What is the name of the countess in Pushkin's 'The Queen of Spades'?

The countess in Alexander Pushkin's The Queen of Spades is Anna Fedotovna. She is the elderly grandmother of the narrator Tomsky and the mysterious source of the three-card gambling secret at the center of the story.

According to Tomsky, the countess once lost a fortune playing faro in Paris. She then learned a winning sequence—traditionally identified as the three, the seven, and the ace—from the enigmatic Count of Saint Germain. Years later, the German army officer Hermann becomes obsessed with discovering the secret. He gains access to the countess through her young ward, Lizaveta Ivanovna, but his threatening confrontation ends in the countess's death.

Lizaveta is the most likely distractor because she is closely tied to the countess and is important to Hermann's plan, but she is not the countess. Pushkin wrote the supernatural novella in autumn 1833 at Boldino, and it was first published in March 1834. Its blend of gambling, psychological obsession, and the uncanny later inspired operas by Tchaikovsky and other composers.
