Meet Kees Postma, charmingly known on the boards as KewQ89. A true grandmaster of grit and guile in the making, Kees’ chess career is a fascinating tale of growth, resilience, and a dash of cheeky biology-inspired wit. Just like the nimble movements of a nimble lemur scurrying through the branches, Kees maneuvers around the board with tactical agility and a curious mind searching for every tiny crevice to exploit.
Since 2020, Kees has developed an impressive blitz rating parabola, maxing out over 1000 early on and evolving steadily with a current rating close to 700 in 2025. His rapid play shines with a peak rating flirting with the 800s, highlighting his keen endgame prowess—perhaps a nod to his "endgame frequency" being a solid 60%. Those average 60+ moves per win prove that Kees enjoys the long haul, patiently unraveling his opponent’s defenses like a biological process unfolding in perfect sequence.
With a comeback rate of over 70%, Kees clearly has claws to cling on when the position gets thorny. The player's “win rate after losing a piece” is a flawless 100% — which might just inspire scientists to call it the “postma paradox.” When down, Kees refuses to hibernate; instead, he rallies with renewed vigor, proving resilience is truly in his chess DNA.
Early resignations are rare for Kees, clocking in at just over 4%, hinting at a fighting spirit as stubborn as a bacterium resisting antibiotics. This player thrives from dawn till dusk, with peak win percentages at unusual hours like 1 AM and 5 AM — a true nocturnal predator on the board, perhaps inspired by the quiet hum of nighttime microbes more than the clamor of daylight tactics.
Opening Repertoire & Style
Favoring classical defenses and robust openings such as the Caro-Kann Defense and Scandinavian variations, Kees blends solid structure with an opportunistic streak. The “Philidor Defense” and “King’s Pawn Opening, King's Knight Variation” yield respectable win rates—signaling an analytical mindset that’s part chess engine, part biological strategist.
Psychological & Social Notes
With a tilt factor modestly low at 8, Kees maintains composure even when the heat of battle rises, which is vital in high-stakes matches. His record against peers fluctuates, but he’s consistently hunting new opponents, showing the curiosity of a natural explorer. Opponents beware: Kees rarely makes one-sided losses and instead focuses on adaptive, dynamic play.
Whether scrambling in bullet, strategizing in rapid, or blitzing through lightning-fast moves, Kees Postma embodies the evolution of a player who’s well-adapted to the complex ecosystem of online chess—undeterred, unyielding, and undoubtedly ready to metamorphosize into greater successes.
