Jon Jacobs, aka FishThatRoared: FIDE Master Blitz Chess Biography
Jon Jacobs is an online chess player best known under the username FishThatRoared, with the extra bragging rights of a FIDE Master title. The account name sounds like a sea creature that learned to roar over a 5+0 board, and the career profile matches: thousands of fast games, stubborn endgames, and a habit of turning unusual openings into practical weapons.
His preferred arena is Blitz, where the clock is louder than the annotation. That speed has produced a massive body of work, including more than ten thousand blitz wins and a ten thousand win bullet record. The profile is not a quiet correspondence career; it is a high volume grind, with long streaks, hard resets, and enough material to fill a fishing boat.
Repertoire: Fishy, Sharp, and Hard to Predict
Opening choices are where FishThatRoared gets interesting. Instead of always walking the safe main line, the repertoire leans on oddities like the Barnes Defense and the Modern Defense. Those lines create messy positions where preparation can evaporate quickly and tactical instinct takes the wheel. He also plays with the white pieces in openings that force the opponent to work for a clear advantage early.
- Black weapons: Barnes Defense, Modern, Australian Defense, and Scandinavian Defense.
- White choices: Bird Opening Dutch Variation, Caro Kann Defense, French Defense, and Alekhine Defense.
- Style signal: frequent early checks, frequent captures, and a high endgame frequency.
Playing Personality: Roaring at the Clock
The numbers paint a competitive player with a low tolerance for passive chess. Early resignations are common enough to make a coach wince, but the comeback rate is high enough to keep opponents nervous. In short, FishThatRoared will abandon a dead fish quickly and then try to win a lost game with a sword.
- Longest winning streak: 22 games.
- Longest losing streak: 36 games, a reminder that even fish have dry spells.
- Most played opponent: geegeebye, with a record that proves online chess can be both funny and slightly tragic.
- Endgame frequency: about 72 percent, meaning the real fight often starts after the pieces have died.
As a FIDE Master, Jon Jacobs brings a title to the fast lane without losing the internet personality. FishThatRoared is the kind of player you want in a tournament pool: unpredictable, resilient, and always ready to make the next move feel like a surprise from the deep.
