About Ummi Fisabilillah
Ummi Fisabilillah, known online as UF_10, is a FIDE-recognized Woman International Master whose true battleground is the one-minute clock. Since 2016, she has played thousands of rated online games, and the vast majority are bullet fights. She started near the bottom of the bullet ladder and climbed all the way to a bullet peak of 2739 (2026-07-15), which proves that raw volume, grit, and a fast mouse can turn a hobby into a serious title-level skillset.
A Bullet Career Forged in Volume
Her online journey began in September 2016 with a bullet rating near 1020. Within one month, she played 133 bullet games, won 95 of them, and blasted past 2000. That early explosion set the tone for a career built on relentless repetition. She grinds, adapts, and always comes back for more. Along the way she produced a 19-game winning streak, a longest losing streak of only 13 games, and a rating curve that just keeps rising through 2026.
Playing Style: Endgame Heart, Gambit Soul
Ummi loves unbalanced positions. As White, she frequently opens with the Nimzo-Larsen Attack or tests opponents with the Amar Gambit. As Black, she answers 1.e4 with the Scandinavian Defense and the French Defense, and she has especially strong bullet results in the Scandinavian. Her games are famously long: the average decisive contest runs past 80 moves, and endgames appear in more than 83% of her games. Even after losing a piece, she still wins about 47% of the time, which is a sign of serious defensive resilience.
The Rivalry That Built Her
No opponent defines her bullet career quite like Susanto Megaranto, who has faced her 301 times. Those marathon matches have been a hard school: she has taken 59 wins against 225 losses, with 17 draws. Another frequent rival, Gilbert Elroy Tarigan, has shared dozens more battles with her. These repeated matchups show a player who willingly steps back onto the board against stronger opposition, and her 82.48% comeback rate suggests she almost never fades quietly.
Timing, Tilt, and Tenacity
Like many online attackers, Ummi has her ups and downs. Her best hour of the day tends to be late evening, with a remarkable 60% win rate around 23:00. Against lower-rated players she wins about 64.5% of games, while against higher-rated opposition she still manages to grab nearly 29% of the points, which keeps her dangerous against anyone. Her early resignation rate is tiny at just 1.16%, so opponents know they have to prove the win until the very end.
Legacy of the Clock
Ummi Fisabilillah's path from a 1020 bullet beginner to a titled player is a reminder that online speed chess can be a genuine training ground. With thousands of games already logged and still climbing, she turns every spare minute into practical chess experience. She does not need a tournament hall to find beauty in the game: she finds it in the increment, in the scramble, and in the fight to the last second.
