Sean Mullins

Sean Mullins (aka Hexaven) - The Relentless Wanderer of the Chessboard

Sean Mullins, known in the chess realm as Hexaven, is a player whose rating tells a tale of both daring boldness and delightful unpredictability. With a peak rapid rating of 1219 (achieved back in 2020) and a more recent bullet high of 397 in May 2025, Sean’s journey on the 64 squares is a rollercoaster that even seasoned commentators cheerfully admit is hard to predict.

Playing Style & Quirks

If we had to sum up Sean’s style in a single phrase, it would be: “Why stick to the beaten path when you can awkwardly dance your king all over the board?” Indeed, his favorite king (and favorite piece) is apparently the king itself, demonstrated by his infamous early king marches in bullet games — sometimes even moving it boldly to e2 and beyond. Don’t be fooled though; this isn’t just random wandering. Sean has a 68.7% comeback rate – a testament to his fighting spirit and ability to claw back from losing positions.

Early resignation is not Sean’s favorite option (just 7.75%), but watch out for his stamina – lose a piece, and he still manages to win around 32.5% of the time. On the downside, his longest losing streak hit a painful 11, proving even Hexaven has off days.

Openings: From Grob to Van 't Kruijs

Sean is the kind of player who keeps opponents on their toes by mixing unusual openings with curious variations. His Grob Opening in bullet games boasts a perfect 100% win rate over 3 games — maybe that’s his secret weapon or just pure chaos theory at work. The Van 't Kruijs Opening is another favorite, seeing success in both bullet and blitz formats, hitting a solid winning percentage close to 67%.

Favorite Time to Win

When it comes to timing, Sean's chess gods seem to shine brightest at 14:00 and 15:00 hours, where he enjoys a flawless 100% win rate. Weekday-wise, Wednesdays bring his best results, winning over half his battles on that day despite generally mixed fortunes otherwise.

Recent Memorable Battles

His most recent triumph was a fascinating encounter using the French Defense — except Sean played White and quickly took a king stroll on e2, e3, d4, and even e5, snagging a victory by his opponent’s resignation. You could say it was unconventional, or simply... Sean’s style. In contrast, his recent losses have often come fast and furious by checkmate, a reminder that sometimes his king’s adventures end abruptly.

Personality on the Board

Sean’s tilt factor is modest (11%), so if some gambit goes sideways, he’s more likely to shrug and jump back into the fray rather than throw his mouse across the room. After all, chess is as much about fun — and what fun is it if you don’t occasionally march your king into the unknown?

Whether you’re an opponent or a fan, Hexaven’s games are never dull, often unpredictable, but always entertaining — a true chess weekend warrior for the ages.
