Filiz Osmanodja (Jabberwockiez): Chess Biography of a Woman Grandmaster
Meet the Jabberwock
Filiz Osmanodja is a German chess player and FIDE Woman Grandmaster who competes online as Jabberwockiez, a handle borrowed from Lewis Carroll's most famous monster. The branding fits. Her all-time leading checking piece is the queen, with 4,559 career checks delivered, and opponents who wander into her lair tend to exit quickly. By preference she is a blitz chess player. By recent practice, she has become something considerably scarier.
From Blitz Rocket to Bullet Machine
Her online arrival in February 2019 was not subtle: nearly 900 rating points gained in a single 65-game month. The climb continued until she touched 2340 (2020-01-15) in January 2020, at which point the blitz graph apparently decided it had done enough and went on sabbatical. Then came the 2025 bullet renaissance: more than 2,700 bullet games between March and August alone, a peak of 2470 (2025-04-05) in early April, and a modern mystery in which her bullet and blitz ratings now live on different continents and are reportedly not on speaking terms.
Opening Repertoire: Sicilian Today, Sicilian Tomorrow
More than 500 games of Sicilian Defense across blitz and bullet make her loyalties clear. Her most productive branch is the Sicilian Defense: Closed, a 54% scorer in blitz and a flawless 4-0 in rapid. With the white pieces she reaches for the French Defense: Exchange Variation (close to 59% in blitz) and a menacing 69.6% scoreline with the Alekhine Defense. Every monster has a nemesis, and hers is the Amazon Attack: 40 blitz encounters, a 27.5% win rate, and presumably many sighs.
In bullet she goes full paleontology, leaning on the Modern Defense: Pterodactyl Variation, a Rhamphorhynchus line whose full name appears partially classified in the archives, and the trusty Amar Gambit at a coin-flip 50%. A taste of the bread and butter:
Playing Style: Resign Politely, Strike Repeatedly
The numbers sketch a very specific creature. Her early resignation rate is 88%, meaning lost positions are treated like expired milk: no lingering, no bargaining, straight to the bin. Yet her comeback rate runs 85.6% and only 1.4% of her losses are one-sided, so when actual hope exists, she revives like a horror movie villain. Wins average 74 moves and 81% of her games reach the endgame, so opponents should cancel their evening plans.
- First move: 1.e4, played 1,755 times in 2025. She has played 1.d4 exactly once. Somewhere out there is one very confused opponent.
- Best hour: 6:00 AM, with a 55.6% win rate. By 7:00 AM it collapses to 38.6%. The coffee window is real and it is narrow.
- Tilt factor: 9 out of 100, calmer than most libraries.
- Longest winning streak: 12 games. Longest losing streak: a mere 9, swiftly avenged.
- First capture: around move 6, because pleasantries are for after the game.
Rivalries and Reliable Victims
Her most frequent sparring partner is Goran Galiot, 11 games with a narrow 6-5 edge, the sort of rivalry that deserves its own group chat. Jayaraman B has learned respect the hard way, trailing 2-7, while fualls2 remains the official problem child, leading 7-2. Micro-feuds like these are the spice of the online chess food chain.

Callooh! Callay!
The original poem ends with a warning: beware the Jabberwock, my son, the jaws that bite, the claws that catch. The chess version reads: beware the queen that checks, the Sicilian that snaps, and the alarm clock set for six. With chortles in her wake, she goes galumphing on, one bullet game at a time.
