Kévin Brégère (aka QuaivUn)

Meet Kévin Brégère, a rapid chess warrior whose rating rollercoaster would make even the boldest thrill-seeker dizzy. With a peak rapid rating of 626 achieved in March 2025 and a spotless daily rating maxing out at 800, QuaivUn doesn’t just play chess — he practically lives it.

Since stepping onto the virtual chessboard in early 2025, Kévin has played nearly 500 rapid games, boasting a respectable 236 wins to 210 losses and drawing 27 times. His style? Aggressive, tactical, and full of surprises. He enjoys the thrill of the comeback, with a comeback success rate of 69.2%, proving he’s never out till the last piece falls.

Kévin’s favorite weapons of choice belong to the shadowy 'Top Secret' opening — no details given — where he has a solid 51.5% win rate. When feeling a bit more conventional, he excels with the French Defense Knight Variation boasting an impressive 76.9% win rate. On the flip side, the Philidor Defense is his "not today" opening, with a sobering 28.6% success—sometimes you gotta yell “heck no” at the chess gods.

QuaivUn shines brightest around 8 PM, his personal prime time, where his win rate skyrockets to over 80%. Maybe it’s the evening coffee or the quiet of night, but opponents beware — that’s when Kévin is the sneakiest.

Fun fact: his longest winning streak is a jaw-dropping 10 games! (And yes, there was some serious bragging rights after that.)

Not one to shy away from sacrifices or resignations, Kévin has a pragmatic streak—he resigns early only 2.4% of the time, but when it’s time to call it quits, he does so on his own terms. Checkmate is his favorite way to celebrate a victory, clinching nearly 80% of his wins that way.

Lastly, Kévin’s endgame is pure artistry — with over half his games reaching the endgame phase, and an average of 60 moves before sealing a win, patience and precision are his middle names. Or at least they should be.

Whether he’s charming his foes with a Kings Pawn Opening Kings Knight Variation or leaving them scratching their heads with unconventional plays, Kévin "QuaivUn" Brégère is a player who brings both cunning and charisma to the digital chess arena.

Watch out chessboards, QuaivUn is plotting his next move!
