Semen Grebeniuk - National Master
Semen Grebeniuk, known to many in the chess community as Grebeniuk-S, is a formidable National Master whose journey through the ranks is nothing short of inspiring—and occasionally amusing. With a career that shines brightest in blitz and bullet chess, Semen has dazzled opponents with a mix of sharp tactics, resilient comebacks, and an uncanny ability to make the average chess fan wonder, "How did that move even work?"
Rating & Performance Highlights
- Peak Ratings: Blitz - 2670, Bullet - 2772, Rapid - 2335, showing a clear preference for the fast-paced battles where quick thinking reigns supreme.
- Consistency: Maintaining a bullet average near 2666 with over 5,000 wins, Semen has proven once and again that lightning-fast reflexes and strategic foresight are not mutually exclusive.
- Impressive Comebacks: Sporting a 91.6% comeback rate and a nearly unbeatable 99.8% win rate after sacrificing a piece, Semen is the epitome of fighting spirit—never giving up, even when the chips are down.
Playing Style & Psychology
With a knack for lengthy endgames (averaging nearly 88 moves per win, because who wants quick draws anyway?), Semen enjoys turning what looks like a routine finish into a slow-burn thriller reminiscent of classic chess matches. A tilt factor of 16 suggests occasional frustration—but hey, even National Masters have bad days. Applying the motto, "If you’re going to fall, fall with style," Semen makes losses entertaining, and wins ruthless.
Favorite Openings
Semen's opening repertoire reveals a love for the Torre Attack Fianchetto Defense (boasting a win rate of 57% in blitz and 52% in bullet) and the ever-tricky Scandinavian Defense Mieses Kotrc Main Line, often catching his opponents off guard. Whether it's the subtle shifts in the Reti Opening Dutch Variation or the dynamic Dutch Defense Leningrad Variation, Semen’s openings promise both positional understanding and tactical fireworks.
Notable Streaks & Records
A longest winning streak of 24 games means that for a brief time, Semen was basically unstoppable—perhaps fueled by adrenaline or an unusually good cup of coffee. Their record against popular opponents like “ukigumo” and “nyx6” have been battles worthy of livestream commentary, with win rates hovering around the 50% mark—almost like a chess soap opera.
In Everyday Life
When not blitzing opponents online or analyzing complex endgames, Semen probably enjoys quirky puzzles and occasionally pondering life’s greatest mystery: why did the knight cross the board? Whatever the answer, Semen Grebeniuk is a chess player who combines talent, persistence, and just the right amount of humor to keep the game exciting for themselves and their fans alike.
Overall Performance
Semen, your recent bullet games demonstrate solid progress and consistent improvement. You have achieved a +63 rating change over the last month, with a positive upward trend, reflected by your strength adjusted win rate of about 50.3%. This steady ascent shows your increasing skill and effective adaptation to fast-paced games.
Strengths
- Opening Preparation: Your choice of openings such as the Scandinavian Defense, Dutch Defense, and Queens Pawn structures shows good variety and understanding. You maintain solid positions early in games, often achieving comfortable development.
- Endgame Technique: Several wins were achieved by converting small advantages and time pressure on your opponents, indicating confident endgame skills.
- Time Management: Most of your wins came from maintaining enough clock time under pressure, which is crucial in bullet chess.
Areas for Improvement

- Tactical Precision: Bullet games demand quick and accurate tactics. Some missed opportunities in critical positions suggest sharpening your pattern recognition and alertness.
