Luís Costa: The Tenacious Chess Adventurer

Meet Luís Costa, also known in the chess wilderness as siulcosta, a player whose journey through the 64 squares resembles a rollercoaster operated by a caffeine-fueled mastermind. Luís thrives most in rapid chess, where he’s battled over a thousand games with a win rate just shy of 49%. His rapid rating skyrocketed impressively from a humble 589 in 2021 to nearly hitting the thousand mark at 954 in 2025 — talk about leveling up!

When the clock speeds up in blitz, Luís can be a bit inconsistent, oscillating between a sneaky 675 and a flashier 1044 peak, teaching everyone that sometimes, slow and steady isn’t the only way to checkmate. In daily matches, Luís is practically undefeated, boasting a flawless 100% win rate across his limited encounters — patience definitely pays off! Bullet games tell another story, where rapid-fire decisions resulted in some tough losses, but never without a fight.

Luís is no stranger to dramatic comebacks, with an impressive 63.5% comeback rate that would make even the most stoic chess engines blink twice. Losing a piece? Not a problem. Luís bounces back with a perfect record whenever down material — the ultimate resilience guru of the chessboard. However, early resignation isn't his favorite tune, as he only taps out about 8% of the time, preferring to battle on with relentless endgame prowess nearly half the time.

Psychological trends say he sometimes feels the heat—tilting moderately so—but his ability to outperform in rated games compared to casual ones by more than 24% shows he brings his A-game when the stakes are real. With a longest winning streak of 9 and a current streak going strong, Luís might just be the underdog story everyone is waiting to root for.

Off the board, Luís’s opponents are a colorful cast—some he conquers every time, others less so. But no matter the adversary, the chess warlord known as Luís Costa keeps charging forward, armed with clever tactics, undying perseverance, and a dash of chessboard charm.

Checkmate or not, the game’s never dull when Luís is in play!
