Arthur Moura: The National Master with a Tactical Twist

Arthur Moura, widely known by their online alias arthuuur, is a chess player who proudly carries the prestigious title of National Master. Earning this title is no easy feat, but Arthur is no stranger to challenge, consistently pushing their limits across all time controls.

From Bullet to Marathon Matches

Arthur’s journey in chess began in the intense and chaotic world of bullet chess, where they quickly showed promise. Although early days saw a rocky start with a modest bullet rating around 1160, Arthur steadily climbed the ranks, peaking at a commendable 2048 in November 2019. But don’t mistake this bullet maestro for a one-trick pony; Arthur also shines in blitz with a peak rating soaring to 2244, and even conquers the long-form daily games with a phenomenal peak of 2351 in 2024.

Playing Style: Endgames and Comebacks

Known for a remarkable 68.67% comeback rate, Arthur is the player who never truly throws in the towel. Their endgame frequency is an imposing 69.13%, which means they’re comfortable grinding down opponents in the late stages, like a grandmaster with a dessert craving. Their preferred weapon? Maneuvering into endgames with patience and precision, often squeezing wins in games lasting around 60 moves. Also, wielding a white advantage with roughly a 53.4% win rate, Arthur knows how to make the first move count.

Psychological Profile: Tilt? What Tilt?

Arthur’s psychological resilience can be summed up with a tilt factor of just 15, which in chess terms means they might lose their cool only once in a blue moon. Plus, their best hour to play is around 4 PM — so if you want to catch Arthur at peak form, set your alarm just right.

Opening Choices: The Mysterious and the Classic

Arthur’s opening repertoire is intriguingly eclectic: while "Top Secret" openings dominate their games (because even masters like a little mystery), they show boldness with sharp yet balanced choices such as the Reti Opening and the Queen’s Gambit Declined Marshall Defense, boasting win rates as high as 77.78% and near 70%, respectively.

Recent Battles

Arthur's latest triumph was a swift and satisfying checkmate against Blacksray in June 2025, showcasing their tactical finesse with a flourish of Qxb7#. Despite occasional setbacks like a loss by time against OmerFarSol2250, Arthur's determination is undeniable, making every game an exciting spectacle.

In Summary

Arthur Moura is not just any chess player. They are a National Master who embodies grit, strategic depth, and a pinch of mystery. Whether out there blitzing at lightning speed, bulleting their way to victory, or plotting long-term dominance in daily games, Arthur keeps the chessboard heated and the pawns trembling. Opponents beware: this is a player who might resign gracefully, but only to come back swinging stronger.
