But in 1911 he scored a convincing win in Karlsbad, crushing Akiba Rubinstein and Carl Schlechter with the same line of the Ruy Lopez.

He even won as Black against Alekhine in this match at Berlin 1921: They played a seventh tiebreaker game to determine the match winner, a French Defense Alekhine won with the black pieces.

Teichmann's records against Emanuel Lasker and Capablanca were poor (+0−4=0 and +0−2=1); however, he scored wins against all the other leading players of his day, e.g. Carl Schlechter (+4−2=21), Frank Marshall (+7−7=17), Aron Nimzowitsch (+1−1=5), Siegbert Tarrasch (+5−7=2), Akiba Rubinstein (+5−6=11), Géza Maróczy (+1−2=12) and David Janowski (+4−5=4).

Today Richard Teichmann is most commonly attributed as the author of the quotation "Chess is 99% tactics," which does not appear in any of his publications.

It appears that it was said by him in a private conversation with the Swiss chess master Erwin Voellmy, who later published a series of books on tactics and wrote in one of the volumes: ‘...the great master and teacher Teichmann explained to me years ago in Zürich (although he slightly exaggerated): “To 99% chess consists of tactics”.’[5] This biographical article relating to a German chess figure is a stub.
