Leo Dux - The Bullet Blitzer Extraordinaire

Meet Leo Dux, known in the online chess realms as kembahaca, a formidable force in the fast-paced worlds of Bullet and Blitz chess. Since diving into the chaotic ocean of online chess around 2015, Leo has been gradually building an impressive career with a career peak Bullet rating of 2088 (September 2021) and a Blitz peak of 1896 (July 2021). His Rapid rating recently touched 1517, proving that even outside of the lightning-fast games, he holds his own.

Chess Playing Style

Leo is no stranger to early resignations, occasionally waving the white flag with an impatient 0.51 resignation rate. But don’t let that fool you! This guy loves the endgame chaos, with a whopping 89.24% of his games extending into the final stages. On average, his wins and losses hover around 77-78 moves, which tells us one thing: Leo plays the long game, grinding opponents into submission or gracefully bowing out when necessary.

A tactical maestro, Leo boasts an astonishing 83.29% comeback rate and is quite adept at bouncing back even after losing precious material. However, his one-sided loss rate is a humble 0.84%, so even when the going gets tough, he rarely crumbles spectacularly.

Opening Repertoire & Success

Leo’s chess opening choices are as eclectic as his game count: the Nimzowitsch Larsen Attack Classical Variation is a fan favorite, with over 9,600 games and a solid 51.87% win rate in Bullet alone. The Owens Defense and Reti Opening Queenside Fianchetto Variation also feature prominently, showing a preference for hypermodern beginnings that keep opponents on their toes.

Performance Trends & Psychological Insights

Leo prefers to strike in the wee hours, with his best time to play being around 2 a.m. (UTC), when the world is quiet and the chessboard lights up his competitive spirit. His tilt factor is relatively low at 15, meaning he keeps his cool better than most — except maybe after a long series of losses, which nobody enjoys.

Interestingly, his win rate is slightly better with White (50.59%) compared to Black (48.7%), but he’s no slouch regardless of color. Leo is also a bit of a punctual chap: 51.65% win rate during the 0th hour and a notable 54.28% around 2 a.m. show his peak alertness times.

Career Highlights & Notable Games

Over the years, Leo has amassed an impressive record of nearly 30,000 Bullet wins with tens of thousands of games under his belt across all formats. His longest winning streak is an eye-watering 21 games, and his current streak (at last update) remains positive with one win on the board.

One of his recent wins was an elegant demonstration of skill using the Nimzowitsch Larsen Attack Symmetrical Variation, ending with a classic checkmate in under 35 moves, proving that this seemingly quiet and esoteric opening packs a punch in Leo’s hands.

The Man Behind the Username

Behind the username kembahaca lies a player who takes the lightning-fast and adrenaline-pumping Bullet format seriously, yet never loses the fun. Whether throwing down the gauntlet in Owen’s Defense or pioneering with Nimzowitsch Larsen, Leo navigates the 60-second duels with a blend of grit, cunning, and a dash of humor.

When not blitzing pawns and queens off the board, Leo probably enjoys analyzing games with the passion of a detective on a thrilling case or happily shaking his head at some of his own blunders (because who hasn’t!). His chess journey is as much about growth as it is entertainment, making him a respected and entertaining member of the online chess community.
