Olivier Bourseau (Obmu) - The Resolute Rapid Warden

Olivier Bourseau, who often goes by the enigmatic username Obmu, is a persistent and passionate chess enthusiast navigating the thrilling battlefields of rapid and daily games. His journey in the world of chess shows the true spirit of a player who neither surrenders easily nor allows setbacks to hold him down.

Rating and Progress

Starting out with a peak rapid rating of around 1180 in early 2021, Olivier has experienced the ups and downs that every determined player faces. His current rapid rating hovers around the 770-800 mark, showing that he consistently stays in the grind against worthy opponents. He's also dipped a toe into blitz and daily formats, showcasing a well-rounded love for the game.

Playing Style and Stats

Olivier’s style is one of endurance, patience, and resilience, with an impressive 66% frequency of endgames and an average game length of about 63 moves to win. He stays cool even after losing material — his comeback rate stands at a solid 75.7%, proving he’s not about to throw in the towel when things get tough. However, a tilt factor of 15% means he’s only human and can show some frustration — but who wouldn’t after battling through hundreds of rapid games?

A curious fact: Olivier tends to play his best during the evening hours, with the 20:00 slot being his prime time when win rates peak. The number 20 might just be his lucky hour!

Openings and Tactical Arsenal

Olivier keeps his strategic cards close to his chest with his favorite "Top Secret" opening — a mysterious cloak that covers over 5000 games with a win rate just shy of 46%. When we do get a glimpse of his repertoire, it includes gems like the Reti Opening and Bishop’s Opening, both boasting a perfect 100% win rate (albeit from a couple of games, but hey, who's counting small samples?). He's not afraid to experiment with the Nimzowitsch Defense either.

Notable Games & Recent Battles

In his latest noteworthy encounter, Olivier triumphed by resignation using a defense rooted in the Nimzowitsch Defense — demonstrating a solid grasp of counterplay. His games often reflect a tactical awareness that demands his opponents to remain vigilant or face creative flurries.

Personality on the Board

With over 2,300 wins and nearly as many losses in rapid chess, Olivier embodies the quintessential club player’s spirit — battling endlessly, learning from each game, and keeping the chessboard as his second home. Though his win rate is modest at about 46%, his dedication is anything but.

Opponents beware: whether it’s a rapid slugfest or a leisurely daily duel, Obmu never ceases to press on, sometimes ending games by checkmate, other times softly coaxing a resignation. Classic sportsmanship and fighting spirit go hand in hand in his playing style.
