Aaron Jacobson (WorriedEgg): International Master and Bullet Marathon Man
Who Is WorriedEgg?
Aaron Jacobson, known online as WorriedEgg, is a FIDE International Master with one of the most active accounts in the blitz and bullet pool. Despite the nervous-sounding username, his play is fearless, unconventional, and relentless.
His preferred time control is clearly Blitz, but his true superpower emerges in bullet, where he has played thousands of games and reached astonishing heights. He has peaked at 3435 (2026-08-03) in bullet and 3091 (2025-10-16) in blitz, and at one point he strung together a 76 game winning streak that left opponents little time to figure out what had hit them.
Opening Repertoire
Aaron does not play like a typical conservative title holder. With Black he happily enters the Scandinavian Defense and the sharp Elephant Gambit, while the Caro-Kann Defense is a regular companion with White. He also has a clear affection for the Amar Gambit, a cheeky opening that most International Masters would never dare to play in serious games.
His opening stats show serious volume in unusual lines. In bullet, his winning percentages with the Scandinavian Defense, Caro-Kann, French Defense, and Barnes Defense are very strong. As Black, his results with the Amar Gambit are particularly impressive, which suggests he enjoys making opponents solve strange problems while the clock ticks down.
Rivalries and Familiar Foes
Years of high-volume online play mean Aaron has built genuine rivalries. His most recurring opponent is Andy Woodward, who holds a narrow edge after a massive series of games. On the other side of the spectrum, yabbadabbadoooooooo has had a much rougher time against him. Other regulars such as tactic, ros1999, and joshuagarry have also logged hundreds of games against this tireless competitor.
Fighting Spirit and Key Numbers
Aaron is a comeback artist. His stats show an 80.58% comeback rate, and he still wins more than half of his games after losing a piece. That kind of resistance makes him miserable to face, especially in bullet where players often panic after a blunder. He also plays significantly better in rated games than casual ones.
- Longest winning streak: 76 games
- Bullet peak: 3435 (2026-08-03)
- Blitz peak: 3091 (2025-10-16)
- Rapid peak: 2417 (2025-06-01)
- Comeback rate: 80.58%
His bullet rating trajectory tells the story of a player who never stops grinding. Even a rare losing streak could not keep him down for long, and his best hour of the day is reportedly 1 a.m., when the rest of the chess world is sleepy and WorriedEgg is still calculating.
The Verdict
Aaron Jacobson is a true online chess gladiator. His enormous game volume, fearless opening choices, and willingness to grind through any time control make him a fixture in the blitz and bullet community. If you meet him at the board, do not let the username fool you. The egg is not worried. The egg is hunting.
