Kibitz with Steinitz

Wilhelm Steinitz (1836-1900) was world champion from 1886 to 1894.  In 1862, he played in his first international tournament in London, which was the first British Chess Federation Congress.  Steinitz took 6th place.  The event was won by Adolf Anderssen.  Here is one of his games from that event where he played brilliantly.  He sacrificed a rook to expose the enemy king, then using his active pieces, found the mating line.  He missed a faster mate, but the results were the same.
