Henrique Oliveira — aka rei-calvo

Henrique Oliveira, fondly known in the chess biosphere as rei-calvo, is a Rapid player with a rating oscillating like a lively heartbeat — from a lofty 645 all the way down to a modest 110 in 2025, settling in with a current rating of 191. His games reflect a fascinating lifecycle of wins, losses, and draws, with a curious survival rate of 31 wins to 40 losses and the occasional 4 stalemates.

A tactical chameleon, Henrique has dived into a variety of chess openings with a mixed bag of success, sometimes sprouting wins from unlikely soil. His strongest root systems seem to be in the Undefined opening (a 75% win rate!) and the Nimzowitsch Defense where he has triumphed two-thirds of the time. Yet, like any evolving organism, he struggles against the King’s Pawn Opening Kings Knight Variation and Alekhine’s Defense, both resulting in zero wins so far.

Oliveira’s playing style appears methodical and patient, with an endgame frequency of just over 50%, signaling a penchant for prolonged battles — some games reaching nearly 39 moves on average before a win, showing endurance comparable to a chessboard marathon runner.

Known for his comeback prowess (a 45% comeback rate!), Henrique exhibits remarkable resilience — much like a tenacious bacterium thriving even after the loss of a vital piece, boasting a perfect 100% win rate after losing material. However, he occasionally suffers from tilt, with a tilt factor of 7%, indicating that even the toughest critters can get a little rattled.

Time-wise, Henrique is an early bird and a night owl — achieving striking win rates at odd hours such as 1 AM, 22 PM (10 PM), and 17 PM (5 PM) with wins at these hours hitting 100%. Weekend Saturdays are particularly fruitful, with a near 60% success rate.

Facing opponents like claytonastrid and akash_chourasiya, Henrique has scored perfect wins, while others like ivanarlynx and theblackcreature leave him still hunting for his first victory — proving the ecosystem of Chess Masters is dynamic and ever-evolving.

Henrique Oliveira’s journey through the complex biosphere of chess is a testament to adaptation, strategy, and the occasional gambit gone wild. One can say he’s not just playing chess — he’s partaking in a captivating biological experiment, where every move carries the DNA of genius, luck, and a touch of bald-headed charm.
