it give mate in it's fifth (promotion) move came to be know as the "Excelsior" theme, after youth in the famous Longfellow poem. It had been tried before, but Loyd's problem remains to this day the most surprising and perfect rendering.
