L. C. Guimarães (aka Klaus-Guimalias)
Meet Klaus-Guimalias, a relentless tactician and a chess warrior who has been battling it out on the virtual battlefield since 2014. Starting modestly with a bullet rating shy of 900, Klaus catapulted his skills over the years, reaching an impressive peak of 1979 in bullet chess by April 2025. Not bad for someone who once lost all their first three bullet games!
With lightning-fast fingers and a brain wired for calculation, Klaus dominates in blitz (rapid-fire chess) with a peak rating soaring above 2150—a true speed demon on the board. Rapid chess? He’s no slouch there either, boasting a peak of over 2000 and an incredible win rate of over 76%.
Klaus is a brave soul who often boldly chooses the mysterious "Top Secret" opening (where even opponents are left scratching their heads). But when it comes to openings he can name, the Philidor Defense and English variations are his playgrounds—with win rates proudly flirting around the 50-77% range. English Opening King's English Variation? A whopping 77.27% success rate - talk about knowing your specialty!
His playing style combines strategic patience and daring all-in moves. He likes long fights—winning games after an average of nearly 67 moves and only giving up after more than 72 moves on losses (because who wants to quit early?). His endgame frequency is almost 80%, making him a gladiator who thrives in the late stages.
Klaus’s psychological constitution is enviable—a tilt factor of only 24 means he keeps his cool even under pressure. His best playing hour? 9 AM sharp, when the coffee kicks in and the brain cells fire up! His comeback rate is a staggering 86%, so if you catch him down a piece, beware: he might just turn the tables.
He has had some epic battles with frequent rivals such as deezan11 and pribot, testing his mettle in nail-biting contests. His latest documented win was a classy resignation victory employing Philidor Defense moves, showing his sharp eye for exploiting weaknesses.
Off the board, Klaus is probably a chess lover fueled by passion, caffeine, and a little bit of madness. With thousands of games logged, a balanced win/loss record, and a deep love for “Top Secret” strategies (though the secret might be that there is no secret), Klaus-Guimalias is a player to watch, laugh with, and maybe fear a little.
In summary: from humble beginnings to near-master flashes in bullet and blitz, with a penchant for long glorious endgames and a mind fearless enough to attack openings as if they were party invitations, L. C. Guimarães is the kind of player who turns the 64 squares into an epic saga where every pawn can become a hero, and every blunder... well, a funny story.
