Mona_Sax: A Career Built on Bullet Chess
Some names belong in a rainy noir alley at 2 AM, and Mona_Sax is one of them. Fittingly, her entire online chess identity runs on bullet chess, the fastest, most unforgiving format on the internet. Since arriving in May 2022 she has racked up more than 11,000 bullet games, a volume of clock-related violence that should probably require a permit. Her bullet rating eventually climbed to 2644 (2025-06-24) by June 2025, presumably achieved at an hour when most sensible people were asleep.
The Clock Is the Weapon
Here is the most telling stat in her whole file: Mona_Sax has won 2,725 games by timeout and only 1,928 by checkmate. She does not always beat you. She simply lets your flag fall and watches you realize it. With a tilt factor of just 10, she stays ice cold under time pressure, and her 86.5 percent comeback rate means opponents who think they have her dead to rights are usually mistaken. When a job does go badly, she does not linger: her early resignation rate sits at 21 percent, out the door before the sirens arrive.
Repertoire: Loyal, Obscure, Slightly Prehistoric
With White she leads with 1.e4 far more often than anything else, then gets creative. The Amar Gambit has been deployed hundreds of times, and her Barnes Opening: Walkerling wins at a stunning 92 percent in rapid, an opening so obscure that opponents lose precious seconds just being confused. As Black, she is essentially married to the Scandinavian Defense, with nearly a thousand bullet games answering 1.e4 with 1...d5. Her defensive lineup reads like a travel itinerary, featuring the Czech Defense, Australian Defense, French Defense, and Alekhine Defense. The Elephant Gambit remains undefeated in daily play at 6 for 6, and her fondness for the Colle: Rhamphorhynchus Variation suggests she may believe chess peaked in the Cretaceous period.
Enemies and Nemeses
Every assassin has a nemesis, and hers is Martim. They have met 166 times, and Mona_Sax is behind 63 wins to 86 losses. Has she considered simply playing someone else? Absolutely not. Meanwhile she holds a winning record over bessarabets across 107 meetings, lives on a knife edge of 46 to 47 against VictorDShade over 102 games, and uses timeless limitless for target practice with a dominant 63 to 29 score in 98 meetings.
The Dossier
- Her deadliest hour is 3 AM, where she wins over 60 percent of her games. Wednesdays are her best day of the week.
- Endgames appear in roughly 89 percent of her games, and her average win lasts 82 moves. She grinds in bullet the way others grind in classical.
- She has delivered 11,819 rook checks. Ladders are not a tactic for her, they are a lifestyle.
- Her longest winning streak is 14 games, comfortably outlasting her longest losing streak of 10.
- She wins about 18 percent better in casual games than rated ones, suggesting her true gift is violence without stakes.
Legacy
Is Mona_Sax the greatest bullet chess player of all time? No. Is she one of the most relentless, clock-hungry, 3 AM Scandinavian-playing figures in online chess? The 11,159 games and counting say yes. The flag is coming for you. It always was.
