Persson-Horton, Sitges 2015 round seven. Position after 58. Rb7-b8.
During the tournament at Sitges I came across, can't remember why, some pages on Google Books from Klaus Trautmann's El Último Error, the Spanish translation of his book Der Lehtze Fehler, The Final Error, originally published in German in 2004. As far as I can see it's never been translated into English, which is probably a shame. Tim Krabbé mentions it here.
The subtitle of the book is 128 irrtümlich aufgegebene Schachpartien, which is more German than I can read unaided, but in Spanish is 128 Partidas Abandonadas Erróneamente, which I can render without difficulty as "128 games wrongly resigned", which makes it both a suitable introduction to this piece and ironic that I was carrying around the excerpt from Google Books during that particular tournament.
