Johan Katzke: The Chessboard Biologist

Meet Johan Katzke, a rapid chess player whose rating trajectory resembles the ebb and flow of natural selection. From a modest 998 in 2022 to peaking at 1220 that same year, Johan's rapid rating has evolved with the unpredictability and resilience of the finest species in the chess ecosystem.

Known for a comeback rate of nearly 80% and a perfect 100% win rate after losing a piece, Johan’s games are a testament to survival of the fittest in the battlefield of 64 squares. His approach can be likened to a biological defense mechanism: sometimes retreating early (with an early resignation rate under 1%), but mostly adapting through a highly frequented endgame phase (76% of his games), where he thrives in the slow grind of metabolic chess energy.

Johan’s style is a curious blend of patience and persistence, with an average of 68 moves to victory, but interestingly, losses tend to drag on longer, averaging nearly 81 moves—proof that even when the genes don't align, he’s in it for the long haul.

A bit of a creature of habit, Johan prefers the early morning chess hours (7-8 AM) and late afternoon, boasting a peak win rate of 66.7% at 7 AM and another 60% around 8 AM—clearly grooming his tactical neurons when the brain is freshest and most ferocious. Saturdays show the highest success rate in his week, corresponding with a 53% win rate, perfect for those weekend chess hunts.

His most recent opponents include the likes of stenold, rezaslt, mig29zidan, tony_fred, and alonkadinov, where his record displays the classic evolutionary arms race: some prey escaped (0% wins), while others were caught with 100% efficiency. Johan’s repertoire remains top secret, with nearly 2,250 games giving him just under a 48% win rate — a true example of cryptic survival strategy.

Psychologically, Johan shows a modest tilt factor of 8, indicating he keeps his cool even when the pressure mounts—a vital trait for outwitting predators in the competitive jungle. With almost equal success playing with White (49%) or Black (46%), Johan Katzke is an adaptable organism, thriving in multiple chess niches.

So if you ever find yourself caught in Johan’s web, beware: this chess player is less bug, more strategic locust, able to swarm back from the brink and claim victory with evolutionary flair.
