Editing Adolf Anderssen (section)

===1866–1879===
By this time tournaments were becoming more frequent, and the round-robin format was adopted.  At the same time, Anderssen, after losing the match to Morphy in 1858 and to Steinitz in 1866, rededicated himself to chess, particularly studying both [[Chess endgame|endgames]] and positional play.  The result was that Anderssen, in his early fifties, was playing the finest chess of his career.  As a result, Anderssen compiled a very successful tournament record in the late stages of his career: five first places, two second places, two third places; and a sixth place in the final year of his life, when his health was failing.<ref name="storiascacchiTorneiAl1879" /><ref name="endgameNLWorldExhibitions" /> One of his first places was ahead of Steinitz, [[Gustav Neumann]], [[Joseph Henry Blackburne]], [[Louis Paulsen]] and several other very strong players at the [[Baden-Baden 1870 chess tournament]]. In terms of the number of leading players present, this could be regarded as one of the top 20 tournaments ever.<ref name="sympaticoStrongest Tournaments">{{cite web|url=http://www3.sympatico.ca/g.giffen/tournaments.htm |title=The Strongest Tournaments in Chess History |access-date=17 June 2008 |url-status=dead |archive-url=https://web.archive.org/web/20070502142528/http://www3.sympatico.ca/g.giffen/tournaments.htm |archive-date=2 May 2007 }}</ref><ref name="chessmetricsFormulas">{{cite web | url=http://chessmetrics.com/cm/CM2/Formulas.asp?Params=199510SS0SS3S000000000000111000000000000010100#ClassExplanation | title=Formulas | access-date=17 June 2008 }}</ref> One of Anderssen's third places was at the strong [[Vienna 1873 chess tournament|Vienna 1873 tournament]], when he was 55. About half of Anderssen's tournament successes came at championships of the different regional German Chess Federations; but these were open to all nationalities, and most of them had a few top&nbsp;ten or even top&nbsp;five competitors.<ref name="storiascacchiTorneiAl1879" /> Anderssen usually beat Zukertort in matches, but his dominance came to an end in 1871.

The Leipzig 1877 tournament was organised in his honour and named the "Anderssen-Feier" (Anderssen Celebration);<ref>[https://books.google.com/books?id=OZjIENcRpNUC&q=Anderssen-Feier&pg=PR5 "Anderssen-Feier", Deutsche Schachzeitung, 1877]</ref> Anderssen finished second in the tournament behind Louis Paulsen.

Still at Leipzig, Anderssen lost a match against tournament winner Louis Paulsen (three wins, one draw, and five losses). Matches were Anderssen's relative weakness; his only match win in this period was in 1868, against the 26-year-old [[Johann Zukertort]] (eight wins, one draw, and three losses).<ref name="Matches1865To1879" />
