Dec-25-04  vonKrolock: From Sloan's article: <"Ruth Cardoso was for many years the strongest woman chess player in South America. She was eight times Brazilian Woman's Champion. She played four times in the Woman's Interzonal Championship. She played in many World Chess Olympiads, playing first board for the Brazilian team. Her trainer was Grandmaster Pal Benko.">

Feb-07-11  BLarsen1967: <vonKrolock> The game in the photo is this one (below) -- Cardoso's opponent Dora Rubio,she's the 'Grand Old Woman' of Braz. chess,winning 4 national titles,the last in 1962. After that Ruth Cardoso took over. A third strong player in that era was Taya Efremoff. - As for the legendary Dora C. Rubio,she has not one single game in this database.

Feb-07-11  vonKrolock: <BLarsen1967> Thanks for sharing this. A research on Rubio, Efremoff etc would surelly reveals more valuable material.
Feb-14-11  BLarsen1967: According to Wiki Ruth Cardoso did participate in the Malaga tourney 1971,thus her game here vs Bisguier is a genuine one. Also in Malaga she faced her own husband,Pal Benko,in round 8 (although it is unclear if they were legally married)

Ruth wasn't bad looking!

Feb-09-12  DoctorD: As you would expect from a student of Benko's, Cardoso tried her hand at endgame studies as well. Here is a game-like example.

Cardoso, Ruth
Sinfonie Scacchistiche, 1981
3rd Honorable Mention

The third through fifth moves, and the end of this composition are particularly delightful with the "backwards moves" by White, almost reminiscent of Reti - Black can queen also, but after White checks on g1, Black can either give up his queen and be mated in about 15 moves, or try to hold it with .. Kb2 and get mated even faster!

May-22-12  Yopo: Foi a primeira brasileira a conquistar o título de WMI em 1970. O lugar de nascimento pode ter sido Belmonte(BA).
Mar-16-24  vonKrolock: Article online in "Correio" (Bahia State) :

Relate, amongst other things, that she was daughter of a big farmer, important cocoa producer, and of a German housewife. That the family was in Germany when the war broke out in Setember 1939, and that:

quote <"The Volkl family, Ruth's maternal branch, was of Jewish origin. She was taken to the Nazi concentration camp, along with her mother. There, he would suffer from the barbarities of the Holocaust, carrying definitive consequences that would compromise one of his lungs. Because they had Brazilian citizenship, the German said, she and her mother would have managed, with extreme effort and the use of political relationships, to negotiate their liberation and immediate return to the tropics."> end quote

Mar-16-24  Granny O Doul: I'm pretty sure Benko and Cardoso were not legal spouses (or "spice", per Charlie Gordon's joke), but of course they were more than chess friends. She was a nice woman. Lombardy cried when she died, or so he said and why should he lie.
Mar-16-24  vonKrolock: quote <"When Ruth Cardoso died in February 2000, an enigmatic story about her childhood came to light. During the wake, a German, a close relative, revealed to the guests the obscure reasons why the chess player had difficulty breathing during games. Born in 1934, still in early childhood, Ruth accompanied her parents as they moved suitcases and bags to Germany, with the prospect of a more prosperous life. The miscalculation was disastrous."> end quote

And now follows the part translated in the previous post. The 'heavy breathing' would be a consequence of what was reported there... (* just recording this report here: there are still many details missing, chronology to understand (for instance, why the Volkl Cardoso were moving to what would be a dangerous place exactly at that moment ...)
