Answers.Body: <p>I have looked at sources in Spanish (mainly Cuban) and most of them purport the same story (similar to that presented in the question) copied and pasted. However, a couple of sources present a somewhat different story.</p>
  <p>An <a href="http://www.tribuna.cu/deportes/2020-10-01/maria-teresa-mora-una-campeona-irrepetible" rel="nofollow noreferrer">article</a> in the journal <em>Tribuna de La Habana</em> says (my translation):</p>
  <blockquote>
  <p>With humility and pride she always kept in her memory the two victories and one draw she obtained against her virtuous teacher, José Raúl Capablanca. They say that, when asked about it, with shiny eyes she accepted to acknowledge those meritorious results, although she then explained to the inquirers that they had been possible during simultaneous games.</p>
  </blockquote>
  <p>Another <a href="http://www.lajiribilla.co.cu/2003/n088_01/088_07.html" rel="nofollow noreferrer">article</a>, in the cultural magazine <em>La Jiribilla</em>, mentions the story of the comment &quot;Such a pity, I won!&quot; But according to it, this didn't occur after wining Capablanca, but during a team tournament in 1960. I translated the relevant part of the article. The story was told by GM Silvino García:</p>
  <blockquote>
  <p>&quot;I remember the First National Championship between State Organisms —Silvino said,— a team tournament that was played in 1960, when I was making my first steps.</p>
  <p>&quot;María Teresa defended the first board of the Ministry of Education, where she worked, and had in front of her one of the strongest chess players in the country at the moment.</p>
  <p>&quot;She played a brilliant game, till she obtained the victory.</p>
  <p>&quot;Her opponent blushed, a bit because of tension, a bit for having lost against a woman. In accordance to the tradition, he congratulated her and then María Teresa, with that simplicity of hers, said to him in a low voice: Oh, such a pity, how I won you!&quot;</p>
  </blockquote>
  <p><strong>EDIT</strong></p>
  <p><a href="http://www.ajedrezpinal.com/la-discipula-que-derroto-a-capablanca/" rel="nofollow noreferrer">One of the games</a> was won by María Teresa during an exhibition given by Capablanca against 28 players at the Institute of secondary Education of La Habana on May 3rd 1941.</p>

  I have looked at sources in Spanish (mainly Cuban) and most of them purport the same story (similar to that presented in the question) copied and pasted. However, a couple of sources present a somewhat different story.
  An article in the journal Tribuna de La Habana says (my translation):
  
  With humility and pride she always kept in her memory the two victories and one draw she obtained against her virtuous teacher, José Raúl Capablanca. They say that, when asked about it, with shiny eyes she accepted to acknowledge those meritorious results, although she then explained to the inquirers that they had been possible during simultaneous games.
  
  Another article, in the cultural magazine La Jiribilla, mentions the story of the comment "Such a pity, I won!" But according to it, this didn't occur after wining Capablanca, but during a team tournament in 1960. I translated the relevant part of the article. The story was told by GM Silvino García:
  
  "I remember the First National Championship between State Organisms —Silvino said,— a team tournament that was played in 1960, when I was making my first steps.
  "María Teresa defended the first board of the Ministry of Education, where she worked, and had in front of her one of the strongest chess players in the country at the moment.
  "She played a brilliant game, till she obtained the victory.
  "Her opponent blushed, a bit because of tension, a bit for having lost against a woman. In accordance to the tradition, he congratulated her and then María Teresa, with that simplicity of hers, said to him in a low voice: Oh, such a pity, how I won you!"
