Early Days and a Need for Speed
Beatriz Frattini, better known online as biaf13, carries the FIDE title of Woman Candidate Master and an unusual affection for the most chaotic format in chess: bullet. Her recorded online journey begins in 015 with a modest 645 blitz rating, but it did not take long for her to find where her heart truly belonged. Bullet chess rewards fast hands, bold instincts, and a willingness to flag your opponent without apology; biaf13 embraced all three.
Her bullet rating exploded from hundreds into the low 2000s over the next few years, a climb visible in her rating history.
A Repertoire of Chaos
Beatriz's opening choices read like a collection of internet chess folklore. The Blackburne Shilling Gambit appears in187 blitz games with a sparkling58.82 percent win rate, and she is equally at home in the Scandinavian Defense or the Sicilian Defense, often drifting into sharp lines where opening theory dissolves into pure survival. A typical trap from her favorite gambit looks a bit like this:
.Across all time controls, her results by opening show a player who is not afraid to dance with danger.
Rivalries, Streaks, and Comebacks
Every online chess saga needs a nemesis. For biaf13, that nemesis is Nery Junior José Antônio, who has defeated her28 times across35 meetings, making him a recurring boss battle. Fortunately, she also has a perfect antidote: copoamarelo, who has faced her13 times and never tasted victory.
Her longest winning streak reached13 games, while her longest losing streak stretched to14, a reminder of how cruel bullet chess can be. Yet she rarely resigns early, and her comeback rate sits ata remarkable82.45 percent. Losing a piece to Beatriz does not end the game; it just gives her an excuse to be more creative.
Legacy of the Clock
By2022, Beatriz touched a bullet peak of 2258 (2022-04-06)and a blitz peak of 2204 (2022-04-20), an improbable altitude for someone who started near the basement of the leaderboard. She wins over60 percent of her games against lower-rated opposition, though stronger players still give her trouble, and her endgame frequency of76 percent suggests she actually plays chess during the flagging chaos.
Her best time of day to play, according to the data, is6 AM, which fits a player who seems to operate on a different clock than everyone else. The title of Woman Candidate Master is her formal credential, but her real legacy is thousands upon thousands of bullet battles, each one fought at the speed of light, with a smile and a mouse click.
