Bullet’s Friendly Neighborhood FM
Koosha Jaferian, known across the chess world as MrKooshaChess_Twitch, is a FIDE Master with a serious addiction to bullet chess. Since 2017 he has burned through tens of thousands of online games, building a reputation as a fearless clock‑puncher who treats every second like a weapon. His Caro-Kann Defense and Nimzo-Larsen Attack form the core of a repertoire that never seems to run out of venom.
The chart tells the story: Koosha’s bullet rating climbed from the 1900s into the stratosphere, peaking at 2958 (2026-08-03). His blitz game has also soared past 2800, reaching 2804 (2026-02-27). He may hold the title FM, but his online rating army makes him look like a GM in training.
Repertoire of a Speed Demon
As White, Koosha loves the quiet look of the Nimzo-Larsen Attack, often opening with b3 and daring opponents to figure out his plans. In bullet alone he has played the Nimzo‑Larsen more than 2,600 times, scoring well above 60 percent. As Black, he answers almost everything with the Caro-Kann Defense, the ultimate solid shield for chaotic time scrambles. In rapid games his Caro‑Kann is even more dangerous, with a win rate close to 80 percent.
Rivalries That Never End
Every bullet warrior needs a worthy dance partner. Nobody has faced Koosha more than nissou-ach, who has met him 263 times. Koosha leads that series with 175 wins. Hoang Minh Tho Do is another familiar face, having battled him 227 times, and Koosha again holds a comfortable edge. These long‑running rivalries are the heartbeat of his online chess life.
