In 1866, Anderssen lost a close match with 30-year-old [[Wilhelm Steinitz]] (six wins, eight losses, and no draws; Steinitz won the last two games).<ref name="Matches1865To1879" /> Although Steinitz is now known for inventing the {{chessgloss|positional play|positional}} approach to chess and demonstrating its superiority, the 1866 match was played in the attack-at-all-costs style of the 1850s and 1860s.<ref name="SilmanSteinitz">{{cite web

}} Has several examples of Steinitz testing his theories in top-class play.</ref> This is generally seen as the point at which Steinitz succeeded Anderssen as the world's leading active player. Although ideas of a contest for the world championship had been floating around since the 1840s,<ref name="Spinrad2006EarlyWorldRankings" /> the 1866 Anderssen–Steinitz match was not defined as being for the world championship, and many were opposed to the claim of such a title while Morphy was retired from chess and still alive.  Furthermore, Anderssen remained dominant both in top tournaments and in personal matches against Zukertort until 1871.<ref>{{cite book | title=The Centenary Match, Kasparov–Karpov III | author=[[Raymond Keene]] and David Goodman | year=1986| pages=1–2 }}</ref>
