The Black Death Swindles for a Mating Combination

Joseph Henry Blackburne was known as the 'Black Death.'  For over 20 years he was one of the top 10 players in the world.  Here is a game in which he swindled the great Adolf Anderssen.  Blackburne was losing playing the White side of a King's Gambit Accepted when Anderssen allowed him to create a mating combination.  See if you can find the refutation.
